Unable to spawn process '"show"' about cargo-msrv HOT 4 CLOSED

I added rustup as a dependency to the Arch Linux package. (commit)

from cargo-msrv.

I found out that my issue was a missing rustup binary 😅. I had installed rust (and cargo, etc.) through the package manager, not through rustup. After switching to rustup for managing rust installations, this works for me.

Great!

Shouldn't the documentation mention this? I don't think it's explicitly mentioned.

Absolutely. I've created #467 to track this.

Thanks for the report.

Based on the error message, I think that either rustup is not installed or available to the environment, or our call to rustup to detect the available toolchains somehow fails.

I don't have an Arch Linux install available myself unfortunately, which makes this a bit harder to reproduce (I don't have issues on Pop OS). Below I've added some questions, to further pinpoint what is causing the issue.

• Do you have rustup installed? If you run rustup show, what output do you get?

• Is this error all the output you get? Or do you also see a progress bar like in https://asciinema.org/a/mFs1cjmjhCDinQNepooGelnYF ?

• What happens when you run with the following arguments: cargo msrv --log-target stdout --log-level debug --output-format void (running this command will disable the standard output, and enable printing debug information to stdout).

• Does this issue also occur with the latest development version (you can install it by running cargo install cargo-msrv --git https://github.com/foresterre/cargo-msrv)?

• To be sure: are you running cargo msrv show or cargo msrv?
