jupyter nbextension install raise error

[wuyanqian0503]

I'm trying to install the extensions with the following set of commands:
jupyter nbextension install my_module [--sys-prefix|--user]
And it raise the following error:

$ jupyter nbextension install . [--sys-prefix|--user]

Traceback (most recent call last):

    sys.exit(notebook.nbextensions.main())

The bit in square brackets describes options, you're not meant to copy the whole thing.

Thanks a lot! Trouble you to fix another error raised when I try to enable the extension.

$ jupyter nbextension install .

Up to date: /usr/local/share/jupyter/nbextensions/.DS_Store
Up to date: /usr/local/share/jupyter/nbextensions/setup.py
Up to date: /usr/local/share/jupyter/nbextensions/my_tarball_bundler/__init__.py

    To initialize this nbextension in the browser every time the notebook (or other app) loads:
    
          jupyter nbextension enable <the entry point>

And to enable the extension:

$ jupyter nbextension enable my_tarball_bundler

Enabling notebook extension my_tarball_bundler...
      - Validating: problems found:
        - require?  X my_tarball_bundler

Seems not able to find the module named 'my_tarball_bundler'

nbextensions are usually javascript files for the frontend. If you're trying to extend the notebook server, you'd normally install it using standard Python packaging (pip etc), and enable it with jupyter serverextension enable.

The examples in the notebook doc is not complete，is there any complete sever extension example that I can refer to ?

[takluyver]

jupyter_nbextensions_configurator is a server extension to allow configuring nbextensions.

Thank you so much! I've installed my server extension and it runs successfully!
