Question

我试图将此目录添加到我的python2.7路径

/usr/local/lib/python2.7/site-packages

我可以使用：

sys.path.append('/usr/local/lib/python2.7/site-packages')

或者我也可以将此行添加到我的〜/ .profile或〜/ .bashrc

export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH

但是，这会将同一目录添加到我的python2.6路径

import sys
from pprint import pprint as pp
pp(sys.path)
['',
 '/usr/local/lib/python2.7/site-packages',
 '/Users/Leo/Desktop/ReactiveFlows/Homework/HW1/HW1/Cantera',
 '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python26.zip',
 '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6',
 '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/plat-darwin',

 '/Library/Python/2.6/site-packages',
 '/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/PyObjC']

有很多方法可以做到这一点，如Modifying Python’s Search Path中所述。

一种方法是将local.pth文件添加到/Library/Python/2.7/site-packages（或已在Python2.7的sys.path中列出的任何目录），其中包含该行

/usr/local/lib/python2.7/site-packages

如何修改单个版本的PYTHONPATH？
