WSL：Windows 没有权限写入新的用户文件

Question

I have Ubuntu 20.04 with WSL2 and created a new user with sudo privileges:

sudo adduser newuser
sudo usermod -aG sudo newuser
su - newuser

Windows does not seem to have permission to write in the new user folder. Here with Visual Studio Code:

touch test.txt
code test.txt

and then writing something and trying to save will ask me to try and do it as admin, which I do and then get this error message:

Failed to save 'test.txt': 
Command failed: "C:\Users\<username>\AppData\Local\Programs\Microsoft VS Code\bin\code.cmd" --file-write "c:\Users\<username>\AppData\Roaming\Code\code-elevated-pdtmzg" "\\wsl$\Ubuntu\home\newuser\test.txt"
Error using --file-write: EPERM: operation not permitted, open '\\wsl$\Ubuntu\home\newuser\test.txt'

Here is the result of ls -all with the new user work:

Here is the result of ls -all with the default user hellmers:

Here are the groups for the users. I also tried adding work to the hellmers group:

The only way I manage to get it to work is to give others write privileges through sudo chmod o+w <file>, which shouldn't be necessary?

Answer 1

You seem to be running into this issue. Namely, VSCode always runs as the default user in a WSL session.

You should be able to confirm this with a simple whoami in the VSCode terminal. Even though you started it from the work user, it will likely be running as hellmers.

For your particular use case, I would think, you could give your hellmers user access to the work user folder. Seems to work for me:

sudo usermod -aG work hellmers
chmod -R g+wrx /home/work

If you really do need to run VSCode as用户work，根据 Github 问题，你需要更改默认WSL 实例的用户。受到推崇的实现此目的的方法是创建一个具有以下内容的/etc/wsl.conf(as )：sudo

[user]
default=work

然后停止 WSL 实例wsl --terminate <distroname并重新启动。

work此时VSCode 应该以用户身份运行。

这既不美观也不方便。但如果您必须以其他用户身份运行 VSCode，则需要将该用户设为 WSL 实例的默认用户。

另一个可能的替代方案是设置单独的 WSL 实例，一个使用hellmers默认，另一个使用work。根据需要保留多个“实用”WSL 实例并没有错。
