Jupyter Configurable nbextensions 列表为空

Question

我在我的 venv 中安装了 conda install -c conda-forge jupyter_nbextensions_configurator 和运行 jupyter nbextensions_configurator enable --user，但是 nbextensions 菜单是空的。我已经重启笔记本几次了，没有运气。我怎样才能让菜单显示出来，这样我就可以点击 select TOC 等等？

Answer 1

我在 Github

上的一个未决问题中找到了答案 here

我在 Anaconda 提示符中运行以下内容：

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

（注意提示中conda install -c conda-forge jupyter_nbextensions_configurator已经是运行）

然后启动笔记本，扩展可用：

Answer 2

试试这个：

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

之后你需要安装 conda-forge/label/cf202003 如下：

conda install -c conda-forge/label/cf202003 jupyter_contrib_nbextensions

Answer 3

如果有人还在苦苦挣扎 - 就像我一样 - 使用这个，对我来说效果很好： https://github.com/ipython-contrib/jupyter_contrib_nbextensions/issues/1196#issuecomment-903668248

在 anaconda 导航器中 - 转到环境（在主页下方） - select 基础 - 打开终端

然后粘贴此代码

conda install -c conda-forge jupyter_contrib_nbextensions

然后

jupyter contrib nbextension install --user

之后

conda install -c conda-forge/label/cf202003 jupyter_contrib_nbextensions

然后刷新应用程序 --> 检查 nbextensions
