Rls: toolchain 'nightly-x86_64-unknown-linux-gnu' does not contain component 'rls'

[Doaxan]

After regular rustup update

I get this:

$  rls
error: toolchain 'nightly-x86_64-unknown-linux-gnu' does not have the binary `rls`

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

nightly-x86_64-unknown-linux-gnu installed - rustc 1.22.0-nightly (3c96d40d3 2017-09-28)

I have almost exactly the same error but with msvc:

error: toolchain 'nightly-x86_64-pc-windows-msvc' does not contain component 'rls' for target 'x86_64-pc-windows-msvc

[protomors]

Component "rls" was recently renamed to "rls-preview". Probably this is the reason for your problem. I just reinstalled rust completely and added "rls-preview" component. Now everything works.

Probably reinstalling rust was not necessary and simply adding "rls-preview" to updated toolchain should work.

[Flashs]

Had the same issue and using rls-preview fixed this for me too.

Yes, the rls component is renamed to rls-preview, however, the binary should still be called rls. You can change the name as a configuration option in VSCode (rust-client.rls-name). I'll make the new name the default, ASAP.

[leshow]

I had this issue too. I do have a binary called rls, but the vscode extension must look for component rls instead of rls-preview

[zanjs]

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

Change as follows

rustup component add rls-preview --toolchain nightly

[nrc]

Is this with the latest VSCode extension? If you have v0.3.0, this should be addressed.

Seeing same here:

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'

[Xanewok]

Try running rustup update first and see if that helps. I can confirm it
works on Windows with that specific toolchain for me.

Okay wierd, that fixed it but "rustup self update" didn't.

One thing I was was the old rls getting removed, maybe that's what's happening.

[Xanewok]

VSCode extension 0.3.1 also detects the new rls-preview component and it should be available to all the toolchains now, so I'm gonna close it.

Still seeing the issue on Windows:

@surferjeff This comment worked for me.

These are the commands I ran

rustup update beta
rustup component add rls-preview --toolchain beta
rustup component add rust-analysis --toolchain beta
rustup component add rust-src --toolchain beta

Then in VSCode I set "rust-client.channel": "beta" in my settings.

[ultramancool]

@surferjeff Looks like some recent nightlies haven't included rls for some reason.

https://www.reddit.com/r/rust/comments/7hkxez/how_to_check_rls_is_present_before_updating/

@golf1052 is suggesting using the beta... which may work for some, but will not necessarily contain the latest features.

[jasonwilliams]

This has stopped working for me the past week, i'm guessing its related to what you said @ultramancool I will try beta for now and see if that works

What teh...

C:\Users\User>rust-gdb

Guys seriously
We dont need tools for fighting with tools itself but for make things.
Where I can find the list af ACTUAL COMPONENTS NAME ?
