Mac使用 matplotlib 画图 => RuntimeError: Python is not installed as a framework

Mac使用 matplotlib 画图

遇到问题：

Traceback (most recent call last):  File "/opt/git/scikit-learn-doc-zh/flowchart/src/quickstart/test_matplotlib.py", line 11, in <module>    import matplotlib.pyplot as plt  File "/Users/jiangzl/.virtualenvs/python3/lib/python3.5/site-packages/matplotlib/pyplot.py", line 113, in <module>    _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup()  File "/Users/jiangzl/.virtualenvs/python3/lib/python3.5/site-packages/matplotlib/backends/__init__.py", line 60, in pylab_setup    [backend_name], 0)  File "/Users/jiangzl/.virtualenvs/python3/lib/python3.5/site-packages/matplotlib/backends/backend_macosx.py", line 19, in <module>    from matplotlib.backends import _macosxRuntimeError: 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 using (Ana)Conda please install python.app and replace the use of 'python' with 'pythonw'. See 'Working with Matplotlib on OSX' in the Matplotlib FAQ for more information.

解决方案：

vim ~/.matplotlib/matplotlibrc 

然后输入以下内容： 

backend: TkAgg
