如何在Mac上更改我的Python系統路徑？

Question

我有一個關於Pythonpath的問題。

當我打印sys.path的內容時，系統版本出現在Macports版本之前。我如何更改路徑，使macports版本永久出現在系統版本之前，我不想在每個程序的開始處反轉路徑。如果你有興趣，這是整個路徑：

['', '/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']

只是這樣做：sys.path.append（「新路徑這裏」）
