rustup-install 命令

常用示例

说明

rustup install downloads and installs one or more Rust toolchains. It is an alias for rustup toolchain install. A toolchain is identified by a channel (stable, beta, nightly), an exact version (1.78.0), and optionally a date (nightly-2025-01-15) and host triple (stable-x86_64-unknown-linux-gnu). If the toolchain is already installed it is updated to the latest release on that channel.

参数

--profile _NAME_

Installation profile: minimal, default, or complete. Controls which components are installed.

-c, --component _NAME_

Add a component to the toolchain (for example `rust-src`, `rust-analyzer`, `llvm-tools`, `miri`). May be repeated.

-t, --target _TRIPLE_

Add a cross-compilation target. May be repeated.

--no-self-update

Do not update rustup itself while installing the toolchain.

--force

Reinstall the toolchain even if it appears up to date; on nightly, install even if some requested components are missing.

--force-non-host

Allow installing a toolchain whose host triple does not match the running machine (introduced in rustup 1.28).

--allow-downgrade

Allow choosing an older nightly if the most recent one is missing required components.

-h, --help

Print help.
