无法在virtualenv中“将matplotlib.pyplot导入为plt”

我正在虚拟环境中使用烧瓶。我可以通过pip安装matplotlib，并且可以import matplotlib在Python会话中进行安装。但是，当我将其导入为

matplotlib.pyplot as plt

我收到以下错误：

>>> import matplotlib.pyplot as plt
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "//anaconda/envs/myenv/lib/python2.7/site-packages/matplotlib/pyplot.py", line 109, in <module>
    _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup()
  File "//anaconda/envs/myenv/lib/python2.7/site-packages/matplotlib/backends/__init__.py", line 32, in pylab_setup
    globals(),locals(),[backend_name],0)
  File "//anaconda/envs/myenv/lib/python2.7/site-packages/matplotlib/backends/backend_macosx.py", line 24, in <module>
    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.

我对为什么它要求我将Python安装为框架感到困惑。它不存在吗？“将Python作为框架安装”是什么意思，如何安装？

回答：

这个解决方案对我有用。如果你已经在虚拟环境中使用pip安装了matplotlib，则只需键入以下内容：

$ cd ~/.matplotlib
$ nano matplotlibrc

然后backend: TkAgg在那写。如果你需要更多信息，请转到解决方案链接。
