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 nightly-2022-11-04-aarch64-apple-darwin 1.67.0-aarch64-apple-darwin 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. Commented Oct 22, 2023 at 11:31
  • Thanks @LeftyGBalogh, uninstalling and reinstalling the toolchain worked for me as well. Commented Jun 11, 2024 at 16:53

Could you try these commands:

rustup component remove cargo rustup component add cargo

Try this: rustup component add cargo

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