如何在Rust 1.32发行版中安装rustfmt？

Question

I'm on macOS Mojave. I've used Rust in the past and rustfmt has always worked, but I can no longer download rustfmt.

$ rustup show
Default host: x86_64-apple-darwin
stable-x86_64-apple-darwin (default)
rustc 1.32.0 (9fda7c223 2019-01-16)

$ rustup component add rustfmt
error: toolchain 'stable-x86_64-apple-darwin' does not contain component 'rustfmt' for target 'x86_64-apple-darwin'

Is there some other command that I need to execute?

Answer 1

You can try these commands:

rustup toolchain remove stable && rustup toolchain add stable

OR

rustup toolchain remove stable && rustup toolchain install stable

It can help in several cases after compiler version updates, like rustfmt , clippy , or other Rust components.
