mac os 下 Python 库的路径问题

➜  ~ which pip
/usr/local/bin/pip
➜  ~ which python
/usr/local/bin/python

➜  ~ pip --version
pip 9.0.1 from /Library/Python/2.7/site-packages (python 2.7)
➜  ~ python
Python 2.7.13 (default, Dec 18 2016, 07:03:39)
[GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.42.1)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.path
['', '/usr/local/Cellar/python/2.7.13/Frameworks/Python.framework/Versions/2.7/lib/python27.zip', '/usr/local/Cellar/python/2.7.13/Frameworks/Python.framework/Versions/2.7/lib/python2.7', '/usr/local/Cellar/python/2.7.13/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin', '/usr/local/Cellar/python/2.7.13/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac', '/usr/local/Cellar/python/2.7.13/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages', '/usr/local/Cellar/python/2.7.13/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk', '/usr/local/Cellar/python/2.7.13/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old', '/usr/local/Cellar/python/2.7.13/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/site-packages', '/usr/local/Cellar/protobuf/3.2.0_1/libexec/lib/python2.7/site-packages']

导入sys库，输出sys.path后发现不太对，感觉是 Python 环境不对导致的。小弟刚用 mac ox 不太会用，求问这个问题怎么解决。

Python

usr

local

lib

可能是你的 pip 是 mac 自带 Python 的，而不是后来你用 brew 装 Python 的吧

@kinghui
```
⋊> ~ python -m pip --version 11:10:37
pip 9.0.1 from /usr/local/lib/python2.7/site-packages (python 2.7)
⋊> ~ pip --version 11:10:49
pip 9.0.1 from /Library/Python/2.7/site-packages (python 2.7)
```

是这个问题..

你用的啥解释器？一般解释器都是可以修改 python 环境的，我用的 pycharm 就是可以直接切换环境的

我现在基本只用 virtualenv 了，用的时候 source，不用了直接 rm。

@ziyo12580 我用 IDE 没问题，就是习惯性开个 shell 打开 Python 测试一些东西的时候用不了很尴尬

@yakumo17 我写项目的时候用虚拟环境，但是平时随手跑个什么都习惯用全局环境
