I am running Jupyter 4.1.0 on a Mac which I downloaded with Anaconda.
I have tried downloading front-end extensions to Jupyter Notebook but cannot get the packages to validate. For example after I downloaded calico-document-tools with:
jupyter nbextension install https://github.com/Calysto/notebook-extensions/archive/master.zip
When I try to validate it, I get the following.
$ 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
What does this error message mean?
