pip安装matplotlib

 

在centos6.5 64bit上用pip安装matplotlib时候报错：

 

* The following required packages can not be built:

                        * freetype, png

error: Setup script exited with 1

这是因为pip不能安装操作系统的依赖库导致的，需要用yum手动安装：

 

$ yum -y install freetype-devel libpng-devel

如果不知道这些库需要安装的包名，可以查一下：

 

$ yum search freetype | grep devel

    freetype-devel.i686 : FreeType development libraries and header files

    freetype-devel.x86_64 : FreeType development libraries and header files

$ yum search png | grep devel

    libpng-devel.i686 : Development tools for programs to manipulate PNG image

    libpng-devel.x86_64 : Development tools for programs to manipulate PNG image
