NBExtension installs but will not validate

See original GitHub issue

I ran $ jupyter nbextension install and was able to install the extension in /usr/local/share/jupyter/nbextensions.

However, when I attempt to enable the extension, I get:

$ jupyter nbextension enable calico-document-tools
Unrecognized JSON config file version, assuming version 1
Enabling notebook extension calico-document-tools...
      - Validating: problems found:
        - require?  X calico-document-tools

Any idea what this error message means?

I’m having a similar problem. I am able to install and validate the tools, but they do not work in the notebook. On the Jupyter console I’m getting a 404 for the typo.js,

[W 14:45:08.208 NotebookApp] 404 GET /nbextensions/typo/typo.js?v=20160907144355 ( 14.50ms referer=

And in the developer console in the notebook when I enable spell check and type:

accessing `MarkdownCell` is deprecated. Use `require("notebook/js/textcell").MarkdownCell`   main.min.js:21:11
TypeError: document.dictionary is undefined   main.js:47:2

I am also seeing some errors when it is loading:

Error: Script error for "nbextensions/typo/typo"


Also, the spellcheck from works for me.

I’m seeing this too, on one installation. On another everything appears ok. Looking into it…
