Virtualenv.py沒有主要的職責

Question

我在Mac OS 10.8.5上的初始virtualenv設置有問題。

使用PIP安裝後，我有以下錯誤，當我嘗試運行的virtualenv：

ObLaDalocal:~ dbunz$ virtualenv 
Traceback (most recent call last): 
     File "/usr/local/bin/virtualenv", line 8, in <module> 
     load_entry_point('virtualenv==1.11.4', 'console_scripts', 'virtualenv')() 
     File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 318, in load_entry_point 
     return get_distribution(dist).load_entry_point(group, name) 
     File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 2221, in load_entry_point 
     return ep.load() 
     File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 1959, in load 
     raise ImportError("%r has no %r attribute" % (entry,attr)) 
    ImportError: <module 'virtualenv' from '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/py2app/recipes/virtualenv.py'> has no 'main' attribute 

ObLaDalocal:~ dbunz$ echo $PYTHONPATH 
/usr/local/lib/python2.7/site-packages/matplotlib:/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/py2app/recipes/

我有一些事情夷爲平地，但我能得到的virtualenv才能正常運行。

1. 建立了多版模式PIP：（須藤的easy_install -m PIP）
2. 卸載的virtualenv：sudo的PIP卸載的virtualenv
3. 重新安裝的virtualenv須藤PIP安裝的virtualenv

不是特別神奇。
