Can't find rustup

[robinst]

Version of VSCode: 1.12.1
Version of the extension: 0.3.14
OS: Mac OS

Description: I get the "You do not use Rustup. Rustup is a preffered way to install Rust and its components" message. But I have rustup installed. Not sure where to configure it to fix it. Output:

$ rustc --print=sysroot
/Users/rstocker/.multirust/toolchains/stable-x86_64-apple-darwin
$ where rustup
/Users/rstocker/.cargo/bin/rustup
$ where rustc
/Users/rstocker/.cargo/bin/rustc

Thanks for your help!

Output of the "Rust logging" channel:

DEBUG: handleMissingRls: Rust is either not installed or installed not via Rustup

@robinst,
Rustup stopped using .multirust a long time ago.
I haven't thought someone still uses this.
Currently you can configure it yourself:
Start code with RUSTUP_HOME=/Users/rstocker/.multirust.
It should help.

Weird, I have the newest version of rustup. I guess it has some special handling to keep installing into the same directory.

I'll try wiping it and reinstalling rustup and see which directory it ends up in. Thanks!

[kosta]

As far as I know, .multirust still exists for legacy reasons and is part of rustup. It should just be a symlink to .rustup, anyway. You can verify with ls -lha ~/.

Having the same problem with a freshly installed Rust

rustc --print=sysroot
~/.rustup/toolchains/stable-x86_64-apple-darwin

[KalitaAlexey]

@JonasFromell,
Now it doesn't work because the stable toolchain is used.

[robinst]

Freshly installed rustup now, still doesn't find it:

$ rustc --print=sysroot
~/.rustup/toolchains/stable-x86_64-apple-darwin

[KalitaAlexey]

@robinst,
You use the stable toolchain.
Make rustup default nightly.

[robinst]

Tried switching to nightly, still get "You do not use Rustup. Rustup is a preffered way to install Rust and its components".

[KalitaAlexey]

Post what the "Rust Logging" output channel says if you start the extension and the nightly is used.

[jfromell]

Switched to nightly, still got the message. But after a few restarts of VSCode the message disappears. Same thing again when i did an rustup update today. Messaged appeared on first startup of VSCode but disappeared when i restarted it.

[robinst]

So I think I know what the problem was for me: ~/.cargo/bin needs to be added to the PATH in ~/.profile. I just had it set in my zsh config files, but that doesn't get picked up by the session.

Maybe vscode-rust could check ~/.cargo/bin directly if it doesn't find rustup in the PATH?

[KalitaAlexey]

@robinst,
No, it will not.
I am sorry, but this is an specific case which I don't want to handle via the extension.

[wagenet]

@KalitaAlexey It does seem like there should at least be some documentation on how to solve this issue. Telling people they don't have Rustup installed when they know they do is problematic. Maybe a better message would also be to say "can't find rustup".

[KalitaAlexey]

@wagenet,
I am working on it.
I didn't thought a lot of people would have this problem.
I expected that I would have time to implement installing Rustup and etc.

[varkor]

Is this issue supposed to be fixed? I still get the banner every time I open Visual Studio Code, despite rustup being installed.
This might be the same issue as #242.

[willmurphyscode]

I also still get this banner every time. Does this affect everyone running on a Mac?

[jeremiahbiard]

I'm also getting this error on Fedora 25 so it's not Mac specific

rustc --print=sysroot
~/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu

[liamdawson]

One silly way you can get this, is to reopen VSCode from a terminal that was opened before you installed rustup, because the PATH won't be updated. Just in case you're trying to debug this issue like I just was. 😞

[KalitaAlexey]

@liamdawson,
It's actually understandable.
It's not an issue because that's how OS works.

[liamdawson]

Agreed, I was just throwing it out there as a troubleshooting check :)

I've just published the new version (0.4.0).
Check whether your issue happens or not.

[robinst]

It still doesn't work for me.

DEBUG: RlsMode: start: no RLS executable

[KalitaAlexey]

@robinst,
How to you start VSCode?
I see you had problems with PATH. This problem is not going to be fixed at the moment.

[robinst]

Via the .app on Mac OS. Ok :/.

[KalitaAlexey]

@robinst,
The problem appears when you run from ".app"? It's more interesting.

I hope it helps.

For anyone else having problems, give this extension a go, it worked better at finding rustup for me:

I have the same issue with recent rustup but only when macOS automatically restores windows on OS startup. I think there must be something missing in env at this point. After restarting VSCode everything works as expected.
