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，当我跑：

$ 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')()

似乎virtualenv正在抓取System python而不是Homebrew Python 2.7.6，但我无法弄清楚原因。

非常感谢任何帮助！

Answer 1

作为一种解决方法，您可以指定用于virtualenv的Python解释器：

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

Answer 2

我用它来安装它：

$ sudo pip install virtualenv

我在某处读过你可能需要使用sudo强制你的机器。我保证不再使用它了。

麻烦用Homebrew的python 2.7.6在OS X 10.9.1上运行virtualenv
