rust-analyzer is not being automatically proxied after installing

[Cavig01]

Verification

• I searched for recent similar issues at https://github.com/rust-lang/rustup/issues?q=is%3Aissue+is%3Aopen%2Cclosed and found no duplicates.
• I am on the latest version of Rustup according to https://github.com/rust-lang/rustup/tags and am still able to reproduce my issue.

Problem

Just as in the title.
Both belonging to DUP_TOOLS, rustfmt doesn't seem to have the problem. Why?

Steps

$ rustup component add rust-analyzer and
$ rust-analyzer, you'll get:

bash: rust-analyzer: command not found

@Cavig01 It seems that I cannot reproduce this issue on my ARM64 Mac:

Did you do anything special?

@rami3l I've just tried. It appears that it was because I installed rustup by pacman. Rustup installed by rustup-init.sh doesn't have the problem.

@Cavig01 Thanks for the investigation! This could be an interesting issue to be reported to the package maintainers then.

Since there's really not much we can do on our side, I'm closing this issue. Please feel free to contact us if you have other questions!

I've found the cause. In case whoever else meet this problem:
This is an intentional design on the pacman package rustup. It's not that rust-analyzer isn't being proxied, but proxied at /usr/lib/rustup/bin/rust-analyzer. It was to avoid conflict between rust-analyzer installed by rustup and one by pacman, since it is also an available pacman package.

To solve this problem, you can just add /usr/lib/rustup/bin/ in your $PATH variable.
