python - 使用来自 Homebrew 的 python 2.7.6 在 OS X 10.9.1 上运行 virtualenv 时遇到问题

Question

我通过以下指南安装了 Python 2.7.6:http://hackercodex.com/guide/python-development-environment-on-mac-osx/ .但是，当我运行时:

$ virtualenv test

我得到以下输出:

Traceback (most recent call last):
  File "/usr/local/bin/virtualenv", line 9, in <module>
    load_entry_point('virtualenv==1.11', 'console_scripts', 'virtualenv')()

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']

似乎 virtualenv 正在获取 System python 而不是 Homebrew Python 2.7.6，但我不明白为什么。

如有任何帮助，我们将不胜感激!

作为变通方法，您可以指定用于您的 virtualenv 的 Python 解释器:

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