Uncaught exception error eperm operation not permitted - Исправление ошибок и поиск оптимальных решений проблем

I get this error in my app:

Error: EPERM: operation not permitted, open ‘C:Program Files
(x86)Full Menudbmain.json’

The app I have is built with electron-boilerplate. I am using this function to get the path to the root of the app:

path.dirname(process.execPath)

And this is the script that writes the file:

fs.writeFile(apath + '/db/' + elem + '.json', JSON.stringify(results)

I know what the problem is: permissions. But how could I get this working without running the app as an administrator?

asked Oct 29, 2015 at 16:16

For the benefit of searchers; I has this error. I added full permissions for Everyone as a test, but that didn’t fix it. The issue was that the file was set to readonly (by source control).

Unchecking the readonly option in the file properties fixed the issue.

On my Windows 10 machine, I encountered this error when running an old Node JS project. I think Node version 10.16.

In any case, it was trying to modify a dotfile in my project. Be sure that the file isn’t hidden on Windows. After unchecking the hidden option in the file properties pop up. Everything worked.

So to fix:

Right click file in Windows Explorer
Select properties
Uncheck Hidden
Click Ok
Re-run your command.

I face this issue when I was deleting a file/folder.

Solution:

Just restart your code editor/ terminal
Or
Restart your computer

answered Dec 3, 2019 at 5:32

If you are facing this issue on Windows 10, then please try the following:

Uncheck readonly options for the folder (if read-only reverts, login as administrator)
Open terminal as administrator (if you are facing this issue on terminal)
Switch off ransomware folder protection
Change chmod of the folder
Check if the folder is hidden or not
Disable antivirus protection (temporarily) and try this
Or move your project folder somewhere else, where antivirus ransomware protection is disable.

If nothing above works, then try the following:

Hope this would of help.

I think that you must change the permissions recursively to the file so the user executing your script can read / write this file.

in many programming languages, any permission related error may not

I had the same problem, when i tried to create and write to a file using NodeJS. I thought it had to do with my windows file/folder access permissions, but after restarting my computer and running the code again, I still got the same error.

However, this time around my antivirus gave me a pop-up message also, stating that it blocked permission for Node.exe to write or open files. So once I flagged Node.exe as safe for my anti-virus program (Avast).

It worked for me. Disabling my antivirus could’ve also temporarily fixed it, I guess.

I ran

After running that command,
When trying to run any npm commands on Windows OS I keep getting the below.

Error: EPERM: operation not permitted, mkdir 'C:Program Files (x86)Gitlocal'
at Error (native)

Have deleted all files from

C:Users<your username>.configconfigstore

It did not work.

Any suggestion ?

asked Jan 4, 2016 at 22:21

Running this command was my mistake.

npm config set prefix /usr/local

Path /usr/local is not for windows. This command changed the prefix variable at 'C:Program Files (x86)Gitlocal'

To access and make a change to this directory I need to run my cmd as administrator.

So I did:

Run cmd as administrator
Run npm config edit (You will get notepad editor)
Change prefix variable to C:Users<User Name>AppDataRoamingnpm

Then npm start works in a normal console.

This is occurring because windows is not giving permission to the user to create a folder inside system drive. To solve this:

Right Click

The Folder > Properties > Security Tab

Click on Edit to change Permissions > Select the user and give Full Control to that user.

The Problem I faced (In Windows Computer)

When I was trying to install a couple of npm packages I got the following error:

npm — EPERM: operation not permitted — while npm was trying to rename a file

Here’s my debug snippet for reference, if you’ve faced the similar problem:

After carefully checking out the answers from other users, I have created a detailed answer for the community

My Solution for the problem

Follow the mentioned steps

Right-click on the project folder
Go to properties -> Security Tab
Select Users -> Edit
In the Permission for Users section, Full control -> Give a check mark in Allow -> OK
Wait for Windows security to apply the new security rules
Click OK

Visualization of the steps

If you follow these steps and try to install npm packages again it will work properly.

Note: It’s a best practice to close and open up the command line again to experience the changes

If you getting this error in an IDE’s terminal/commands prompt, try delete node_modules, close IDE, and run the npm install command again.
The time when IDE started but still not completed its analysis of node_modules tree is a tricky moment, when packages installation may fail because IDE still scanning node_modules contents.

For those trying to update config

If having trouble updating your npm config, try instead running using the -g flag. This solved the issue on Win 10 for me after trying everything else.

npm config edit -g

I am able to update the config and changes are reflected everywhere. This may be due to running npm in an organizational scope.

Я получаю эту ошибку в своем приложении:

Ошибка: EPERM: операция не разрешена, откройте ‘C: Program Files (x86) Full Menu db main.json’

Приложение, которое у меня есть, построено на электронном шаблоне. Я использую эту функцию, чтобы получить путь к корню приложения:

И это сценарий, который записывает файл:

Я знаю, в чем проблема: разрешения. Но как я могу заставить это работать, не запуская приложение от имени администратора?

Предоставление полных разрешений директории, в которую он должен записать файл.
Как это сделать на машине с windows

В интересах поисковиков; У меня такая ошибка. Я добавил полные разрешения для в качестве теста, но это не помогло. Проблема заключалась в том, что файл был установлен на (системой управления версиями).

Снятие отметки с опции в свойствах файла устранило проблему.

1 Это текущее исправление, которое мне нужно сделать в данный момент. TFS + VS2015 помечает файл как , когда вы что-либо проверяете, и это нарушает мой сценарий сборки gulp. Пометка файлов как непрочитанных решает проблему, хотя это заставляет VS много жаловаться на файлы, в которых говорится, что существует . Будьте осторожны с этим, так как вы можете потерять изменения или даже файлы при получении последней версии.
Также была эта проблема, необходимая для использования Perforce (молитесь за меня), и она регулярно устанавливается только для чтения при синхронизации файлов. Щелкните правой кнопкой мыши> Снять отметку Только для чтения, устранена проблема.

Мне пришлось запустить командную строку узла от имени администратора, и это устранило проблему.

Я думаю, что вы должны рекурсивно изменить права доступа к файлу, чтобы пользователь, выполняющий ваш скрипт, мог читать / записывать этот файл.

https://fr.wikipedia.org/wiki/Chmod

Я решил проблему, изменив сценарий NSIS, чтобы я мог выбрать другую папку для установки.

Если у вас есть файл, который вы не можете открыть или изменить, смонтированный как том в докере, перезапуск докера должен решить проблему.

1 Этот ответ, похороненный среди тысяч страниц, которые я просматривал, буквально спас меня. Я терял рассудок. По какой-то причине мой глоток не удалял мою карту css, и часто перезагрузка ПК исправляла это, но на этот раз это не помогло. Я все перепробовал, и перезапуск Докера сработал. Не знаю, как и почему, но черт возьми!

Если вы используете Windows 10, необходимо отключить защиту от программ-вымогателей. Защита от программ-вымогателей предотвратит любые изменения папок и файлов. Вы можете отключить ее в Центре безопасности Windows. Смотрите скриншот ниже:

Даже если это решит проблему, это будет рискованно. Не облегчайте злоумышленникам возможность вымогательства вашей системы. Найдите другой способ.

У меня была ошибка, потому что я уже открывал файл раньше

Перезагрузка компьютера устранила эту проблему.

У меня тоже была эта проблема. Я использую TFS (или VSO, Azure DevOps и т. Д.) Для управления версиями. Я пытался скомпилировать из .scss в .css, но не смог открыть мой .css. Мне просто нужно было щелкнуть правой кнопкой мыши мой файл .css и проверить его на редактирование …

Я сталкиваюсь с этой проблемой, когда удаляю файл / папку.

Решение:

Просто перезапустите редактор кода / терминал или перезагрузите компьютер.

это не точный ответ, но может помочь:

я думаю если вы хотите или файл, который не существует, вы столкнетесь с ошибкой …

во многих языках программирования любая ошибка, связанная с разрешениями, может не означать напрямую фактическую проблему с разрешениями.

например, в папки (не файлы) должны быть удалены методом php , но если вы хотите сделать это с помощью , вы столкнетесь с неправильным предупреждающим сообщением, в котором говорится, что «разрешение отклонено»

На моем компьютере с Windows 10 я столкнулся с этой ошибкой при запуске старого проекта Node JS. Думаю, Node версии 10.16.

В любом случае, он пытался изменить точечный файл в моем проекте. Убедитесь, что файл не скрыт в Windows. После снятия отметки со скрытой опции в свойствах файла всплывают. Все заработало.

Итак, чтобы исправить:

Щелкните правой кнопкой мыши файл в проводнике Windows
Выбрать свойства
Снимите отметку Скрытый
Нажмите В порядке
Повторно запустите вашу команду.

Recently, when attempting to use the gulp command in the Terminal app, I saw an error message saying Error: EPERM: operation not permitted, uv_cwd. In this tutorial, you’ll learn how to solve this problem.

What causes this error

In my case, the below error appeared when attempting to run the gulp command inside my app project directory in the Terminal app.

$ gulp build
internal/bootstrap/switches/does_own_process_state.js:129
    cachedCwd = rawMethods.cwd();
                           ^

    at Argv (/usr/local/lib/node_modules/gulp-cli/node_modules/yargs/index.js:11:16)
    at Object.<anonymous> (/usr/local/lib/node_modules/gulp-cli/node_modules/yargs/index.js:6:1)
    at Module._compile (internal/modules/cjs/loader.js:1147:30)
    at Object.Module._extensions..js (internal/modules/cjs/loader.js:1167:10)
    at Module.load (internal/modules/cjs/loader.js:996:32)
    at Function.Module._load (internal/modules/cjs/loader.js:896:14)
    at Module.require (internal/modules/cjs/loader.js:1036:19)
    at require (internal/modules/cjs/helpers.js:72:18) {
  errno: -1,
  code: 'EPERM',
  syscall: 'uv_cwd'
}

This seemed strange to me because I had just used the gulp tool and everything was fine. Then I tried to use the bundle update command, thinking that this can be a hint to localize the problem.

$ bundle update
shell-init: error retrieving current directory: getcwd: cannot access parent directories: Operation not permitted
Traceback (most recent call last):
	9: from /usr/local/bin/bundle:23:in <main>
	8: from /Library/Ruby/Site/2.6.0/rubygems.rb:294:in `activate_bin_path'

/Library/Ruby/Site/2.6.0/rubygems/bundler_version_finder.rb:85:in pwd': Operation not permitted - getcwd (Errno::EPERM)

The error appeared again, but now the error message is self explanatory. It saying that the shell-init cannot access parent directories, and this is because error retrieving current directory.

In my case, this makes sense because I used the Finder to delete my app project catalog and restore it from the backup after trying new things and changed my mind to keep them. Facepalm >_<

Now we know what caused this error.

How to solve it

Once we know what is causing the gulp run to fail, we can use it to solve the problem. It is a really easy process. To solve this problem, we just need to re-enter into our app project directory. Now, step by step guide.

In the Terminal app, type the following command and press the Enter key to go up one level in the directory.

Now, type the following command and press the Enter key to navigate to your working directory (in this example the my_app_dir catalog is used).

Important! In my case the working directory is the catalog of my app project called my_app_dir where the problem has occurred. Change the command above to suit your case.

Conclusion

That’s it, you’re done. Now the gulp should run without the Error: EPERM: operation not permitted, uv_cwd error. So simple isn’t it?

If you are having trouble fixing this problem with the instructions above, but are being able to solve this problem with any another method please describe it in the comment section below. Thanks!

I hope this article has helped you learn how to fix the Error: EPERM: operation not permitted, uv_cwd error. If this article has helped you then please leave a comment

Thanks for reading!
