我安装了numpy，当我去安装Matplotlib时，它失败了。不管我用来安装它的方法如何。以下是我收到的错误。Matplotlib无法在Mac OS 10.8.2上使用Python 2.7.3安装

看起来你没有做的libpng。根据您选择的背景，您也可能会发现其他编译问题。如果你想从源代码编译，你应该明白什么是需求并安装它们。我通常会避免从源代码编译，尤其是对于OSX，如果有很多其他选项可用的话。 – tiago 2013-03-26 16:49:33
我建议安装matplotlib自带的[anaconda]（https://store.continuum.io/cshop/anaconda）。 – 2013-03-26 18:10:29
