itchat.auto_login(hotReload=-1)#原文为hotReload=true
itchat.run()

1. 安装python3，setuptools-40.2.0，pip-18.0（按顺序）：cmd中找到setuptools-40.2.0和pip-18.0的安装目录

   C:\Users\Administrator\AppData\Local\Programs\Python\Python35-32>setuptools-40.2.0>python setup.py install
   C:\Users\Administrator\AppData\Local\Programs\Python\Python35-32>pip-18.0>python setup.py install   

   将C:\Users\Administrator\AppData\Local\Programs\Python\Python35-32加入系统变量的path变量 

   C:\Users\Administrator\AppData\Local\Programs\Python\Python35-32>pip itchat install
   C:\Users\Administrator\AppData\Local\Programs\Python\Python35-32>pip list 显示已安装的pip包 

    

2. 将wechat.py文件放到C:\Users\Administrator\AppData\Local\Programs\Python\Python35-32\Lib\site-packages目录下运行，否则报错ImportError: No module named 'itchat'
3. 若报错You can't get access to internet or wechat domain, so exit.则将ssl的版本降级：cmd在path目录下运行

    pip uninstall -y certifi
    pip install certifi==2015.04.28
