分析原因
nbextensions已经安装成功，但是启动jupyter的时候，提示
"No module named 'jupyter_nbextensions_configurator"
而且notebook的首页也没有nbextensions标签。
网上搜索了很多文章，尝试过很多方法，甚至卸载jupyter重新安装也不行。
于是决定还是从错误日志入手，既然提示没有module，第一行也给了一个路径
/usr/local/Cellar/jupyterlab/2.0.1/libexec/lib/python3.7/site-packages/
反正死马当活马医，在这个路径下再安装jupyter_nbextensions_configurator试试
pip3 install --target=/usr/local/Cellar/jupyterlab/2.0.1/libexec/lib/python3.7/site-packages jupyter_contrib_nbextensions
结果还真解决了，启动的时候没有提示错误，标签也正常显示
以上这篇Jupyter安装nbextensions,启动提示没有nbextensions库就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
