Node version not detected correctly on WSL2

[ghost]

I'm trying to install rust analyzer vscode extension from WSL2 (Ubuntu 18.04), but I get an error message about needing node > 10.x.

will run: code-insiders --list-extensions
Ignoring option list-extensions: not supported for code-insiders.
Error: install client

Caused by:
    Could not install the Visual Studio Code extension. Please make sure you have at least NodeJS 10.x installed and try again.

however I have node v12.13.1 in my Windows path and v13.3.0 in WSL.

Full output;

That sounds like a Code (--list-extensions works in 1.40), not node.js problem.

cc microsoft/vscode-remote-release#385

Not sure what's going on here, we probably need to either change our installation instructions, or to provide a better error message. The relevant code is here:

https://github.com/rust-analyzer/rust-analyzer/blob/ee904594af174866cfa10474fd8fd3f23580b6af/xtask/src/main.rs#L173-L234

I personally won't be able to look into this anytime soon

I see now I just missed the existing instructions for installing on vscode on a remote host. A relevant error message for someone using the wrong install method would be great though.

Presumably fixed in #3389.
