具体如下：

lwk@qwfys:~$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
info: downloading installerWelcome to Rust!This will download and install the official compiler for the Rust
programming language, and its package manager, Cargo.Rustup metadata and toolchains will be installed into the Rustup
home directory, located at:/home/lwk/.rustupThis can be modified with the RUSTUP_HOME environment variable.The Cargo home directory is located at:/home/lwk/.cargoThis can be modified with the CARGO_HOME environment variable.The cargo, rustc, rustup and other commands will be added to
Cargo's bin directory, located at:/home/lwk/.cargo/binThis path will then be added to your PATH environment variable by
modifying the profile files located at:/home/lwk/.profile/home/lwk/.bashrcYou can uninstall at any time with rustup self uninstall and
these changes will be reverted.Current installation options:default host triple: x86_64-unknown-linux-gnudefault toolchain: stable (default)profile: defaultmodify PATH variable: yes1) Proceed with standard installation (default - just press enter)
2) Customize installation
3) Cancel installation

This would reload your PATH environment variable to include
Cargo's bin directory ($HOME/.cargo/bin).To configure your current shell, you need to source
the corresponding env file under $HOME/.cargo.This is usually done by running one of the following (note the leading DOT):
. "$HOME/.cargo/env"            # For sh/bash/zsh/ash/dash/pdksh
source "$HOME/.cargo/env.fish"  # For fish
lwk@qwfys:~$

在当前终端中激活env环境

source "$HOME/.cargo/env"

这个时候就可以正常使用rust相关命令了。
