3.2 Alternative: Using System Package Managers (Linux)
Many Linux distributions offer Rust packages through their native package managers. While this can be a quick way to install a version of Rust, it often lags behind the official releases and might not install the complete toolchain managed by rustup. If you choose this route, be aware that you might get an older version and potentially miss tools like cargo or face difficulties managing multiple Rust versions.
Examples using system package managers include:
- Debian/Ubuntu:
sudo apt install rustc cargo(Verify package names; they might differ). - Fedora:
sudo dnf install rust cargo - Arch Linux:
sudo pacman -S rust(Typically provides recent versions). See Arch Wiki: Rust. - Gentoo Linux: Consult Gentoo Wiki: Rust and use
emerge -av dev-lang/rust.
Note: Even if you initially install Rust via a package manager, you can still install rustup later to manage your toolchain more effectively, which is generally the preferred approach in the Rust community.
