其他安装信息

Welcome to Rust!

This will download and install the official compiler for the Rust programming language, and its package manager, Cargo.

# cargo, rustc, rustup 和其他工具会被放到～/.cargo/bin目录下
It will add the cargo, rustc, rustup and other commands to Cargo's bin directory, located at:

/Users/micocube/.cargo/bin

# 同时会修改bash的profile文件
This path will then be added to your PATH environment variable by modifying the profile files located at:

/Users/micocube/.profile
/Users/micocube/.bash_profile

You can uninstall at any time with rustup self uninstall and these changes will be reverted.

Current installation options:

 default host triple: x86_64-apple-darwin
   default toolchain: stable
modify PATH variable: yes

创建项目cargo new hello_world --bin这个命令传递了--bin参数因为我们的目标是直接创建一个可执行程序，而不是一个库。

导入到IDE，这里选的是IntelliJ，先安装rust插件，双击shift键，输入plugin

卸载命令：rustup self uninstall,在安装时有提示该命令
