[Question] Couldn't start client Rust Language Server

[SangwooJung98]

Although I installed Rust, codell at vscode while connected to ssh server and rustup to my laptop, I'm still getting same error message everytime I try to build the atomic.rs file.
I tried reconnecting the ssh server, deleting the .vscode-server folder but there's no difference.

My development environment is windows10.
Is there anyone who figured out a solution for this problem??

• You should install codelldb/rustup/rls at the server.
• Open a terminal ([Question] How can I download (and apply) crossbeam? #47), install rustup, and run rustup component add rls.

I tried the solution, but it does not work.
I installed codelldb and rust vscode extensions on the server, and ran rustup component add rls to install rls.

I found the reason why. Check this issue on rust vscode extension github.
rust-lang/vscode-rust#814

Hello. Can I ask if you managed to get it to work? I read the issue but I do not think we can edit setting.json on the server. I instead tried what was mentioned here rust-lang/vscode-rust#620, but this did not resolve the issue.

1. Ensure that you have ~/.cargo/bin/rustup.
2. Ensure that your ~/.profile contains following line:

   . "$HOME/.cargo/env"

   This also works:

   export PATH="$HOME/.cargo/bin:$PATH"

3. Create a file ~/.bash_profile with following line:

   source ~/.profile

4. Kill the vscode remote session and restart.

This way, vscode will read the PATH set in ~/.profile without changing bash's behavior.

Reference

• remote-ssh: .profile not sourced for bash shells, only .bashrc? microsoft/vscode-remote-release#83 (comment)
• bash man page:

  When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable.

This solved the issue. Thank you very much!
