Error executing Jupyter command ‘contrib’: [Errno ‘jupyter-contrib’ not found]解决办法

先把之前的卸载

pip uninstall jupyter_contrib_nbextensions
pip uninstall jupyter_nbextensions_configurator

然后重新安装

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --trusted-host pypi.tuna.tsinghua.edu.cn jupyter_contrib_nbextensions

然后中间多加一个-

jupyter contrib-nbextension install --user
