推荐答案

我找到了解决此问题的方法.只有几天前发布的最新virtualenv(v1.11)才有此问题.从您的site-packages文件夹中删除鸡蛋，然后通过easy_install virtualenv==1.10.1安装以前的版本，virtualenv将正常工作.

I've found a solution to this problem. Only the latest virtualenv (v1.11) which was released just a few days ago has this problem. Remove the egg from your site-packages folder and install the previous version via easy_install virtualenv==1.10.1, virtualenv will work fine.
