在OS X 10.9.1上使用python 2.7.6從Homebrew上運行virtualenv問題

Question

我通過以下指南安裝了Python 2.7.6：http://hackercodex.com/guide/python-development-environment-on-mac-osx/。然而，當我運行：

$ virtualenv test 

我得到以下輸出：

Traceback (most recent call last): 
    File "/usr/local/bin/virtualenv", line 9, in <module> 
    load_entry_point('virtualenv==1.11', 'console_scripts', 'virtualenv')() 
    File "/usr/local/Cellar/python/2.7.6/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/virtualenv.py", line 820, in main

    dst_filename = change_prefix(filename, dst_prefix) 
    File "/usr/local/Cellar/python/2.7.6/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/virtualenv.py", line 1079, in change_prefix 
    (filename, prefixes) 
AssertionError: Filename /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/readline.so does not start with any of these prefixes: ['/usr/local/Cellar/python/2.7.6/Frameworks/Python.framework/Versions/2.7/Extras/lib/python', '/usr/local/Cellar/python/2.7.6/Frameworks/Python.framework/Versions/2.7', '/Users/Charlie/Library/Python/2.7/lib/python/site-packages', '/Users/Charlie/.local/lib/python/2.7/site-packages', '/Users/Charlie/Library/Python/2.7/site-packages', '/Library/Python/2.7/site-packages'] 

好像是virtualenv中抓住蟒蛇系統，而不是自制的Python 2.7.6，但我想不出爲什麼。

任何幫助將不勝感激！

Answer 1

作爲一種變通方法，您可以指定Python解釋器來使用你的virtualenv：

virtualenv test -p /usr/local/bin/python 

Answer 2

我提出用它來安裝它：

$ sudo pip install virtualenv 

我讀的地方，你可能需要通過使用sudo來強制你的機器。我保證不再使用它。
