安装Matplotlib库报错error C1083的终极解决办法，无法找到ft2build.h

**安装Matplotlib库报错error C1083的终极解决办法：

1，手工下载freetype
2，解压后到目录\freetype-2.10.1.tar\freetype-2.10.1\include\freetype下
3，复制上述目录里的文件至C:\Program Files (x86)\Windows Kits\8.1\Include\winrt下
上述文件大多数都是.h的文件，让我们头疼很久的ft2build.h文件也在该目录下！
然后启动pip install matplotlib

安装应该就没问题里了，我从网上找了很多办法，都试过了，没用。自己摸索的办法。

如果上述办法还是有报错，可根据报错信息里的文件名，在上面提到的freetype下找所需的文件如法炮制即可！

以下是我安装时的部分报错信息，仅供参考：
