无法“将matplotlib.pyplot导入为plt”在virtualenv [英] Unable to "import matplotlib.pyplot as plt" in virtualenv

问题描述

我正在虚拟环境中使用烧瓶。我能够用pip安装matplotlib，并且可以在Python会话中 import matplotlib 。但是，当我将它导入为

  matplotlib.pyplot为plt 
  

我得到以下错误：

 >>> ; import matplotlib.pyplot as plt 
 
 Traceback（最近一次调用最后一次）：

 RuntimeError：Python没有安装为框架。如果未将Python作为框架安装，则Mac OS X后端将无法正常运行。有关在Mac OS X上将Python作为框架安装的更多信息，请参阅Python文档。请将Python重新安装为框架，或尝试其他后端之一。 
  

我为什么要求我将Python安装为框架感到困惑。它不存在吗？ 将Python作为框架安装意味着什么，以及如何安装它？

解决方案

解决方案为我工作。如果您已经在您的虚拟环境中使用pip安装了matplotlib，则只需输入以下内容： b $ b $ nano matplotlibrc

然后写 backend：TkAgg 在那里。

I am working with flask in a virtual environment. I was able to install matplotlib with pip, and I can import matplotlib in a Python session. However, when I import it as

matplotlib.pyplot as plt

I get the following error:

>>> 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>

    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.

I am confused about why it asks me to install Python as framework. Doesn't it already exists? What does it mean to "install Python as framework", and how do I install it?

解决方案

This solution worked for me. If you already installed matplotlib using pip on your virtual environment, you can just type the following:

$ cd ~/.matplotlib
$ nano matplotlibrc

And then, write backend: TkAgg in there. If you need more information, just go to the solution link.
