更改PIP源
使用豆瓣源：
pip -i https://pypi.douban.com/simple XXXX

安装virtrualenv和virtualenvwrapper-win基本使用
1.创建Python3的虚拟环境
virtualenv VIRTUALENV_NAME –python=PYTHON_PATH
example: virtualenv TEST –python=D:\Python35\python.exe
创建Python2的环境同样。
2.激活虚拟环境
Windows下：
VIRTUALENV_NAME_PATH\Scripts\activate
D:\PycharmProjects\TEST\Scripts\activate
退出虚拟环境:
VIRTUALENV_NAME_PATH\Scripts\deactivate.bat
D:\PycharmProjects\TEST\Scripts\deactivate.bat
py -2 -m pip install virtualenvwrapper-win
mkvirtualenv –python=D:\Python35\python.exe articles35
退出虚拟环境：
deactivate
no module win32api错误
pip install pypiwin32
