无法使用 pyenv ipython notebook 导入 matplotlib

Question

我是一名 ruby 开发人员，我已经开始为一个项目学习 python。我安装了pyenv、pyenv virutualenv、ipython、notebook、matplotlib。除了我调用的部分

以外，一切正常

import matplotlib.pyplot as plot

然后我从笔记本上得到这个错误：

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

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.

任何人都可以帮助我让它工作吗？

ps：我在 python 2.7.1 上使用 pyenv。

Answer 1

Matplotlib 需要在 OS X 上安装框架，以便操作 GUI 元素。您可以使用这样的命令安装框架版本，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>
