-However, in contrast to `component add clippy` or `component add rustfmt`, this does not actually place a `rust-analyzer` binary in `~/.cargo/bin`, see https://github.com/rust-lang/rustup/issues/2411[this issue]. You can find the path to the binary using:
-[source,bash]

-$ rustup which --toolchain stable rust-analyzer
