【问题描述】：

我在安装 matplotlib 时遇到问题。我正在使用 Mavericks，它抱怨通过 pip 安装和从源代码安装（按照此处 https://github.com/matplotlib/matplotlib/blob/master/README.osx 的说明）已弃用的 NumPy API：

之后它在没有完成安装的情况下存在。我已经使用brew 安装了libpng 和freetype，并且我也已经通过pip 安装了NumPy 和SciPy：

numpy==1.8.2
scipy==0.14.0

【问题讨论】：

你只发布了警告，我不会担心那个具体的警告。请发布错误
我编辑了问题。
谷歌是你的朋友。你试过this吗？
@flebool 我该如何解决这个问题？
你注意到我给你发了一个链接吗？

【解决方案1】：

好的，感谢flebool，我也解决了这个问题。在文件夹中

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs

我同时拥有MacOSX10.9.sdk 和MacOSX10.8.sdk，但我不知道它们是否应该同时存在。我有小牛队，所以我认为MacOSX10.8.sdk 可能是问题所在。我删除了它，并成功地从源代码安装了matplotlib。
