Vscode-rust: Unable to install in VSCode 1.44.0

[cwaldren]

I have a brand new install of VSCode 1.44.0.

I attempted to install the Rust (rls) extension, but it fails with an error:

Error: the task 'Rust: Installing `rust-analysis`' neither specifies a command nor a dependsOn property. The task will be ignored. Its definition is:
{
    "type": "shell",
    "id": "shell,rustup component add rust-analysis --toolchain stable-x86_64-apple-darwin,",
    "problemMatcher": [],
    "label": "Rust: Installing `rust-analysis`"
}

I encountered this on Linux too. I downgraded to use VSCode 1.43, installed the extension successfully and then upgraded back to 1.44 without issue.

FWIW I had the same issue and manually ran rustup component add rls rust-analysis rust-src. When I opened VSCode again the extension seemed happy to use what I had installed.

can confirm it fixes the problem on Manjaro and vscodium

I have the same problem on Manjaro Linux, had to manually install the rust-src and rls components.
This happens when one of the three components is already installed in the system, I do not have enough experience with VScode extensions to propose a PR but the problem lies somewhere in the installRlsComponents function.

Fixed with rustup component add rls rust-src

[faisalr]

it needs rust-src to go to definition

I had the same issue and setting "rust-client.rlsPath": "rls" in VScode's settings.json resolved the issue.

Fixed in https://github.com/rust-lang/rls-vscode/commit/800a04afd2629146ccc18013ab36f978705d20cf, released a 0.7.2 with the fix. It seems that this has regressed in the newest VSCode.
