install failed because of the version of gevent

[shisaq]

I've tried to install it step by step, but always got stuck when using pip install -r requirements.txt.

I found the reason was because of the version of gevent.

After I changed the version to gevent==1.1.b3 in requirements.txt and tried for 1 more time, it worked.

More error info and solution, see this.

Thank you for the awesome demo!
