Mac下查找python的安装位置以及第三方库

因为有时候会写一个工具放在lib下，对于windows是很好找python安装包的地址以及lib 和 site-packages

但是对于mac来说却是不太容易，现提供方法如下：

亲测可用

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

想进入到该路径下可根据找lib方法找这个文件

2.找lib

我们从上一条数据里摘抄出和lib相关的

\'/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\',

可以查一下路径下的文件：（建议拿windows路径下的文件做个对比找到存储位置，比如win下 py下lib下文件有哪些）

方法1：用终端进入到指定路径下，查看文件

方法2：使用访达快捷键：command + Shift + G

　　（1）打开访达　　　　（2）操作快捷键输入路径　　　　（3）前往　　　　（4）查看文件

　　　　　　经过查找，发现此路径下文件与Windows下py自导lib文件一致
