如何在Mac上更改Python的系统路径？

Question

我对Pythonpath有问题。

当我打印sys.path的内容时，系统版本出现在Macports版本之前。 如何更改路径，使macports版本永久出现在系统版本之前，我不想在每个程序的开头都反转路径。 如果您有兴趣，这是完整的路径：

['', '/Library/Python/2.7/site-packages/pyglet-1.1.4-py2.7.egg', '/Library/Python/2.7/site-packages/greenlet-0.3.1-py2.7-macosx-10.7-intel.egg', '/Library/Python/2.7/site-packages/cocos2d-0.4.0-py2.7.egg', '/Library/Python/2.7/site-packages/simplejson-2.1.6-py2.7-macosx-10.7-intel.egg', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/PyObjC', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg-info', '/Library/Python/2.7/site-packages']

只需执行以下操作：sys.path.append（“此处的新路径”）
