Mac adb配置环境变量后重新打开终端不生效

1.打开终端：

touch .zshrc   
open .zshrc    

2.zshrc文件中加入：

source ~/.bash_profile

3.打开终端执行：

source ~/.zshrc

4.关闭终端再打开输入adb命令进行验证：

adb version

输出结果：
jiabaokang@jiabaokangdembp ~ % adb version
Android Debug Bridge version 1.0.41
Version 30.0.5-6877874
Installed as /Users/jiabaokang/Library/Android/sdk/platform-tools/adb

验证是OK的。
