Rls: rustup update warning says component rls-preview-x86_64-pc-windows-msvc was not found

[FrankvdStam]

I'm trying to use the VS code rust plugin, it says RLS server can't be started. I dug around and found this in this repositories readme:
rustup component add rls rust-analysis rust-src

Which tells me:
error: toolchain 'stable-x86_64-pc-windows-msvc' does not contain component 'rls' for target 'x86_64-pc-windows-msvc'

I've followed this issue: https://github.com/rust-lang/rustup.rs/issues/1184
I did also have 2 rustc's installed because I previously used the installer. Resolved this issue by deinstalling one version and keeping the rustup version.

Then when running rustup update I noticed multiple components couldn't be found (including RLS).

What am I doing wrong?
Is this the right repo for this issue?

[FrankvdStam]

I figured I'd try a clean install since I had previously used the installer (pre-rustup).

Uninstalled rust entirely:

C:\>rustup self uninstall


Thanks for hacking in Rust!

This will uninstall all Rust toolchains and data, and remove
%USERPROFILE%\.cargo/bin from your PATH environment variable.

Continue? (y/N) y

info: removing rustup home
info: removing cargo home
info: removing rustup binaries
info: rustup is uninstalled

C:\>where rustc
INFO: Could not find files for the given pattern(s).

C:\>where rustup
INFO: Could not find files for the given pattern(s).

Reinstalling rust (did not add rls):

Welcome to Rust!

This will download and install the official compiler for the Rust programming
language, and its package manager, Cargo.

It will add the cargo, rustc, rustup and other commands to Cargo's bin
directory, located at:

  C:\Users\f.stam\.cargo\bin

This path will then be added to your PATH environment variable by modifying the
HKEY_CURRENT_USER/Environment/PATH registry key.

You can uninstall at any time with rustup self uninstall and these changes will
be reverted.

Current installation options:

   default host triple: x86_64-pc-windows-msvc
     default toolchain: stable
  modify PATH variable: yes

1) Proceed with installation (default)
2) Customize installation
3) Cancel installation

Rust is installed now. Great!

To get started you need Cargo's bin directory (%USERPROFILE%\.cargo\bin) in
your PATH environment variable. Future applications will automatically have the
correct environment, but you may need to restart your current shell.

Press the Enter key to continue.

Adding RLS:

C:\>rustup component add rls rust-analysis rust-src
info: downloading component 'rls'
info: installing component 'rls'
info: downloading component 'rust-analysis'
info: installing component 'rust-analysis'
info: downloading component 'rust-src'
info: installing component 'rust-src'

Victory!

The issue is resolved for me, I'll leave this open so that somebody can decide if any actions should be taken.

I'd guess rustup got into a dodgy state, maybe a failed component install? I'd ask at rust-lang/rustup.rs if you wanted to investigate further.

[FrankvdStam]

I don't think it's worth anybody's time to investigate unless this happens a lot, in that case they already know about it.

I was surprised the installer didn't install this and assumed it was supposed to but gauging your reaction I was mistaken.
