Install script should put rust path in ~/.zprofile on macOS

[JonasEngstrom]

Verification

• I searched for recent similar issues at https://github.com/rust-lang/rustup/issues?q=is%3Aissue 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

Running the installation script from the rust-lang.org install page on macOS adds . "$HOME/.cargo/env" to ~/.profile rather than ~/.zprofile where it needs to be to work.

Steps

1. Run curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
2. Restart Terminal, without manually sourcing the ~/.profile file.
3. Rust will not run until ~/.profile is manually sourced or . "$HOME/.cargo/env" is moved to ~/.zprofile.

Possible Solution(s)

Have the setup script add . "$HOME/.cargo/env" to ~/.zprofile instead of ~/.profile on macOS specifically.

@JonasEngstrom Thanks for reporting.

Support for zprofile has been removed 6 years ago by the then-rustup team, I don't think it's needed any more: #2387

Instead for zsh we are editing .zshenv directly:

rustup/src/cli/self_update/shell.rs

Lines 200 to 205 in dfc31fe

	fn rcfiles(&self, process: &Process) -> Vec<PathBuf> {
	[Zsh::zdotdir(process).ok(), process.home_dir()]
	.iter()
	.filter_map(|dir| dir.as_ref().map(|p| p.join(".zshenv")))
	.collect()
	}

What issue have you encountered in particular with the environment setup?

@rami3l Thank you for your prompt reply!

I was not aware that .zprofile had previously been supported, as I am rather new to Rust. (Hence the recent install.)

The issue I am having is that I need to manually source .zshenv or run the command . "$HOME/.cargo/env" every time I open a new terminal. Adding the line to .zprofile solved the problem for me. I was also able to remove the .zshenv file entirely, as it contained nothing except the command mentioned above.

I would not be surprised if it is an issue with my particular setup, but as far as I can remember I have not reconfigured Z shell apart from adding a few directories to the PATH etc and I am thus running it with pretty much a default configuration. That is why I assumed it was an issue with the install script.

The shells I use are either in the macOS Terminal app or from within VS Code.

@JonasEngstrom I don't use zsh myself but as per ohmyzsh/ohmyzsh#4928 this file should have been loaded.

Would you mind digging into your configuration a bit, say adding an "echo" to .zshenv and see if something happens, and/or remove your path configuration to see if it has changed anything etc.?
