 PS: 终端类型根据执行命令`echo $SHELL`显示的结果：
 
-- `/bin/bash` => `bash` => `.bash_profile`
 - `/bin/zsh` => `zsh` => `.zprofile`

 **如果遇到环境变量无效问题，建议回过头来查看终端类型，再做正确的设置。**
 
 从`macOS Catalina`(10.15.x) 版开始，`Mac`使用`zsh`作为默认`Shell`，使用`.zprofile`，所以对应命令：
 
 ```shell
-echo export PATH=/opt/homebrew/bin:$PATH >> ~/.zprofile
-source ~/.zprofile
+echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile
+eval "$(/opt/homebrew/bin/brew shellenv)"
 ```
 
 如果是`macOS Mojave` 及更低版本，并且没有自己配置过`zsh`，使用`.bash_profile`：
 
 ```shell
-echo export PATH=/opt/homebrew/bin:$PATH >> ~/.bash_profile
-source ~/.bash_profile
+echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.bash_profile
+eval "$(/opt/homebrew/bin/brew shellenv)"
 ```
