WSL2 - VSCode's shell command `code` no longer working in Linux terminal

I am very new to Linux and WSL overall. I was able to use code . to open my current directory in VSCode, but after deleting something that I do not remember it just doesn't work anymore. I put in the command and it just hangs there.

I have deleted my Ubuntu-20.04 instance and recreated it, but still it will not work. Also checked my $PATH and it seems to be there.

Also, the add shell command in VSCode does not come up, so I can't uninstall and reinstall the shell shortcut.

Anyone have any idea?

whereis and which

drewbie@drewbie:~$ whereis code

After doing what @NotTheDr01ds said in the thread below

I ended up getting it to work in the end. I believe it was the following that fixed it.

1. Go to your Terminal and delete your settings.json file. You make wish to save a backup first.

2. You are going to ctrl-a, delete it all, then SAVE THE FILE.

3. Very important step. When you go back to your Terminal, click SAVE in the bottom right corner.

4. Now, this is not fun, but we are going to unregister Ubuntu-20.04 from the powershell.

   Note: This is a destructive operation, and all data inside the WSL instance's filesystem will be lost. Again, before this step, you may wish to take a backup first with wsl --export Ubuntu-20.04 <backup-filename.tar> to be safe. When you are ready, from powershell, write wsl --unregister Ubuntu-20.04 or whatever your Distro is.

5. Restart your computer!!!

6. When your computer turns back on, you are going to re-install your distro and set it as default. wsl --install -d <Distribution Name>

7. Go through the setups, then all I did was code . and got the interaction below. It now works for me.

drewbie@drewbie:~$ ls

None of the reasonable solutions for this problem worked for me on a fresh laptop. The root cause turned out to be the order I performed my setup in.

My error: Prior to launching code I had setup the /etc/wsl/conf file to append the Windows Path to the wsl Path as false. These /mnt/c/Windows/paths can cause issues when doing various development tasks, but apparently they are needed initially for code to work.

[interop]
appendWindowsPath = false

So, when I went to launch code . within wsl it didn't know where to find it, as a result.

Fix:

Allow the windows paths to be appeneded

sudo nano /etc/wsl.conf

[interop]
appendWindowsPath = true

Exit out of wsl and then shut it down wsl --shutdown

Get back into wsl and launch code code .

It should install.

Optional:

You can then remove the windows paths from the configuration file once more and add the path in the ~/.bashrc file:

export PATH="/mnt/c/Program Files/Microsoft VS Code/bin:$PATH"
