cargo +nightly fails if running without rustup wrapper

[gilescope]

It would be nice if +nightly was a no-op on nightly. (Happy to have a warning saying you're already on nightly, but would like to be able to run the same command line as on stable and have it work.)

Can you say more about what this means? What is the error you are experiencing? What commands did you run? What versions are you using? It shouldn't fail if nightly is already installed.

FWIW, the toolchain selection is done as part of rustup, so this is unlikely to be related to cargo. Rustup has its own tracker at https://github.com/rust-lang/rustup.

If nightly is the default toolchain then cargo +nightly check for example fails because it’s already on nightly.

What is the error that you are getting?

[gilescope]

No subcommand +nightly

Ah. +nighlty on nightly works fine on windows and linux. This seems to only be osx specific hickup.

That indicates that it isn't running the rustup wrapper. I would check that your PATH is configured properly (adding ~/.cargo/bin towards the front). You can also check by running which cargo to check which it is running and make sure it says ~/.cargo/bin/cargo.

Ah didn’t realise that it was part of rustup and not part of cargo. I guess it’s rare enough that we don’t want to give a specialised error message in cargo.

I think it would still be nice to give an special error for this case. Rustup is the official way of installing Rust and a lot of tutorials use it, this could be confusing to newcomers (or in this case confused you)

Especially since this probably isn't the easiest term to google for

Have also hit this a different way this week on a different OS. Nixos doesn’t use rustup and thus any example with +stable or + nightly fails.
