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 rust-lang/rust#53610):

[jens1o]

Is there anything I can do?

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

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:

[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 #641 (comment)

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.

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.
