事情由来
今天帮朋友用python写了个小脚本，知道python可以利用pyinstaller打包成exe，直接pip3 install pyinstaller 安装好了pyinstaller，然后pyinstaller -F -w xxx.py，就去上了趟厕所，拿起纸巾。。。本以为应该早就打包好的exe结果等来的是 command not found，WTF!
解决方法
上网查了很久归根结底就是Mac上环境变量的设置问题
- 找到pyinstaller的快捷方式目录
/Library/Frameworks/Python.framework/Versions/3.7/bin - 将目录添加环境变量目录
编辑环境变量文件
sudo vi ~/.bash_profile
添加一行：
export PATH=${PATH}:/Library/Frameworks/Python.framework/Versions/3.7/bin
退出vim，执行以下命令
source .bash_profile
命令行输入pyinstaller出现以下，恭喜你成功了！
