导入 pylab 时出现以下错误。

我的系统python信息如下：操作系统- Mac OS X Yosemite

我安装了 matplotlib- 1.4.1. 并且还有最新版本的 tk。任何建议将不胜感激？谢谢。

【问题讨论】：

这是stackoverflow.com/questions/29064669/…的后续问题。接下来我会尝试同时更新XQuartz 和matplotlib，看看是否已经解决了这个问题。不幸的是，错误消息没有提供太多信息。
还可以考虑在 Anaconda 支持论坛 groups.google.com/a/continuum.io/forum/#!forum/anaconda 中发布您的问题
如何你是如何安装 mpl 的？这看起来像 c 库从未构建过。

【解决方案1】：

先决条件

在 MacOS Yosemite 上安装命令行工具

command line tool- sudo xcode select --install

解决方案

安装 pip，如果没有安装 mathplotlib、numpy 和 scipy 包，则安装它们

 Install pip- sudo easy_install pip

使用homebrew安装GCC

使用您喜欢的库运行以下命令

 Install matplotlib- sudo pip install -U matplotlib
 Install numpy- sudo pip install -U numpy (can ignore if you already installed) 
 Install scipy- sudo pip install -U scipy (can ignore if you already installed)
