知道如何解决这个问题吗?
Any idea how to solve this issue?
推荐答案
不幸的是，您被 Python 2.7.7 版本引入的回归所困扰:
You have unfortunately been bitten by a regression introduced by the Python 2.7.7 release:
http://bugs.python.org/issue21652
降级到 Python 2.7.6 或更早版本将暂时解决此问题.
Downgrading to Python 2.7.6 or earlier will address this issue for now.
