没有nbextensions标签
请问要怎么解决这个问题，已经重新安装jupyter_contrib_nbextensions很多次了
你pip list 一下，看看这个包装了吗，要是安装了的话，你直接打开http://localhost:8888/nbextensions?nbextension=toc2/main这个网页，配置一下就可以了，正常情况下这个插件按钮是正常自己出现的，我目前还没找到配置按钮的方法，但是你登录这个网页配置的话，是可以使用插件的功能的
提供一个 conda 环境下的解决方案：
同样的问题，我换了一个命令：
conda install -c conda-forge jupyter_contrib_nbextensions
然后 conda 就将我的几个包退回了旧一点的版本，然后就OK了，估计是依赖的问题
题主可以参考一下
你应该是在搭配的虚拟环境中安装的这个插件，你到cmd中输入activate base ，然后再输入pip install jupyter_contrib_nbextensions。
再输入jupyter contrib nbextension install --user。再重启jupyter notebook应该就可以了。
我也是这样的情况，我的jupyter是在服务器上运行的，然后在服务器上安装好要安装的包，但是在本地nbextensions标签不显示
或许可以试试运行 jupyter nbextension enable varInspector/main
不行直接登陆试试 http://localhost:8888/nbextensions\
我也出现这样的问题，不过我的是ubuntu16.04，最后在su权限下全部重新安装问题就解决了，不过只能在su下运行，普通用户还是没有扩展包的标签。你可以试试管理员运行。
我也出现了同样问题，仅在管理员模式下才能出现上述标签
重新安装了anaconda，在just me 和all users哪个选项修改为just me后（原来选的all users），问题解决。
只要安装好相应的包，照楼上输入网址，就可以找到，亲测可用，，注意要先启动jupyter notebook
