matplotlib Python的安装问题

Question

我在安装matplotlib软件包后无法将matplotlib.pyplot作为plt导入.任何建议都将非常感激.

>>> import matplotlib.pyplot as plt
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "//anaconda/lib/python2.7/site-packages/matplotlib-1.3.1-py2.7-macosx-10.5-x86_64.egg/matplotlib/pyplot.py", line 98, in <module>
    _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup()
  File "//anaconda/lib/python2.7/site-packages/matplotlib-1.3.1-py2.7-macosx-10.5-x86_64.egg/matplotlib/backends/__init__.py", line 28, in pylab_setup
    globals(),locals(),[backend_name],0)

    from matplotlib.backends import _macosx
**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.

问题原因 在mac os图像渲染中,matplotlib的结尾(默认情况下使用Cocoa的API渲染的后端是什么).有Qt4Agg和GTKAgg,作为后端不是默认值.设置macosx的后端与其他windows或linux os相比有所不同.

我通过以下方式解决此问题:

• 我假设你已经安装了pip matplotlib,你的root中有一个目录叫做~/.matplotlib.
• 在~/.matplotlib/matplotlibrc那里创建一个文件并添加以下代码:backend: TkAgg
