rust-analyzer failed to load workspace: "cargo" "--version" failed: program not found

Question

I have Rust installed using WSL2 Ubuntu I have alredy ran basic commands like hello world in rust so cargo is working. I wanted to download the rust-analyzer in VSCODE but I keep getting that error message from the title: rust-analyzer failed to load workspace: "cargo" "--version" failed: program not found

I tried ensuring all paths are correct, all vesions of extension and vscode and rust are up to date. several uninstall re-installs and rustup updates. Toolchain is using stable version. I have reviewed a lot of the other post about this accross all platforms but it seems I can not find the fix. It would be very helpful to get some guidance. Thank you!st

Answer 1

Remove the rustc and cargo provide by system package manager (e.g. apt).

Install them from offical rustup script instead.

[note]

I just encounter the same problem when using flatpak version of Lapce.

rust-analyzer failed to load workspace: "cargo" "--version" failed: No such file or directory (os error 2)

Answer 2

another good option is open your wsl, move to the project folder and type $ code . or $ code YOUR_PROJECT, then install rust-analyzer extension

Answer 3

The solution is to open folder as if in WSL.

• To do that you need to install this VS code extension called Remote development
• Than go to the green symbol in the bottom right corner and then select open WSL folder and open folder with your rust project or just open new WSL window

• The last step is to go to extensions and then search for rust-analyzer and hit install

More info regarding the development on WSL can be found here
