无法使用pyenv ipython笔记本导入matplotlib

Question

我是红宝石开发人员，并且已经开始为项目学习python。 我安装了pyenv，pyenv virutualenv，ipython，笔记本，matplotlib。 一切正常，除了我叫的那一部分

import matplotlib.pyplot as plot

然后我从笔记本中得到了这个错误：

---------------------------------------------------------------------------

RuntimeError: Python is not installed as a framework. The Mac OS X backend will not be able to function correctly if Python is not installed as a framework. See the Python documentation for more information on installing Python as a framework on Mac OS X. Please either reinstall Python as a framework, or try one of the other backends. If you are Working with Matplotlib in a virtual enviroment see 'Working with Matplotlib in Virtual environments' in the Matplotlib FAQ.

谁能帮我使它正常工作？

ps：我在使用pyenv的python 2.7.1。

Matplotlib希望在OS X上安装Framework，以便操纵GUI元素。 您可以使用这样的命令安装Framework版本，知道您的python版本和您的环境名称：

env PYTHON_CONFIGURE_OPTS="--enable-framework CC=clang" pyenv virtualenv <python_version> <env_name>
