pip安装报错：is not a supported wheel on this platform
可能的原因1：
安装的不是对应python版本的库，下载的库名中cp27代表python2.7,其它同理。
可能的原因2：
（下载的是对应版本的库，然后仍然提示不支持当前平台）
我下载到的numpy库文件名：
使用pip安装(在命令行中):
报错：*** is not a supported wheel on this platform
方法（32 位系统的）：在shell中输入import pip; print(pip.pep425tags.get_supported()) 可以获取到pip支持的文件名还有版本，我这里如下：
>>import pip; print(pip.pep425tags.get_supported())
[('cp27',
'none', 'win32'), ('py2', 'none', 'win32'), ('cp27', 'none', 'any'),
('cp2', 'none', 'any'), ('cp26', 'none', 'any'), ('cp25', 'none',
'any'), ('cp24', 'none', 'any'), ('cp23', 'none', 'any'), ('cp22',
'none', 'any'), ('cp21', 'none', 'any'), ('cp20', 'none', 'any'),
('py27', 'none', 'any'), ('py2', 'none', 'any'), ('py26', 'none',
'any'), ('py25', 'none', 'any'), ('py24', 'none', 'any'), ('py23',
'none', 'any'), ('py22', 'none', 'any'), ('py21', 'none', 'any'),
('py20', 'none', 'any')]
通过这里可以发现上面下载的文件名格式是不支持的，修改为：numpy-1.10.4+mkl-cp27-none-win32.whl即可成功安装。
import pip
import pip._internal.pep425tags
print(pip._internal.pep425tags.get_supported())
[('cp37', 'cp37m', 'win32'), ('cp37', 'none', 'win32'), ('py3', 'none', 'win32'), ('cp37', 'none', 'any'), ('cp3', 'none', 'any'), ('py37', 'none', 'any'), ('py3', 'none', 'any'), ('py36', 'none', 'any'), ('py35', 'none', 'any'), ('py34', 'none', 'any'), ('py33', 'none', 'any'), ('py32', 'none', 'any'), ('py31', 'none', 'any'), ('py30', 'none', 'any')]
