Cannot find `cargo` binary on Rust toolchain on Apple M1

Question

I got this error when I override the rustup toolchain to use the rust-toolchain in the repo directory:

error: the 'cargo' binary, normally provided by the 'cargo' component, is not applicable to the '1.69.0-aarch64-apple-darwin' toolchain

The content of my rustup show:

❯ rustup show
Default host: aarch64-apple-darwin
rustup home:  /Users/myhome/.rustup

installed toolchains
--------------------

stable-aarch64-apple-darwin (default)
stable-x86_64-unknown-linux-gnu

1.67.0-x86_64-unknown-linux-gnu
1.67.1-aarch64-apple-darwin
1.68.0-aarch64-apple-darwin
1.69.0-aarch64-apple-darwin

active toolchain

1.69.0-aarch64-apple-darwin (overridden by '/Users/myhome/myrepo/rust-toolchain')
rustc 1.69.0 (84c898d65 2023-04-16)

The rust-toolchain file:

1.69.0

Does anyone know what happens?

Has this been sorted in the meantime? I've just had a somewhat similar toolchain corruption and what sorted it for me was a rustup toolchain uninstall stable and then a rustup toolchain install stable. Let me know if this is still ongoing. – Yoo

Thanks @LeftyGBalogh, uninstalling and reinstalling the toolchain worked for me as well. – Aubree

Answer 1

Could you try these commands:

rustup component remove cargo
rustup component add cargo

Answer 2

Try this: rustup component add cargo

That is odd if cargo was not installed by rustup initially... is that a bug? – Stumper
