在OS X上使用virtualenv创建虚拟环境时的问题

Question

我不太确定我的问题是什么。我在尝试配置一个虚拟环境时，遇到了这个错误：

20:59:51 $ virtualenv test -p /usr/local/bin/python

Running virtualenv with interpreter /usr/local/bin/python
New python executable in test/bin/python

OSError: Command /Users/nlang/Code/Python/venvs...ython /Users/nlang/Code/Python/venvs...stall /Library/Python/2.6/site-packa...ar.gz failed with error code 2

我在各种论坛和谷歌上搜索过，但还是没能成功创建一个虚拟环境。我现在卡住了 :(

谢谢

从你提供的输出信息来看，具体情况有点难以判断，但看起来你是在尝试更新一个已经存在的虚拟环境（注意到有Overwriting的提示）。首先，确认一下/usr/local/bin/python这个路径下的Python能正常工作。然后，试着在一个新的（不存在的）文件夹里创建一个虚拟环境（不要用test这个名字）。如果这样还是不行，请更新你的问题，添加这两个操作的输出结果。
