Matplotlib/Pylab 安装问题，无法在 _tkagg 中导入？

Question

导入pylab时出现以下错误。

>>> import pylab
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "//anaconda/lib/python2.7/site-packages/matplotlib-1.4.1-py2.7-macosx-10.5-x86_64.egg/pylab.py", line 1, in <module>
    from matplotlib.pylab import *

ImportError: cannot import name _tkagg

我的系统python信息如下： OS- 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。

先决条件

在 MacOS Yosemite

中安装 命令行工具

command line tool- sudo xcode select --install

解决方案

安装 pip，然后安装 mathplotlib、numpy 和 scipy 软件包（如果您没有安装它们）

 Install pip- sudo easy_install pip

安装 GCC 和 homebrew

运行使用您的首选库执行以下命令

 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)
