在python文件wechat.py里使用这个库的时候，如果遇到如下的错误消息：ModuleNotFoundError: No module named PIL
解决方法是安装pillow这个库：
pip install pillow
如果遇到下面这个超时的错误：
Retrying (Retry(total-1, connect=None, read=None, redirect=None, status-None)) aftery 'ReadTimeoutError("HTTPSConnectionPool(host='pypi.org', port=443): Read timed out./simple/pillow/
可以使用国内镜像代替：
因为wxpy这个库背后其实使用的是微信网页版的功能，所以如果你的python程序在使用wxpy不能正常工作时，先检查你的微信账号是否能够成功登录微信网页版，如果遇到下列这种提示，说明你的微信账号无法使用wxpy库。
