Error cb never called - Исправление ошибок и поиск оптимальных решений проблем

When running the npm install command, sometimes you will have an npm error that causes the install to fail.

The error says the cb() function is never called as follows:

npm ERR! cb() never called!

npm ERR! This is an error with npm itself. Please report this error at:
npm ERR!     <https://github.com/npm/npm/issues>

npm ERR!   A complete log of this run can be found in:
npm ERR!   /Users/nsebhastian/.npm/_logs/2022-06-13T07_08_32_041Z-debug-0.log

The cb() function mentioned above is a vanilla callback function. The function was used by the npm install command to mark when an install is completed.

The error means that the installation process was interrupted and left unfinished.

The cause of this error varies from outdated npm package and cache, a limited memory space, and an incompatible node version.

Here are some things you can try to fix the cb() never called error:

Check the npm version and cache
Delete the package-lock.json file
Check the strict-ssl config
Check if you have enough memory for the packages
Define the node version in package.json file (for Heroku)

Let’s see how you can fix the error with the steps above.

Check your npm version and cache

An outdated npm cache may trigger the error, so you can try to fix the error by clearing the cache.

Run the following command from your terminal:

Once the cache is cleared, run the npm install command again.

If that doesn’t work, then make sure you are using the latest npm version. At the time of this writing, the latest npm version is 8.12.1.

Use the following commands to check and install the latest stable npm version:

# 👇 check npm version
npm -v

# 👇 install the latest npm version
npm install -g npm@latest

# 👇 if blocked, add sudo command
sudo npm install -g npm@latest

Sometimes, a global installation with the -g flag may get blocked because of a permission issue.

Add sudo to perform the installation with admin privileges.

After the npm is updated, run the npm install command again.

Delete your package-lock.json file

If you still see the error, then you may need to delete the package-lock.json file generated in your project directory.

The reason is that npm generates two different lockfile versions depending on its version.

npm v5 and v6 generated lockfile version 1, and v7 onward generated lockfile version 2.

You can open the package-lock.json file and see the lockfileVersion property:

{
  "name": "r-app",
  "version": "0.1.0",
  "lockfileVersion": 2,
  // ...
}

Delete the package-lock.json file and try running the npm install command again. Some people say it fixed the issue.

Check the strict-ssl configuration

If you have firewall protection on your computer, then the error may appear when npm do SSL key validation for the install process.

To resolve this error, set the strict-ssl to false:

npm config set strict-ssl=false

And npm won’t do SSL certificate validation when running installation via https.

Check for your memory space

The npm install command can generate a node_modules/ folder that is more than 1GB in size.

A React application generated using create-react-app has a node_modules/ folder that’s around 200MB.

Your local or production environment may not have enough space, so the installation process was interrupted.

It’s not possible to determine the space needed for your node_modules/ folder, so you can only get an estimation.

Try to get at least a few gigabytes of empty space in your computer before running the installation again.

Define the node engines config in package.json

When you see the error on cloud platforms like Heroku and AWS, then it’s possible that the Node.js version used to run the installation is incompatible with your dependencies.

You can specify the node version required by your application in the package.json file.

Consider the example below:

{
  "name": "example-app",
  "description": "My application",
  "version": "1.0.0",
  "engines": {
    "node": "16.x"
  }
}

Without specifying the version, cloud platforms will use their own default version. As of this writing, Heroku uses Node v16. Not sure about AWS.

Run the node -v command to find the node version installed on your computer, then specify the same version in the package.json file as shown above.

Finally, commit and push the update. See if the issue is resolved.

Conclusion

The above methods are the most relevant fixes for cb() never called issue.

Sometimes, the error also happens because of a connection timeout, so you can check if you have internet connectivity issues before running the install command again.

Make sure that you can access https://registry.npmjs.org/ from your browser.

If you need more help, you can open a new question on Stack Overflow. Add the detail of your error and mention that you have tried the fixes in this article.

Thanks for reading! 🙏

If you have npm version 5 or above, try this first:

$ sudo npm cache verify

Otherwise:

$ sudo npm cache clean

My node and npm versions are:

$ node -v
v0.10.0

$ npm -v
1.2.14

If you have updated angular cli, npm, node, you don’t need to do anything more. Just run the command below to resolve the issue. This command also resolves the issue of «unexpected end of line».

npm install --no-package-lock

IMPORTANT! The solution below is now regarded as unstable, and you should use Node Version Management instead: Node Version Manager on Github. David Walsh also has a good introduction to NVM. NVM works beautifully and I’ve been using it to manage legacy WordPress projects for a few years.

Please don’t use this — use NVM

I just had this exactly issue when trying to install the Sage theme for WordPress. When I ran npm install on the theme directory, it failed.

Looking in the dependencies in package.json, I could see that the engine I was running for Node was out of date. Running node -v on the command line showed that I was on v0.10.9, and the latest version of Sage requires >= 0.12.0

So here’s the fix for that. These steps are from David Walsh’s blog

Clear your npm cache: sudo npm cache clean -f
Install the latest version of the Node helper: sudo npm install -g n
Tell the helper (n) to install the latest stable version of Node: sudo n stable

You should then get a progress display, after which you will be up to date.

When I ran npm install after doing this, everything worked fine, and I was able to run gulp to build the initial dist directory.

Do you have a specific version of "npm" specified under "engines" in your package.json? Sounds like NPM v1.2.15 resolved the issue (and Heroku has available). I was getting the same problem with "1.1.x".

Since NPM 6 you can do a clean install.
That was the only solution which worked for me.

Just run the following:

npm clean-install

Notes:

You might also manually remove the node_modules folder and try again in case the command above failed.
If still doesn’t work, the global cache might be broken, try running npm cache clean --force and then do a clean install.
The clean-install command works on npm 6 and above. For older versions consider checking the other answers below.

I had the same problem with NPM version 1.3.11, and solved it simply by re-running the exact same command multiple times («npm update -g» in my case). The error popped up for a different package on each subsequent run and eventually everything updated successfully.

For me at least, it seems like it was being caused by a network issue (corrupted downloads). I was also getting an error about an invalid package, which I was able to resolve by deleting all instances of «tmp.tgz».

Edit: (Probably unrelated, but in case this helps anyone: I was using Windows, and started a command prompt as an Administrator after receiving the initial error).

I had the cb() never called! error, and none of the answers here directly worked for me. I was running Node v8.11.2, and I had to manually delete the package-lock.json file to get anywhere. After doing this, I ran npm cache verify per what some of the answers recommended. Then, running npm i yielded the following result:

npm notice created a lockfile as package-lock.json. You should commit this file.

Knowing that this is an old question and many of you had provided your answers. Just to share my experience with this error and how I fixed.

This all started after I upgrade my Node version to > 12, I did go through all the answers and try to follow steps clearing npm Cache, deleting the node_modules folder. No one of them resolve my problem.

The root cause in my case was proxy restricting installation. I deleted the proxy settings to fix the problem.

Check if you have any proxy config
```
npm config list
```

Delete them by

npm config delete proxy
npm config delete http-proxy
npm config delete https-proxy

Now try
```
npm install
```

I suggest: Switch to Yarn! — Yarn is a package manager which uses the same package.json file and node_modules folder as npm.

With npm I had the same problem: On a CentOS 6 install I got the ERR cb() never called error repeatedly and could not find a way to make npm reliably complete installation of some packages (like webpack for example). — Yarn works flawlessly, even on flaky network connections.

Migration to Yarn is easy. Most subcommands are the same. They have a good Migration guide. Read on to the handy CLI commands comparison at the end.

Try switching your network,
somehow switching network worked for me.

I have tried many things mentioned in other answers, like:

npm cache clean —force
Delete existing node_modules, delete package-lock.json, and reinstall using — npm i
npm cache verify
npm clean-install

None of the above worked for me, might work for you.
Try your luck.

It appears that particular dependency versions can cause this issue. For example, gulp-uglifycss 1.0.7 has this problem (see https://github.com/rezzza/gulp-uglifycss/issues/15).

If you are allowing major or minor version updates in your packages.json via ^ or ~, remove those characters thoughout the file and try another npm install. If it works that time then you’ll be alright after you have the fun of narrowing down which package is causing the problem.

I too faced the same problem today as I force stopped the npm package download in between due to internet issues.

I tried various things like,

Running sudo npm cache clean -f — which did not work as expected
Clean uninstalling node and reinstalling it — which as well didn’t work

I finally tried to delete the folder containing the npm cache that was creating the problem. I ran the following command,

sudo rm -rf /Users/{user_system_user}/.npm/

Then I tried installing the package that was stuck and everything worked like a charm.

P.S: replace {user_sytem_user} according to the current user of your system.

I’ve started using GitHub Actions to test projects as well as running builds. Heroku is part of this playground. While working, I stumbled across an issue that took some time to fix. Sharing here my notes for others to benefit. When you come across npm ERR cb() never called, you might want to try these steps to fix the issue:

npm ERR! cb() never called!npm ERR! This is an error with npm itself. Please report this error at:
npm ERR!     <https://github.com/npm/npm/issues>

As mentioned, in my case it was on GitHub:

From researching the issue, I’ve learned this also appears to happen a lot on other npm packages like React Native and Meteor but also on services such as Heroku. I’ve discovered various solutions to fix the issue I’d like to share:

Clearing the NPM Cache & Upgrading NPM #

If this issue comes up on your local development machine, it might pay to clear the cache:
```
npm cache clean -force
```
Secondly, ensure you are running the latest version of npm:
```
npm install npm@latest -g
```
Delete your node_modules before running an install too.

Fixing your NPM version #

It’s been noted, that hard defining the required node version helped. For this, you will need to append this to your package.json:

"engines": {
  "node": "0.8.x"
}

Doesn’t fix it? #

If this doesn’t fix it you could raise the question with details on Stackoverflow. Feel free to mention this site with the things you have already tried.

🙏🙏🙏

Since you’ve made it this far, sharing this article on your favorite social media network would be highly appreciated 💖! For feedback, please ping me on Twitter.

How to fix npm err! cb() never called! issue

Posted on Jun 13, 2022

Learn how to fix the npm error cb() never called issue

When running the npm install command, sometimes you will have an npm error that causes the install to fail.

The error says the cb() function is never called as follows:

The cb() function mentioned above is a vanilla callback function. The function was used by the npm install command to mark when an install is completed.

The error means that the installation process was interrupted and left unfinished.

The cause of this error varies from outdated npm package and cache, a limited memory space, and an incompatible node version.

Here are some things you can try to fix the cb() never called error:

Check the npm version and cache
Delete the package-lock.json file
Check the strict-ssl config
Check if you have enough memory for the packages
Define the node version in package.json file (for Heroku)

Let’s see how you can fix the error with the steps above.

Check your npm version and cache

An outdated npm cache may trigger the error, so you can try to fix the error by clearing the cache.

Run the following command from your terminal:

Once the cache is cleared, run the npm install command again.

If that doesn’t work, then make sure you are using the latest npm version. At the time of this writing, the latest npm version is 8.12.1.

Use the following commands to check and install the latest stable npm version:

Sometimes, a global installation with the -g flag may get blocked because of a permission issue.

Add sudo to perform the installation with admin privileges.

After the npm is updated, run the npm install command again.

Delete your package-lock.json file

If you still see the error, then you may need to delete the package-lock.json file generated in your project directory.

The reason is that npm generates two different lockfile versions depending on its version.

npm v5 and v6 generated lockfile version 1, and v7 onward generated lockfile version 2.

You can open the package-lock.json file and see the lockfileVersion property:

Delete the package-lock.json file and try running the npm install command again. Some people say it fixed the issue.

Check the strict-ssl configuration

If you have firewall protection on your computer, then the error may appear when npm do SSL key validation for the install process.

To resolve this error, set the strict-ssl to false:

And npm won’t do SSL certificate validation when running installation via https.

Check for your memory space

The npm install command can generate a node_modules/ folder that is more than 1GB in size.

A React application generated using create-react-app has a node_modules/ folder that’s around 200MB.

Your local or production environment may not have enough space, so the installation process was interrupted.

It’s not possible to determine the space needed for your node_modules/ folder, so you can only get an estimation.

Try to get at least a few gigabytes of empty space in your computer before running the installation again.

Define the node engines config in package.json

When you see the error on cloud platforms like Heroku and AWS, then it’s possible that the Node.js version used to run the installation is incompatible with your dependencies.

You can specify the node version required by your application in the package.json file.

Consider the example below:

Without specifying the version, cloud platforms will use their own default version. As of this writing, Heroku uses Node v16. Not sure about AWS.

Run the node -v command to find the node version installed on your computer, then specify the same version in the package.json file as shown above.

Finally, commit and push the update. See if the issue is resolved.

Conclusion

The above methods are the most relevant fixes for cb() never called issue.

Sometimes, the error also happens because of a connection timeout, so you can check if you have internet connectivity issues before running the install command again.

Make sure that you can access https://registry.npmjs.org/ from your browser.

If you need more help, you can open a new question on Stack Overflow. Add the detail of your error and mention that you have tried the fixes in this article.

npm ERR! cb() never called! #1916

I want to install create-react-app but bump along with this bug, i have tried many solutions/articles and in stack overflow like, cache verify, cache cleaning, and many stuffs but still making this error, any help for this problem ?

The text was updated successfully, but these errors were encountered:

I also encountered the same error on:
Node v14 and v12 alpine on docker
NPM v6.14.8

I have similar issue while trying to use create-react-app.
node v14.13.1
npm v6.14.8

is there a possible fix for this error.

Can confirm that this worked for following environment.

man i just wanted to code and have a job. now my computer is broken because of this problem ,probably because of all the things ive done/downloaded etc. lol

@lewsea try removing node & npm completely and re-install. see if that fixes the issue.

@detj already did that 😑 but still get the same error

@lewsea can you try npm install -g npm@next-7 and see if that works?

Same here. Trying to run this command:
c: npm adduser —registry https://pkg.domain.io

npm -v : 6.14.8
node -v: v14.5.0

Sometimes I see the same error on Win10 / Node14.13.1 / Npm7. I was deleting all cache, reinstalling nodejs and npm, but error is still there. It may be related to an unstable network connection.

npm cache verify this fixed this problem for me

the same issue tried all above all solutions but still same error

@Shreeyag29 it do be like that sometimes

Same error here trying to install some pre-edited bootswatch theme to work with.
2020-10-27T15_13_22_122Z-debug.log

That’s the log, also made a cache verify and such. Still not working.

Node v14.14.0
NPM 6.14.8
Windows 10 machine

Facing this error when running the command ‘npm outdated‘

npm ERR! cb() never called!

npm ERR! This is an error with npm itself. Please report this error at:
npm ERR! https://npm.community

ignore my previous comment about npm cache verify , i just got lucky while installing (1600-1700 packages)

this seems to have something with network state and/or network tools (bunch of errors while trying yarn install might be a hint); i’ve disabled little snitch and adguard also switched to cell hotspot, and installation worked (don’t have time to experiment further, deadline is tomorrow xD)

@kaznovac yeah i think it has something to do with network/firewalls and antivirus software, good thing it worked for you

I had the same issue when I was connected to a slow VPN, 4 or 5 time it errored.
Disconnecting from it and having a good network connection fixed it for me.

Hi guys, I had the same issue and I finally found the problem, the problem is the antivirus, I disabled it that worked.

Faced the same error. Was stuck with it for a long time.

My os is windows 10 pro.

This is how I got out of it :

Clear all the npm-cache first, and install the latest version of Node.
Uninstall the create-react-app globally using npm uninstall -g create-react-app in the Node terminal.
then run npx create-react-app

I don’t know why but the last two methods worked only when I deleted the logs first.

Hope this works for you.

I built my apps with Docker Compose, and each Nodejs service ended with an error: «npm error cb() never called!». I have tried everything: cache cleaning, reinstall, etc. The interesting thing is that everything works on my Macbook. So, I thought it must be something with a network or Windows. So, I decided to go via VPN, and it worked. I don’t know the exact problem it solves, but this thing worked for me.

man every time there’s a new comment here, it brings back the nightmare this problem has caused.

no answer at all

i face the same error when i want to create the my application

ERROR in /js/app
Module not found: Error: Can’t resolve ‘C:UsersELIAS MWITA NSONGODesktopprojectslaravel-studyingresourcesscssapp.css’ in ‘C:UsersELIAS MWITA NSONGODesktopprojectslaravel-studying’

🐞 [BUG] «npm ERR! cb() never called!» or «Exit handler never called» #417

Note: Please read this doc before filing a new issue.

The text was updated successfully, but these errors were encountered:

I think we have many reports of the same so these should all be duplicates.

Afaik this is resolved by force-clearing the cache and upgrading / updating to the latest npm version.

thanks @DanielRuf for linking all those ❤️

I guess we can check which version first introduced this (doing a small git bisect ) and check the stacktraces for similarities.

Following versions were mentioned in the issues:

Now trying to get a reproducible testcase.

Relevant changes in the past tolog this error: npm/npm#15716

Tests with a local npm 6.13.1 (on macOS):

@vue/cli : not reproducible
npm audit fix : not reproducible
plotly.js : not reproducible
expo-cli : not reproducible

So far it looks like this is caused by other errors which cancel the CLI too early.

I remember that we had this bug also on Ubuntu with the latest version and some packages.

I’m experiencing the same error trying to install a company project for development.
Microsoft Windows [Version 10.0.17134.1184]

Using NVM to switch instances of node/npm
node v10.14.2 (64-bit), npm v6.4.1
node v12.4.0 (64-bit), npm v6.9.0

project was generated with Angular CLI version 8.3.21

[NVM for Windows Setup, Ecor Ventures LLC, ‎Tuesday, ‎August ‎7, ‎2018 9:46:31 PM]

(note that must be nvm-windows; actual nvm doesn’t work on non-WSL Windows, and doesn’t distinguish 64-bit)

We’re getting this error intermittently in both local development and in our CI system. Happy to add any additional logging that might help. Attached the npm log from a run that just happened on my laptop on my mac — trying to npm install one of our private packages. Immediately re-running the command worked without issue.

❯ npm -v
6.13.4
❯ node -v
v13.5.0

Let me know if there’s anything I can do to help track this down, would like to kill the issue.

npm audit fix ( npm@6.9.0 / node@10.16.1 )
npm install ( npm@6.10.2 / node@12.8.0 )
sudo npm install -g npm ( npm@6.9.0 / node@x.y.z )
n/a likely npm i ( npm@6.12.1 / node@13.1.0 ) ( npm@6.12.0 / node@12.13.0 )

npm install ( npm@6.9.0 / node@10.16.1 )
vue create ( npm@6.2.0 / node@10.9.0 )

Thoughts as triaging:

Seems like there is an error while installing a package that causes this cb() never called! error.
There are 42 issues to triage.

cb() never called! Can’t update NPM or install new #442 original issue references a fix which references updating and cleaning cache to solve issue (updating fixes permissions), cache might indicate problem exists/existed in cacache or pacote

cb() never called! #451 seems to have same symptom but cause doesn’t seem to be within npm , though it does help point to an issue with while installing a package

I got same error. and FIXED IT.
I was trying to dockerize a nodejs project with a docker file. and package.json.
on my ubuntu machine there is no problem, but on CI/CD machine (centos,debian) almost fails to dockerize

Tried Steps:

clear node_modules
updating node version
updating npm version
centos
debian
docker with different versions
lots of configuration (npm install fetch-retries, timeouts . )

Here we will learn how to fix «npm ERR cb() never called» error in our nodejs application easily. This error is very common in any JavaScript frameworks and libraries like reactjs, vuejs too.

Reasons for the error

This error usually occurs

When we install too many node modules packages in our project and due to which sometime our package-lock.json file gets corrupt.
Or sometimes when updating our nodejs version to the latest one, it corrupts the package.json file.

Fixes for «npm ERR cb() never called» error.

To fix the npm err cd() error, i found this four solutions and it fixes my issue.

Solution 1: Clearing the NPM Cache

If the error occurs in local machine then clearing the cache fix the error.

So, first delete the package-lock.json file and then run the following command

and run npm install again to update the package-lock.json file

Solution 2: Upgrade npm version

If you are running on a npm version which is lower than what is required by the package you will get the error.

To upgrade your node version globally , run:

Soultion 3: Delete and Install node_modules folder

Delete package-lock.json file and whole node_modules folder and then reinstall everything by running the command:

Note: Do not delete the package.json file or npm install wont work.

Solution 4: Install the required node version

Sometimes when deploying our application on some online platform like heroku etc, we might get this error. It’s because they need a specific node version to work properly.

To fix we just need to specify the specific version in the package.jsonfile.

"engines": {
  "node": "12.x.x"
}

Once you have update your package.json file with correct version, you can deploy it.

I hope the above two solution works for you too. 😀

In this post, I will discuss solutions for a very common nightmare level issue faced by almost every node developer.

This issue generally appears while installing the npm packages for a new project setup or sometimes an existing one. The error that strikes and leave you in a head hitting situation reads like this:

npm ERR! cb() never called!

Error with npm itself

So we know this is some error with NPM itself and it’s been there for a long and not yet resolved.

Let’s have a look at various methods to overcome this issue and save numerous hours looking at other things.

How to resolve cb() never called! during npm install?

You can resolve this issue by following the various methods given below.

Method 1 – NPM Verify and Clean Cache

Method 2 – Delete package-lock.json and Node Modules folder

Method 3 – Install One Then Others Trick

Method 4 – If Error in NPM, use PNPM

Find detailed procedures below. Make sure you follow each step and I am making sure you leave this page with this issue resolved!

Method 1 – NPM Verify and Clean Cache

Run the following commands one by one to verify and clean npm cache from system-defined folders:

npm cache verify
 npm cache clean --force

Now try doing npm install

Method 2 – Delete package-lock.json and Node Modules folder

Simply delete the package-lock.json and delete the node_modules folder. Deleting the node_modules folder may take time so instead, rename it to something else like node_modules_old.

Now try running npm install

Method 3 – Install One Then Others Trick

Pick 2 to 3 package names from your package.json file and install them individually instead of npm install. For example;

npm install abc
npm install xyz

etc.

If it succeeds, it will create node_modules folder and package-lock.json and also confirm if you are able or not able to get a few of the packages downloaded from artifactory in your network.

Method 4 – If Error in NPM, use PNPM

Yes, you heard right, you can quickly install pnpm it is the best substitute for npm. It is more optimised and uses fewer resources and also uses less time to install the package when done again and again.

Step 1 – Install PNPM

You can follow the steps given here for multiple platforms. Using npm install globally as follows:

npm install -g pnpm

Step 2 – Do PNPM Install now

Now simply execute pnpm install in your folder.

Check more details here.

Now, your issue should be resolved with all packages installed.

Hope this was helpful…share which method worked in your case… Thanks.
