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。
