有些时候，我们用pip install *** 难免发生意外，可以采用安装whl的方法，不过...
有时候出现如：
whl is not a supported wheel on this platform
PS C:UsersAdministrator> python Python 3.7.0a2 (v3.7.0a2:f7ac4fe, Oct 17 2017, 16:23:57) [MSC v.1900 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import pip >>> import pip; print(pip.pep425tags.get_supported()) [('cp37', 'cp37m', 'win32'), ('cp37', 'none', 'win32'), ('py3', 'none', 'win32'),

把whl文件名字改成以上任意格式就好了...
