Error cannot find module ejs

Here is my complete error: Error: Cannot find module 'ejs' at Function._resolveFilename (module.js:317:11) at Function._load (module.js:262:25) at require (module.js:346:19) at View.

My source code is also very simple:

var express = require('express');

var app = module.exports = express.createServer();

// Configuration

app.configure(function(){
  app.use(express.bodyParser());
  app.use(app.router);
  app.use(express.static(__dirname + '/public'));
});

app.set('view engine', 'ejs');
app.set('view options', {
    layout: false
});

app.get('/', function(req, res) {
  res.render('index', {
    message : 'De groeten'
  });
});

app.listen(3000);
console.log("Express server listening on port %d in %s mode", app.address().port, app.settings.env);

In my folder, I have ejs installed in node_modules which I got using npm install ejs.
enter image description here so my question is.. what gives? What am I doing wrong so that node can’t find EJS when I clearly have it installed?

Thanks

I had this exact same problem a couple of days ago and couldn’t figure it out. Haven’t managed to fix the problem properly but this works as a temporary fix:

Go up one level (above app.js) and do npm install ejs. It will create a new node_modules folder and Express should find the module then.

Install express locally

(npm install express while in the project’s root directory)

Your project depends on both express and ejs, so you should list them both as dependencies in your package.json.

That way when you run npm install in you project directory, it’ll install both express and ejs, so that var express = require('express') will be the local installation of express (which knows about the ejs module that you installed locally) rather than the global one, which doesn’t.

In general it’s a good idea to explicitly list all dependencies in your package.json even though some of them might already be globally installed, so you don’t have these types of issues.

Way back when the same issue happened with me.

Dependency was there for ejs in JSON file, tried installing it locally and globally but did not work.

Then what I did was manually adding the module by:

app.set('view engine','ejs'); 

app.engine('ejs', require('ejs').__express);

Then it works.

I my case, I just added ejs manually in package.json:

 {
   "name": "myApp"
   "dependencies": {
     "express": "^4.12.2",
     "ejs": "^1.0.0"
   }
 }

And run npm install (may be you need run it with sudo)
Please note, that ejs looks views directory by default

I had the same issue. Once I set environment variable NODE_PATH to the location of my modules (/usr/local/node-v0.8.4/node_modules in my case) the problem went away. P.S. NODE_PATH accepts a colon separated list of directories if you need to specify more than one.

Install it locally rather installing it globally. Then your project may be run on any machine without any error.I think its better.

npm install express --save
npm install ejs --save

After you’ve installed Express V x.x.x
You need to choose an template view-engine. There are many really easy to learn. My personal go-to is EJS.

Other really great and easy to learn could be:

  • Handlebars
  • PUG (Former Jade)

To install EJS (And fix your error)
Run in root of your project:

npm install ejs

Or if you’re using Yarn:

yarn add ejs

Next you’ll need to require the module, so open up your file where you require express (usually app.js or server.js)

add below var express = require('express');

var ejs = require('ejs');

i had the same problem. So i did the following and it worked for me.

solution:

  1. run » npm init » in the project directory if not already done.
  2. install ejs and express as follows:

npm install ejs —save
npm install express —save

by doing so it creates the required dependencies in the package.json file

I had this problem. I debugged using node-inspector and saw that from the node_modules folder where the express source files were, ejs was not installed. So I installed it there and it worked.

npm install -g ejs didn’t put it where I expected it to despite NODE_PATH being set to the same node_modules folder. Prob doing it wrong, just started with node.

Reinstalling npm, express and ejs fixed my problem

This one worked for me,

  1. On your terminal or cmd -> Go to your apps directory,
  2. cd pathtoyourapp/AppName
  3. rerun your ‘npm install’
  4. rerun your ‘npm install express’
  5. rerun your ‘npm install ejs’

after that, the error was fixed.

After installing node express project you need to install the ejs or pug package for that

either you can try with node

npm install ejs 
npm install pug

or you can try with yarn

yarn add ejs
yarn add pug

globally or locally

STEP 1

See npm ls | grep ejs at root level of your project to check if you have already added ejs dependency to your project.

If not, add it as dependencies to your project. (I prefer adding dependency to package.json instead of npm installing the module.)

eg.

{

  "private": true,                                                                                     
  "scripts": {

  },

    "morgan": "~1.7.0",                                                                                
    "serve-favicon": "~2.3.0"

I think ejs template engine is not properly installed on your machine.
You just install the template engine using npm

npm install ejs --save

then include the following code in app.js

app.set('view engine', 'ejs')

kindly ensure that your dependencies in your package.json files are up to date. Try reinstalling them one at a time after also ensuring that your NPM is the latest version (up-to-date). It worked for me. I advise you to run npm install for the packages(thats what worked in my own case after it refused to work because I added the dependencies manually).

I ran into this problem after I forgot to install ejs before the first time I ran my app. For some reason ejs was not being seen after installing it later. I found a quick, clean, and effective solution to this problem which was to reinstall express by running npm uninstall express then npm install express in the local directory before restarting the server.

npm install ejs --save worked for me ! ✅

On goormIDE, I had this file configuration :

  • container
    • main.js
    • package-lock.json
    • package.json
    • node_modules
    • views
      • home.ejs

In my main.js file, I also had this route 

app.get("/", function(req, res){
res.render("home.ejs");
})

npm install ejs -g didn’t add the corresponding dependency within the package.json.
npm install ejs --save did. I executed the command line from the container directory. Manually it could have been added into the package.json with :
**

"dependencies": {
    "ejs": "^3.0.2",}

Cannot find module EJS #910

I’m getting the ‘Cannot find module EJS’ error when trying to render a page.

Installing EJS globally, or installing it a level above my app.js file fixes this issue. Here is a stackoverflow question from someone else who had the problem:

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

if you can require(‘ejs’) it in your app.js file express should be able to find it just fine

hmm it kinda looks like it’s using a globally installed express..

It’s a bit strange — I’ve tried requiring EJS from my app.js file and although it’s in the main node_modules folder the require now fails as soon as the app starts. Moving EJS back out to a node_modules a level above my app.js fixes it.

This is on a new machine so I haven’t installed Express or EJS globally.

looks global to me «/Users/shamoon/local/node/lib/node_modules/express»

that should be «/Users/shamoon/Sites/soldhere.in/node_modules/express»

Oh yeah I see what you mean — that’s not the error I submitted on stackoverflow, that was someone else who seemed to be having the same problem.

Here’s my stack trace:
500 Error: Cannot find module ‘ejs’

One point I’ve just thought of that may be applicable — I’m mounting a second Express app (api) within a main Express app (site)

hmm yeah that might have something to do with it, bottom-line is that if you can require() it in that app, express can get it, so that’s definitely the first thing to resolve

I’ve got: require(‘ejs’) and app.set(‘view engine’, ‘ejs’) — and I still get this error. For me, it was having a globally installed express. global express + any kind of ejs resulted in the module not being found when using render(). Locally installed both seemed to work.

This issue has been inactive for over 4 months so I’m closing it. If you think it’s still an issue re-open.

Open a new issues with complete information so we can better assist you. This issue is 6 years old and Express and things like ejs have changed a fair bit in that time.

Мой исходный код тоже очень прост:

В моей папке у меня установлены ejs в node_modules, которые я использовал npm install ejs . так что мой вопрос .. что дает? Что я делаю неправильно, так как этот узел не может найти EJS, когда он у меня явно установлен?

вы установили экспресс глобально? Если я правильно помню, у меня были проблемы при установке Express глобально и ejs локально. попробуйте также установить Express в папку вашего проекта или ejs в папку глобального модуля. — Philipp Kyeck

У меня такая же проблема. В итоге я удалил каталог node_modules и выполнил новую установку npm install -g. — Robert Walters

У меня была такая же проблема пару дней назад, и я не мог ее понять. Не удалось исправить проблему должным образом, но это работает как временное решение:

Поднимитесь на один уровень (выше app.js) и выполните npm install ejs . Он создаст новую папку node_modules, и тогда Express должен найти модуль.

npm install ejs -g может быть более чистым обходным путем. ( -g для глобальной установки) — Фаржер

При развертывании моего приложения в Openshift у меня была та же ошибка, и я заметил, что забыл добавить зависимость к ejs in packages.json . Теперь работает нормально ( npm install было выполнено автоматически при следующем перезапуске). — Бастьен Янсен

Я не думаю, что вы захотите установить node_module во всем мире я делал то же самое раньше, и когда вы развертываете, становится больно — налить код

Я просто добавил модуль express в качестве зависимости в свой файл package.json, и он начал работать. Поэтому убедитесь, что и ejs, и express упоминаются как зависимости. — Prateek

Очевидно, я поддержал основной ответ (э-э), но я также хотел поблагодарить @Stephen Bugs Kamenar за предложение (-g) глобальной установки. На самом деле я обманул и сделал и то, и другое (ленив меня), и это сработало сразу после перезапуска моего приложения. — Г-н Бенедикт

Установить экспресс локально

( npm install express находясь в корневом каталоге проекта)

Ваш проект зависит от обоих express и ejs , поэтому вы должны указать их как зависимости в вашем package.json .

Таким образом, когда вы бежите npm install в каталоге вашего проекта он установит оба express и ejs , Так что var express = require(‘express’) будет локальным установка экспресс (который знает о ejs модуль, который вы установили локально), а не глобальный, чего нет.

В общем, рекомендуется явно перечислить все зависимости в вашем package.json даже если некоторые из них могут быть уже установлены глобально, поэтому у вас нет проблем такого типа.

Я была такая же проблема. Как только я установил переменную среды NODE_PATH в расположение моих модулей (/usr/local/node-v0.8.4/node_modules в моем случае), проблема исчезла. PS NODE_PATH принимает список каталогов, разделенных двоеточиями, если вам нужно указать более одного.

ответ дан 20 авг.

Это очень важно, и его часто упускают, +1 тебе, Пит! — Javabeangrinder

У меня не было NODE_PATH env var, поэтому простой export NODE_PATH=. работал для моего проекта, у которого есть свои зависимости в собственном каталоге. Ваше здоровье — Грег

В моем случае я просто добавил ejs вручную в пакет.json:

И запустите Установка npm (может быть, вам нужно запустить его с SudoОбратите внимание, что по умолчанию ejs смотрит каталог просмотров.

Can’t resolve ‘ejs-html-loader’ #3

I does’t use EJS. Only src/index.ejs

In v0.10.0 got this error:

I try install this

And got another error

After installation, one more .

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

I’m having the same problem with ejs-html-loader .

I was comparing my code to Electrify and couldn’t figure out why Electrify can compile and I can’t. Guess it has to be, as you point out, something with the latest version of electron-webpack .

You don’t need this file anymore.

Anyway, error will be fixed.

You don’t need this file anymore.

So the logic in that file is now handled internally in electron-webpack ?

is now handled internally in electron-webpack?

I’ve noticed that index.html get generated automatically, but what I’ve been trying to figure out is how to get the title of the main window to show anything else than the npm package name.

to show anything else than the npm package name.

@develar A few days ago I raised this issue in the slack. When you create a BrowserWindow , title set from parameters, but then, it is overridden by the value from the tag.
I correctly understood that now there is no way to manage the template index.html if index.ejs don’t need anymore?

I will check this case. title param should win.

I correctly understood that now there is no way to manage the template index.html if index.ejs don’t need anymore?

index.ejs as in the original vue electron boilerplate is supported. Default template is used when no index.ejs If you want customise title — I will option for that.

Now productName option from electron-builder is respected.

Yes, it is strange, but title browserWindow option doesn’t change windows title.

@FantasticFiasco Perhaps you will be useful. In my case, I wanted to set the header from the main process and do not change it later. So I used this code

title option is ignored because html contains title and, logically, on page load new title is applied.

@develar I’ll give it a try this evening and will get back to you with the outcome. Thanks for putting the effort in fixing this!

I think, we should do not add title tag in the html template.

  1. title option doesn’t work — user need to know about page-title-updated trick.
  2. in the production mode (packed), title defaults to your app name (electron-builder correctly sets properties).

So, the only drawback, — in the development mode title defaults to Electron . But, often, you in any case explicitly set title to something app specific (app version, or project info, and so on).

@develar I trued. Window has «index.html» as title

@cawa-93 In my case removing title tag works as expected — title option is respected now. I am going to release this fix. Or do you mean that it doesn’t work for you (можно обсудить в слаке)?

I can not tell you in detail, because I did not test it in detail. But a few days ago, in search of a way to set and not change the title from the main process, I tried to use the index .ejs without a tag. After loading the window, the title was set as an «index.html». And I left in search of another solution.

I raised this issue in the slack. In the same place I was told the solution —
https://atomio.slack.com/archives/C044E597S/p1501517367608209

I’ve verified that version 0.10.3 fixes my problem, the title is no longer changed to the npm package name. Again, than you for all your help.

Crank up some music. Research shows that playing audio you like when you are weightlifting can assist you do more reps than
not hearing any tunes whatsoever or otherwise playing the
background music which you like. In addition, possessing earphones might help distract you from using a chat with others which will defer your workout.

It is extremely crucial that you stand correctly when you are performing standing up workout routines, for example over

I had this exact same problem a couple of days ago and couldn’t figure it out. Haven’t managed to fix the problem properly but this works as a temporary fix:

Go up one level (above app.js) and do npm install ejs. It will create a new node_modules folder and Express should find the module then.

Install express locally

(npm install express while in the project’s root directory)

Your project depends on both express and ejs, so you should list them both as dependencies in your package.json.

That way when you run npm install in you project directory, it’ll install both express and ejs, so that var express = require('express') will be the local installation of express (which knows about the ejs module that you installed locally) rather than the global one, which doesn’t.

In general it’s a good idea to explicitly list all dependencies in your package.json even though some of them might already be globally installed, so you don’t have these types of issues.

I had the same issue. Once I set environment variable NODE_PATH to the location of my modules (/usr/local/node-v0.8.4/node_modules in my case) the problem went away. P.S. NODE_PATH accepts a colon separated list of directories if you need to specify more than one.

I my case, I just added ejs manually in package.json:

 {
   "name": "myApp"
   "dependencies": {
     "express": "^4.12.2",
     "ejs": "^1.0.0"
   }
 }

And run npm install (may be you need run it with sudo)
Please note, that ejs looks views directory by default

Way back when the same issue happened with me.

Dependency was there for ejs in JSON file, tried installing it locally and globally but did not work.

Then what I did was manually adding the module by:

app.set('view engine','ejs'); 

app.engine('ejs', require('ejs').__express);

Then it works.

I installed ejs using command npm install ejs in express directory level and this solved my problem.

i have install express using steps mention in express guide http://expressjs.com/guide.html

Install it locally rather installing it globally. Then your project may be run on any machine without any error.I think its better.

npm install express --save
npm install ejs --save

After you’ve installed Express V x.x.x
You need to choose an template view-engine. There are many really easy to learn. My personal go-to is EJS.

Other really great and easy to learn could be:

  • Handlebars
  • PUG (Former Jade)

To install EJS (And fix your error)
Run in root of your project:

npm install ejs

Or if you’re using Yarn:

yarn add ejs

Next you’ll need to require the module, so open up your file where you require express (usually app.js or server.js)

add below var express = require('express');

var ejs = require('ejs');

i had the same problem. So i did the following and it worked for me.

solution:

  1. run » npm init » in the project directory if not already done.
  2. install ejs and express as follows:

npm install ejs —save
npm install express —save

by doing so it creates the required dependencies in the package.json file

I had this problem. I debugged using node-inspector and saw that from the node_modules folder where the express source files were, ejs was not installed. So I installed it there and it worked.

npm install -g ejs didn’t put it where I expected it to despite NODE_PATH being set to the same node_modules folder. Prob doing it wrong, just started with node.

I installed both: express and ejs with the option —save:

npm install ejs —save
npm install express —save

This way express and ejs are dependecies package.json file.

Reinstalling npm, express and ejs fixed my problem

This one worked for me,

  1. On your terminal or cmd -> Go to your apps directory,
  2. cd pathtoyourapp/AppName
  3. rerun your ‘npm install’
  4. rerun your ‘npm install express’
  5. rerun your ‘npm install ejs’

after that, the error was fixed.

STEP 1

See npm ls | grep ejs at root level of your project to check if you have already added ejs dependency to your project.

If not, add it as dependencies to your project. (I prefer adding dependency to package.json instead of npm installing the module.)

eg.

{

  "private": true,

    "express": "~4.13.4",                                                                              
    "jade": "~1.11.0",                                                                                 
    "ejs": "^1.0.0",                                                                                                                                                            
    "morgan": "~1.7.0",                                                                                
    "serve-favicon": "~2.3.0"                                                                          
  }                                                                                                    
}

STEP 2 download the dependencies

npm install

STEP 3 check ejs module

$ npm ls | grep ejs
[email protected] /Users/prayagupd/nodejs-fkers/musicpedia
├── [email protected]

Add dependency in package.json and then run npm install

    {
  ...
  ... 
  "dependencies": {
    "express": "*",
    "ejs": "*",
  }
}

I think ejs template engine is not properly installed on your machine.
You just install the template engine using npm

npm install ejs --save

then include the following code in app.js

app.set('view engine', 'ejs')

I have the same issue it resolve after installing the express in my project directory. previously i install it in global scope with -g option with npm install command.

In my case there was no silly syntax error, but same error arised.
I had installed ejs and ejs-mate globally. I installed it locally and found my error resolved.

kindly ensure that your dependencies in your package.json files are up to date. Try reinstalling them one at a time after also ensuring that your NPM is the latest version (up-to-date). It worked for me. I advise you to run npm install for the packages(thats what worked in my own case after it refused to work because I added the dependencies manually).

In my case it was a stupid mistake- it was a typo in the middleware. I wrote app.set('view engine', 'ejs.'); the dot caused the error. I installed ejs and express locally

Ensure all dependencies are installed. npm install

I was making a quick app for myself and I had forgotten to add express. Threw the above error.

I face same error for ejs, then i just run node install ejs
This will install ejs again.

and then also run npm install to install node_modules again.
That’s work for me.

I ran into this problem after I forgot to install ejs before the first time I ran my app. For some reason ejs was not being seen after installing it later. I found a quick, clean, and effective solution to this problem which was to reinstall express by running npm uninstall express then npm install express in the local directory before restarting the server.

npm i ejs --force

this worked for me

Installing express locally solved my same problem.
npm i express —save

i had the same issue and tried a few of the given solutions but it still didn’t work. all i did was to run the «npx yarn» command in the root folder of my project and that was it.

app.set('view engine', 'ejs')

and then in the terminal

npm install ejs --save

resolves the issue

In my case, I just uninstall then install ejs again.

npm uninstall ejs

then

npm install ejs

npm install ejs --save worked for me ! ✅

On goormIDE, I had this file configuration :

  • container
    • main.js
    • package-lock.json
    • package.json
    • node_modules
    • views
      • home.ejs

In my main.js file, I also had this route 

app.get("/", function(req, res){
res.render("home.ejs");
})

npm install ejs -g didn’t add the corresponding dependency within the package.json.
npm install ejs --save did. I executed the command line from the container directory. Manually it could have been added into the package.json with :
**

"dependencies": {
    "ejs": "^3.0.2",}

**

you must have

const ejs = require('ejs')
app.set('view engine', 'ejs')
