如何使用工具链为 Linux 上的所有用户安装 rustup 和 cargo？

Question

I am trying to install rustup with clippy, but I am looking way of installing for all users.

I installed rustup in /opt/setup. Whenever I switch users, I get this:

error: no default toolchain configured

If I try to install a toolchain it does not take /opt/setup but /home/user . I specified RUSTUP_HOME and CARGO_HOME in my .bashrc file but still it chooses /home/user . Is there a way to achieve this?

Answer 1

As of Apr 16, 2016 :

It does not support it now

Even in Sept 10, 2017 the issue is still open, so I'd not wait for it, since installing Rust with clippy is straight forward.

As suggested in the comments elsewhere, you can get your package manager to do it on some distributions. sudo zypper install cargo landed what I needed with openSuse LEAP.
