Vscode-rust: Couldn't start client Rust Language Server

Created on 13 Nov 2019 · 4Comments · Source: rust-lang/vscode-rust

I'm using rust 1.39.0 and installed it using rust version manager.

Now in vscode, I see the below error. Do I need to specific the rust path since the rust compiler or binary localtion would be different when installed using rust version manager.

Error
Couldn't start client Rust Language Server

I got the same problem on macOS. I checked which rustup using $ sh, $ bash and $ zsh. Rustup is always found under /Users/user/.cargo/bin/rustup. So it does not seem to be a $PATH problem. rls is also found /Users/user/.cargo/bin/rls.

UPDATE:
I solved this problem by explicitly setting "rust-client.rustupPath": "/Users/user/.cargo/bin/rustup".

This is somethong to with /bin/sh and the rustup can't be found in the $PATH.

Thanks to @eratio08 's comment, I also fixed this issue by going to ~/Library/Application Support/Code/User/settings.json and explicitly adding "rust-client.rlsPath": "/Users/NathanielRuiz/.cargo/bin/rls".

(You can also do this in Ctrl + Shift + P -> Preferences: Open User Settings)
