How can I get the option 'Export Notebook to Html_toc' on the 'Export Notebook as…' menu in Jupyter Lab?

问题

• How can all of the jupyter nbconvert export options be enabled from the Export Notebook As... menu in Jupyter lab?
  • Specifically, how can I get the option to Export Notebook to Html_toc on the menu?
• Following a clean installation of Anaconda, the default export menu is:
• However, as shown in this issue Add nbconvert export options to File --> Export notebook as #7612, there are additional options, which can be run from the console, but do not display in the menu.
• The full menu would look like:

回答1:

• This answer is a roundabout hack for enabling the full menu in Jupyter Lab
• In this situation, I have a clean installation of Anaconda, which includes Jupyter Lab and Jupyter Notebook.
• Upon entering Jupyter Lab, only the minimal Export options are available.

To enable the Html_toc Export option, do the following

1. Go to the Extension Manager in Jupyter Lab and install @jupyterlab/toc
2. Shut down Jupyter lab and go to the Anaconda Prompt
3. Run conda install jupyter_contrib_nbextensions or conda install -c conda-forge jupyter_contrib_nbextensions per Installing jupyter_contrib_nbextensions Guide.
   • This will install a number of extensions to \\Anaconda3\\lib\\site-packages\\jupyter_contrib_nbextensions\\nbextensions\\
   • There are pip install options in the guide, but I haven't tried this for a manual installation of Jupyter Lab and Jupyter Notebook
4. From the Anaconda Prompt, run jupyter notebook
   • During loading of the Jupyter Notebook environment, there where warnings as follows [jupyter_nbextensions_configurator] nbextension '...' has duplicate listings.
   • One location was \\Anaconda3\\..., as mentioned above, and the other was \\Users\\...\\AppData\\\Roaming\\jupyter\\nbextensions\\...
   • This could be because I had a previous installation of Anaconda, but I resolved this issue by renaming \\Users\\...\\AppData\\\Roaming\\jupyter\\nbextensions\\... to \\Users\\...\\AppData\\\Roaming\\jupyter\\nbextensions_old\\...
5. Go to the Nvextensions tab, select the option for Table of Contents (2), and Enable it.
6. Quit / Logout of Jupyter Notebook
7. From the Anaconda prompt, go the jupyter lab
8. Now all of the Export Notebook As... options will be enabled in the file menu.
   • Including, and specifically Export Notebook to Html_toc

Examples

• Here are examples of HTML notebooks with a Table of Contents output from Jupyter Lab. See the DataCamp notebooks.
