mac导入matplotlib报错：python is not installed as a framework

版本：python3.6import matplotlib.pyplot as plt报错：**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.
解决方法：1. 当pip安装matplotlib后会存在目录： ~/.matplotlib 2. 在上面的目录下新建一个文件并添加内容 文件：~/.matplotlib/matplotlibrc 文本内容：backend: TkAgg3. 保存后重新执行导入即可解决
