在centos6.5 64bit上用pip安裝matplotlib時(shí)候報(bào)錯(cuò)：
* The following required packages can not be built:
* freetype, pngerror: Setup script exited with 1
這是因?yàn)閜ip不能安裝操作系統(tǒng)的依賴庫(kù)導(dǎo)致的，需要用yum手動(dòng)安裝：
$ yum -y install freetype-devel libpng-devel
如果不知道這些庫(kù)需要安裝的包名，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
