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, pngerror: 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
