在Windows10中安装matplotlib for python时出现问题

Question

每次我尝试在Windows10中安装matplotlib包for python时，都会生成以下错误。我在windows提示符下下载了matplotlib-1.5.1-cp35-none-win_amd64.whl文件，下面是它生成的错误：

我在win32上使用python3.5.2（v3.5.2:4def2a2901a5，2016年6月25日，22:01:18）[MSC v.1900 32 bit（Intel）]，但是matplotlib-1.5.1-cp35-none-win_amd64.whl似乎是我所拥有的Python版本唯一可用的matplotlib包
