Could not install RLS component (rls-preview)

[jdferreira]

Version of VSCode: 1.17.0
Version of the extension: 0.3.1
OS: Ubuntu 16.04

Description:
I cannot start the RLS. I get the following error when I start vscode (or when I reload the window):

• RLS not installed. Install?

When I clicked Yes, I got:

• Couldn't start client Rust Language Server
• Could not install RLS component (rls-preview)

I reinstalled the extension, but the problem persists.
I see in the Changelog that there was a change on how RLS detection is performed. Could this be related?

Output of the "Rust logging" channel (the selection box shows "Rust Language Server" and not "Rust logging", but I guess that's what you mean?):

[Error - 2:25:52 PM] Starting client failed

Just a quick note to say that the same thing happens with Windows.

[jdferreira]

Never mind; all I had to do was update rust nightly and install the (new?) rls-preview component.
I'm closing the issue.

Thanks.

Facing the same issue, cannot install rls-preivew:

error: could not find rls-preview in registry https://github.com/rust-lang/crates.io-index

@Yanpas see: rust-lang/vscode-rust#181 (comment)

What a mess. Why is extension depends on buggy nightly toolchain, what's the problem with using stable by default? I will be okay with using outdated but at least working copy of rls.

Now it prints 'rls is not found'. Total voodoo magic

According to readme we should switch to https://github.com/rust-lang-nursery/rls-vscode which surprise doesn't work too.

PS Nothing personal, I'm just raged with losing 2 hours on toolchain setup.

[AndreasHassing]

@Yanpas I feel your pain 😄. Also currently working on getting the toolchain to work, and I thought I would drop in and guide you to what I've learned so far 😃.

I've ran rustup component add rls-preview --toolchain nightly and it seems to work

[jtremback]

Getting

$ rustup component add rls-preview --toolchain nightly
error: toolchain 'nightly-x86_64-apple-darwin' does not contain component 'rls-preview' for target 'x86_64-apple-darwin'

[Cristian-Malinescu]

Also getting
$ rustup component add rls-preview --toolchain nightly error: toolchain 'nightly-x86_64-unknown-linux-gnu' does not contain component 'rls-preview' for target 'x86_64-unknown-linux-gnu'

[Rick-van-Dam]

Doesnt work on windows either:
$ rustup component add rls-preview --toolchain nightly error: toolchain 'nightly-x86_64-pc-windows-msvc' does not contain component 'rls-preview' for target 'x86_64-pc-windows-msvc'

Why doesnt it use stable?

Same problem here.

Found my way here after uninstalling from brew and reinstalling via rustup to see if I could get this this working. No dice.
How do you re-open an issue?

[paulevans]

See that #369
and #370
are related to this. Also about three weeks old at this point.

Okay this plug-in is pretty cool about configuration.
Add this to your user settings and pull from beta rather than nightly

    // Rust channel to install RLS from.
    "rust-client.channel": "beta"

so your entire settings might look something like

// Place your settings in this file to overwrite the default settings
{
    "workbench.colorTheme": "Visual Studio Dark",
    "window.zoomLevel": 1,

    // Rust channel to install RLS from.
    "rust-client.channel": "beta"
}

... if you've not configured code much yet.
