Failed to build hello-rust example

When trying to build the hello-rust example (cargo build --release), it fails and prints the following error:

error: the 'cargo' binary, normally provided by the 'cargo' component, is not applicable to the 'nightly-2022-11-03-aarch64-apple-darwin' toolchain

Steps to reproduce

  1. Download ZIP from GitHub
  2. Move hello-rust folder out (I moved it to my projects folder)
  3. Modify Cargo.toml so that dependencies don't specify paths
  4. In the hello-rust directory, run the following commands:
    1. rustup default nightly
    2. rustup target add thumbv7em-none-eabihf
    3. cargo build --release
  5. Build fails

Desktop

  • OS: macOS Ventura 13.2 (a) Beta (22D7750270d)
  • rustup: 1.25.1 (bb60b1e89 2022-07-12)
  • rustc: 1.67.0-nightly (edf018221 2022-11-02)
  • cargo: 1.67.0-nightly (7e484fc1a 2022-10-27)

Potential solution

In the rust-toolchain.toml file, changing channel to "nightly" seems to resolve this issue.

Try uninstalling your toolchain with rustup uninstall nightly-2022-11-03-aarch64-apple-darwin, and installing it again.

Alright, seems like that worked!

Dunno why that happened, but I guess I'll close the issue then.

Thanks @katekyy!

@valentinegb I'm also at a bit of a loss why that might have happened, but glad to hear you got it resolved.
