VS Code: NoPermissions (FileSystemError): Error: EACCES: permission denied - visual-studio-code

Question

I'm trying to save a file called app.js on a folder called js.
Vs Code pop up this:
Failed to save 'app.js': Unable to write file 'vscode-remote://wsl+ubuntu-18.04/js/app.js'
(NoPermissions (FileSystemError): Error: EACCES: permission denied, mkdir '/js')
I tried:
sudo chown -R user /mnt/c/Users/myUser/Documents/myFolder/proyectFolder
but I still can't save this file.

Answer 1

Try this, fixed it for me
sudo chown -R username path
Example:
sudo chown -R emanuel /home/emanuel/test/

Answer 2

In the SSH terminal:
Recommended :
sudo chmod -R 777 folder_name_where_your_file_exists
or
sudo chmod -R 755 folder_name_where_your_file_exists

Answer 3

this works for me
sudo chown -R $USER:$USER /home/

Answer 4

TLDR;
If you're using a docker container, avoid making files from within the container because the owner and group permissions may cause problems with your editor (in my case VS Code)
I was running docker container for a Django project from Windows Terminal and using VS Code to edit my code.
It is a Linux file (since everything in Linux is a file) permission problem that arises because the files don't have proper user and/or group permissions. So VS Code tries to tell us that.
The problem I found only happened when I created files from within my docker container.
I would run docker exec ... bash
make new files using touch /path/to/file from the container bash
then try to edit those files on VS Code (say urls.py) only to get the scary permissions error preventing the file from saving.
I suspect that making files from within the container embellishes those files with different owner and group settings than your system would default to if you just ran the commands locally (not in the container).
Changing the file permissions with chown -hR and chgrp -hR would do the trick but to avoid the error altogether I stopped making files from within the container.

Answer 5

Try activating polling:
This worked for me during I tried using wsl.

Answer 6

The below is for individual file:
sudo chown yourUserNAme filename
For an entire directory it will be (when you write ls to terminal, you should see your directory to execute this command):
sudo chown yourUserNAme dirName
For recursive (i.e files and folders inside a folder):
sudo chown -R yourUserNAme dirName
Note: yourUserNAme is, if you do pwd under any Documents, you will see the path: /home/jhon/Documents. Here user is jhon.

Answer 7

Run VS Code as administrator and it will fix the problem.

Answer 8

Install the extension Save as Root in Remote SSH in VS code.
While saving press Ctrl + Shift + P.
This open the command palette.
Search Save as Root

Answer 9

It is a Linux user permissions problem.
you should use the command:
sudo chown -R $USER:$USER.
