matplotlib无法导入

Question

  

AttributeError: 'module' object has no attribute 'cbook'没有回答我的问题。

import matplotlib.pyplot as plt无效。图像中附有错误。

当我运行pip install matplotlib时，它显示已安装。请参阅下面的日志：

Requirement already satisfied (use --upgrade to upgrade): matplotlib in ./anaconda/lib/python2.7/site-packages Requirement already satisfied (use --upgrade to upgrade): numpy>=1.6 in ./anaconda/lib/python2.7/site-packages (from matplotlib) Requirement already satisfied (use --upgrade to upgrade): python-dateutil in ./anaconda/lib/python2.7/site-packages (from matplotlib) Requirement already satisfied (use --upgrade to upgrade): pytz in ./anaconda/lib/python2.7/site-packages (from matplotlib) Requirement already satisfied (use --upgrade to upgrade): cycler in ./anaconda/lib/python2.7/site-packages (from matplotlib) Requirement already satisfied (use --upgrade to upgrade): pyparsing!=2.0.4,>=1.5.6 in ./anaconda/lib/python2.7/site-packages (from matplotlib) Requirement already satisfied (use --upgrade to upgrade): six>=1.5 in ./anaconda/lib/python2.7/site-packages (from python-dateutil->matplotlib)

更新1 根据评论中的建议，尝试在终端中导入相同的内容。以下是输出

>>> import matplotlib.pyplot as plt
Traceback (most recent call last):

更新2 按照评论中的建议运行更多命令后，我现在收到此错误：

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. 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.
