jupyter-notebook - Jupyter 可配置的 nbextensions 列表为空

Question

我安装conda install -c conda-forge jupyter_nbextensions_configurator并jupyter nbextensions_configurator enable --user在我的 venv 中运行，但 nbextensions 菜单是空的。我已经重新启动了几次笔记本，没有运气。我怎样才能让菜单显示出来，以便我可以单击并选择 TOC 等？

我在这里找到了答案，在 Github 上的一个公开问题中

我在 Anaconda 提示符下运行了以下命令：

conda install -c conda-forge jupyter_contrib_nbextensions
jupyter nbextensions_configurator enable --user

（注意conda install -c conda-forge jupyter_nbextensions_configurator已经在提示符中运行过）

然后启动笔记本，扩展可用：
