No that's expected. That will be the first error you see if you're using the unpatched version of JupyterLab. ScriptedForms doesn't yet work with the released version of JupyterLab. This pull request needs to go through for that to work:

https://github.com/jupyterlab/jupyterlab/pull/4334

To get it to work while that pull request is in transit you will need to download my fork of jupyterlab, swap to the "allow-angular-templates" branch, and then follow the jupyterlab contributor documentation on how to install jupyterlab from source.

[SimonBiggs]

Discussion on whether or not my pull request is the right approach needs to be had. The JupyterLab team are quite busy with prepping for a release today or tomorrow. Any pull request of mine will have to wait for the Beta 3 release, if it gets accepted.

[SimonBiggs]

If you're interested in the discussion head on over to https://gitter.im/jupyterlab/jupyterlab

[SimonBiggs]

Oh and yes, I skipped to the last line of the error log. That last line is due to needing the pull request. But the middle one in there is due to your https chain being broken by an "employer-in-the-middle". https://en.m.wikipedia.org/wiki/Man-in-the-middle_attack

To fix that can you create a config file that declares to the JupyterLab package manager that having the man in the middle is okay. The following comment mentions what to put in the file and where to put it.

Do you know if its possible to offline install the allow angular version? I tried but its missing several dependencies. I found the dependencies online but not sure where JupyterLab is looking for them locally (if at all)

Any suggestions?

[olivercrask]

Figured it out but would not recommend... requires so many dependencies

[SimonBiggs]

Maybe play easy mode. Install it on another computer... then chuck it on a USB :)

[olivercrask]

That's the new plan, just waiting on a python install :)

[SimonBiggs]

I might install a dev version of jupyterlab into the portable bundle. It looks like my pull request won't make the release happening in the next couple of days. So it will have to wait until beta 3 before a standard python install will work :(
