UnsupportedWheel: matplotlib.xxx.whl is not a supported wheel on this platform解决方案

安装画图工具matplotlib时报错：

UnsupportedWheel: matplotlib-2.0.2-cp27-cp27m-win_amd64.whl is not a supported wheel on this platform.

可在pip.log中查看报错日志：

------------------------------------------------------------
C:\Python27\lib\site-packages\pip\__main__.py run on 08/28/17 09:46:01
matplotlib-2.0.2-cp27-cp27m-win_amd64.whl is not a supported wheel on this platform.
Exception information:

raise UnsupportedWheel("%s is not a supported wheel on this platform." % wheel.filename)
UnsupportedWheel: matplotlib-2.0.2-cp27-cp27m-win_amd64.whl is not a supported wheel on this platform.

出现这种情况，需要确认以下几点：

1. python的版本：2.7还是3.5或其他

2. 电脑版本：32位还是64位

3. pip是否过期

确认使用的python版本为2.7，电脑版本为64位后，尝试

python -m pip install --upgrade pip

后，安装matplotlib成功
