pywinauto: 导入时遇到 "TypeError: LoadLibrary() argument 1 must be string, not unicode"

经查询, 看到了同样的问题, 在stackoverflow上面,

pywinauto import error for python 2.7 - Stack Overflow
http://stackoverflow.com/questions/41653306/pywinauto-import-error-for-python-2-7

按照帖子里的回答, 问题出在: python 2.7.13里的ctypes模块有了新的变化. 解决办法是
1. 要么降级到python 2.7.12里
2. 要么升级pywinauto到0.6.1以上.
我选择第二种方案.

upgrade pywinauto to 0.6.2 from 0.5

之后, 导入pywinauto, 成功了!
