【Rust】第一节：安装

1 说明

一些学习记录
环境：MacOS

2 步骤

1、执行curl --proto '=https' --tlsv1.2 https://sh.rustup.rs -sSf | sh
2、看到打印

info: downloading installer

Welcome to Rust!

... ...

This path will then be added to your PATH environment variable by
modifying the profile files located at:

  /Users/rogerqian/.profile
  /Users/rogerqian/.bash_profile
  /Users/rogerqian/.zshenv

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

Current installation options:


   default host triple: aarch64-apple-darwin
     default toolchain: stable (default)
               profile: default
  modify PATH variable: yes

1) Proceed with installation (default)
2) Customize installation
3) Cancel installation

3、键入1，回车
4、看到报错

could not amend shell profile: '/Users/rogerqian/.bash_profile': could not write rcfile file: '/Users/rogerqian/.bash_profile': Permission denied (os error 13)`

5、修改权限，执行cd /Users/XXX，然后chmod 777 .profile，如果报错中还有其他文件，同理进行修改
6、查看权限修改是否成功ls -l .profile
7、再次执行步骤1、2、3，看到Rust is installed now. Great!即为成功
8、关闭终端，重新进入，rustc --version，验证是否安装成功
9、下载c编译器xcode-select --install（如果你没有的话）
