任何建议为何会引发此错误?

Any suggestions why this error is being thrown?

10.6上的virtualenv也存在一个错误，请参见

There's also a bug with virtualenv on 10.6 See the ticket on virtualenv's bitbucket. Even if you solve the problem you're having you'll still run into another problem (I think image not found for Python.framework, but I don't remember - I didn't take any notes when I ran into this)

我对此进行了一些调查，希望通过python 2.7解决问题的根源-确实人们对此有所了解，并向CPython提交了补丁以对其进行修复.

I did some investigating into this and I hope the root of the problem with be resolved with Python 2.7 - certainly people know about it, and submitted a patch to CPython to fix it.

但是，似乎有些人在10.6.2和virtualenv 1.4.5 ...上还是取得了不错的成绩，或者不再使用系统Python(macports，手动构建).

However, it does seem like some people have had good results with 10.6.2 and virtualenv 1.4.5... or not using the system Python anymore (macports, build-by-hand).
