Vscode-rust: RLS and Rustup errors on WSL

[tbremer]

Using Version 0.6.1 I am getting the following errors when opening any .rs file:

1. "Couldn't start client Rust Language Server"
2. "Rustup not available. Install from: "

The only setting I have selected is: Rust-client: Use WSL which is checked, and that option is only set in the Remote settings.

Is there some setting or configuration I am missing?

Here is a complete dump of my console:

To Install the RLS run this command rustup component add rls rust-analysis rust-src

Then add this to your settings :

  "rust-client.useWSL": true,
  "rust-client.revealOutputChannelOn": "info",
  "rust-client.rustupPath": "~/.cargo/bin/rustup"

Close and ReOpen vscode and it should work

We deprecated the WSL support in-extension, please try out the Remote - WSL extension. This, together with #612 (to be released in the next version), should fix the issue here.
