无法在M上的pippinstalled Python中导入pyplot

Question

我pip安装了python和matplotlib，但是当我输入命令“importmatplotlib.pyplot作为plt”，即使在~/.matplotlib目录中创建matplotlibrc文件（它原来不在那里）之后，我仍然得到下面的错误，行为“backend:TKAgg”

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 Working with Matplotlib in a virtual enviroment see 'Working
