在ubuntu上用pip install grequest安装后，使用的时候发现总是gevent.py报ImportError: No module named zope.interface的错误
File "/usr/local/lib/python2.7/dist-packages/gevent/monkey.py", line 192, in ignores from gevent.events import DoNotPatch File "/usr/local/lib/python2.7/dist-packages/gevent/events.py", line 67, in <module> from zope.interface import Interface ImportError: No module named interface
因为pip安装grequest时也会会安装gevent，zope.interface等，查了原因发现pip安装的路径下，没有此interface，但系统路径下有，所以可以软连接过去
cd /usr/local/lib/python2.7/dist-packages/zope
ln -s /usr/lib/python2.7/dist-packages/zope/interface/
ubuntu使用gevent报ImportError: No module named zope.interface解决
