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.

我想在 jupyter notebook 中导入 matplotlib.pyplot 但出现这些错误。我尝试将 matplotlibrc 文件添加为本网站 (Installation Issue with matplotlib Python) 但失败了。

我遇到了同样的问题。最新版本的jupyter 和matplotlib 似乎已解决此问题，并且在jupyter notebook 之前运行以下命令可解决我系统上的错误：

(env)$ pip install --upgrade jupyter matplotlib

这些是我的 virtualenv 中使用 python 2.7.10 的包的版本：

matplotlib==2.0.0
jupyter==1.0.0
jupyter-client==5.0.0
jupyter-console==5.1.0
jupyter-core==4.3.0
ipython==5.2.2
ipython-genutils==0.1.0

对于旧版本，还有其他解决方法： https://stackoverflow.com/a/35107136/2113258, https://stackoverflow.com/a/21789908/2113258

先生运行命令后：

pip install --upgrade jupyter matplotlib

这个错误正在发生

"ERROR: Could not install packages due to an EnvironmentError: [WinError 5] Access is denied: 
'c:\\users\\nadee\\anaconda3\\lib\\site-packages\\matplotlib\\backends\\_backend_agg.cp37-win_amd64.pyd'
 Consider using the `--user` option or check the permissions."

并正确安装
