解决方案

这记录为

我相信安装virtualenv 1.10.1会让你继续工作，直到解决这个问题。 b

I'm trying to follow the directions on the Flask installation website but I encountered an error after I used "sudo easy_install virtualenv" to install virtual environment. Not sure

解决方案

This is logged as an issue with the recently released virtualenv 1.11. I had similar issues on Windows with this release.

I believe installing virtualenv 1.10.1 will let you continue working until this issue is addressed.
