jupyter插件nbextensions后不显示的解决办法

最近用的好好的jupyter插件，换了主题后就不显示了，找了很多原因没有解决我的办法，有说nbextensions没有启动的原因https://blog.csdn.net/mark__tuwen/article/details/106207530，但我试了报出错误：

> jupyter nbextension enable
Please specify an nbextension/package to enable or disable

这时候，再研究一下jupyter：

> jupyter 
usage: jupyter [-h] [--version] [--config-dir] [--data-dir] [--runtime-dir] [--paths] [--json] [--debug] [subcommand]

Jupyter: Interactive Computing

positional arguments:
  subcommand     the subcommand to launch

optional arguments:
  -h, --help     show this help message and exit
  --version      show the versions of core jupyter packages and exit
  --config-dir   show Jupyter config dir
  --data-dir     show Jupyter data dir
  --runtime-dir  show Jupyter runtime dir
  --paths        show all Jupyter paths. Add --json for machine-readable format.
  --json         output paths as machine-readable json
  --debug        output debug information about paths

Available subcommands: bundlerextension contrib execute kernel kernelspec migrate nbconvert nbextension nbextensions_configurator notebook run
serverextension theme troubleshoot trust

Please specify a subcommand or one of the optional arguments.

这时候你会发现子命令里面有nbextensions_configurator 命令，执行：jupyter nbextensions_configurator enable 可解决问题。
