wasix build not working on macos aarch64 after install

[Firaenix]

Hi,

I just installed cargo-wasix with cargo install cargo-wasix but after writing a simple fibonacci application I cant seem to get it building or running with wasix.

❯ cargo wasix run
error: couldn't read +wasix: No such file or directory (os error 2)

error: aborting due to previous error

error: Could not execute rustc

Caused by:
    failed to execute "rustc" "+wasix" "--print" "sysroot"
        status: exit status: 1

This is happening on macOS Ventura 13.5.1 on an M1 Max

I just ran into this as well.

It seems like the cargo wasix self clean command doesn't remove everything, so rustup gets left in an inconsistent state.

Here is what I was seeing:

$ cargo wasix build
error: toolchain 'wasix' is not installed
error: Could not execute rustc

Caused by:
    failed to execute "rustc" "+wasix" "--print" "sysroot"
        status: exit status: 1

$ rustc +wasix --print sysroot
error: toolchain 'wasix' is not installed

But if we check rustup, we'll see the wasix toolchain is still "installed".

$ rustup show

You need to tell rustup to remove the toolchain before cargo wasix will download it again.

$ rustup toolchain remove wasix
info: uninstalling toolchain 'wasix'
info: toolchain 'wasix' uninstalled

$ cargo wasix build
