因為有時候會寫一個工具放在lib下，對於windows是很好找python安裝包的地址以及lib 和 site-packages
但是對於mac來說卻是不太容易，現提供方法如下：
親測可用
1.首先找site-packages
import sys print(sys.path)
/usr/local/bin/python3.7 /Users/tuyoo/Documents/pytext/test02/other_file/a_011.py ['/Users/tuyoo/Documents/pytext/test02/other_file', '/Users/tuyoo/Documents/pytext/test02', '/usr/local/Cellar/python/3.7.0/Frameworks/Python.framework/Versions/3.7/lib/python37.zip', '/usr/local/Cellar/python/3.7.0/Frameworks/Python.framework/Versions/3.7/lib/python3.7', '/usr/local/Cellar/python/3.7.0/Frameworks/Python.framework/Versions/3.7/lib/python3.7/lib-dynload', '/usr/local/lib/python3.7/site-packages']
/usr/local/bin/python3.7 /Users/tuyoo/Documents/pytext/test02/other_file/a_011.py ['/Users/tuyoo/Documents/pytext/test02/other_file', '/Users/tuyoo/Documents/pytext/test02', '/usr/local/Cellar/python/3.7.0/Frameworks/Python.framework/Versions/3.7/lib/python37.zip', '/usr/local/Cellar/python/3.7.0/Frameworks/Python.framework/Versions/3.7/lib/python3.7', '/usr/local/Cellar/python/3.7.0/Frameworks/Python.framework/Versions/3.7/lib/python3.7/lib-dynload', '/usr/local/lib/python3.7/site-packages'] #site-packages 所在
想進入到該路徑下可根據找lib方法找這個文件
2.找lib
我們從上一條數據里摘抄出和lib相關的
'/usr/local/Cellar/python/3.7.0/Frameworks/Python.framework/Versions/3.7/lib/python37.zip', '/usr/local/Cellar/python/3.7.0/Frameworks/Python.framework/Versions/3.7/lib/python3.7', ' /usr/local/Cellar/python/3.7.0/Frameworks/Python.framework/Versions/3.7/lib/python3.7/lib-dynload',
可以查一下路徑下的文件：（建議拿windows路徑下的文件做個對比找到存儲位置，比如win下 py下lib下文件有哪些）
方法1：用終端進入到指定路徑下，查看文件
方法2：使用訪達 快捷鍵：command + Shift + G
（1）打開訪達 （2）操作快捷鍵輸入路徑 （3）前往 （4）查看文件
經過查找，發現此路徑下文件與Windows下py自導lib文件一致
備注：把寫好的工具拽到lib下，放在lib以后可以通過：import 模塊”導入不報錯 就是成功
