Rls: Cannot install rls (extension unusable)

[jens1o]

Nightly exclued the block from rls-preview to build rustc without it, and now the extension stopped working?

It is asking me to install the Service.
Then this happens:

Log:

[Error - 10:09:40 AM] Starting client failed
Error: Error starting up rls.

Hmm, I think the RLS is missing from today's nightly, but it shouldn't be renamed (and Rustup should not install the nightly update unless you force it to). Do you have the output from when you ran rustup update?

[Xanewok]

It's true, nightlies did not ship with RLS today (waiting for https://github.com/rust-lang/rust/pull/53610):

[jens1o]

Is there anything I can do?

No, @nrc I didn't have the output of it anymore.

[urschrei]

Confirming that nightlies got built without rls-preview for some reason. I just updated on x86_64-apple-darwin, and it was removed. Output below:

  nightly-x86_64-apple-darwin updated - rustc 1.30.0-nightly (63d66494a 2018-08-23)

[o01eg]

Is it possible to prevent rustup from updating if rls isn't available?

[Xanewok]

It was that way before, not sure why the nightlies were released without RLS.
For now you can use the workaround from https://github.com/rust-lang-nursery/rls/issues/641#issuecomment-415700561

Also experiencing this. Output from rustup update:

The output ends abruptly because I tried to cancel it. It was already too late though so I currently don't have a working RLS.

[dergroncki]

Same happens to me:

[h-michael]

Now, nightly(1.30.0-nightly (39e6ba821 2018-08-25)) build has RLS.
If you run rustup update nightly, you can add RLS.

[sunjay]

Yup! Confirmed! I was able to get it to work. The latest version is 39e6ba821 2018-08-25 exactly like you said. :)

You may have to run the following after rustup update in order to get back the right components:

rustup component add --toolchain nightly rls-preview rust-analysis rust-src

[jens1o]

Works for me again, too.

[jntrnr]

This appears to have broken again with the latest nightly:

C:\Source\gatherer>rustup update
info: syncing channel updates for 'nightly-x86_64-pc-windows-msvc'
info: latest update on 2018-08-29, rust version 1.30.0-nightly (7061b2775 2018-08-28)
warning: component 'rls-preview' is not available anymore on target 'x86_64-pc-windows-msvc'

[razor950]

It is broken only because rls and a few other tools couldn't be compiled for that nightly.

https://rust-lang-nursery.github.io/rust-toolstate/ <- shows you if everything for that nightly is fine

[jntrnr]

@razor950 At least as I understand it nightlies shouldn't be available if the RLS isn't included (as mentioned earlier in this thread)

[razor950]

ah, that would make sense but I've had it happen a few times already so I wasn't sure what the norm was.

Thanks for the clarification and hopefully it does get fixed soon, I'll rollback my nightly for now though.

[bertbeck]

I'm having the same issue today:

[GabrielMajeri]

@bertbeck This will happen occasionally, when Rust upstream changes break RLS.

This is the intended behavior. Instead of silently removing the tools you want, rustup will warn you they aren't available.

Simply try updating again sometime later, after the components get fixed. Use update --force if you want to update and lose RLS/clippy/rustfmt.

[0b01]

For those failing rustup update because of rls-preview, run rustup component remove rls-preview then run rustup update.

[AN3223]

For those failing rustup update because of rls-preview, run rustup component remove rls-preview then run rustup update.

Just want to add that removing rls-preview this way fixed my problem with rls being unavailable for download.

[leshow]

@AN3223 note that this will install the current nightly, but you won't be able to install RLS for nightly again until it's fixed. So you'll have nightly rust without RLS

[siman]

Current solution:

rustup toolchain install nightly-2019-01-15
rustup default nightly-2019-01-15
rustup component add rls-preview rust-analysis rust-src --toolchain nightly-2019-01-15

[henryboisdequin]

Does anyone know a solution for this in 2021?

[hbriese]

• Find the latest nightly version that rls still builds on using https://rust-lang-nursery.github.io/rust-toolstate/
  It'll be 1 day prior to the "in this state since" date - assuming it's failing.
  At the time of this post that version is nightly-2021-07-05

• Download the latest version of nightly that rls still builds on, and override your project's rust version

rustup toolchain install nightly-2021-07-05
rustup override set nightly-2021-07-05-x86_64-unknown-linux-gnu
rustup component add rls rust-analysis rust-src
