As per issue https://github.com/SimonBiggs/scriptedforms/issues/59 I am getting the error:

Ahh, bummer. Okay. As a workaround install jupyterlab, then install scriptedforms. I'll need to fix that.

[SimonBiggs]

Instead of focusing on jupyterhub compatibility tonight I'll need to focus on getting Travis CI set up. Having mistakes like this get through isn't really acceptable.

[SimonBiggs]

Alright this is fixed in scriptedforms 0.5.13. Can you run pip install scriptedforms --upgrade

[SimonBiggs]

If this is fixed on your end with 0.5.13 just close down this issue.

[robmarkcole]

Tryin on my windows machine at work:

I've already updated jupyterhub (0.8.1) and lab (0.31.8)

[SimonBiggs]

Can you run pip install scriptedforms --upgrade

[SimonBiggs]

Actually do this:

pip uninstall scriptedforms
pip install scriptedforms --no-cache

[SimonBiggs]

So, I just removed the trouble code. Now if you want scriptedforms to work as a notebook server extension (which is what is needed for jupyterhub) you'll have to do the following:

pip uninstall scriptedforms
pip install scriptedforms --no-cache
jupyter serverextension enable --py scriptedforms

[robmarkcole]

OK scriptedforms installed which is good. I then get:

[SimonBiggs]

Thanks rob, sorry about that. I really messed up this notebook server extension thing. Okay, try scriptedforms 0.5.15

[SimonBiggs]

So:

pip uninstall scriptedforms
pip install scriptedforms --no-cache
jupyter serverextension enable --py scriptedforms

[SimonBiggs]

@robmarkcole any success?

[robmarkcole]

I need to figure out how to run jupyterhub on my work PC first. jupyterhub is not on the PATH, I have the same problem with sourceand venv

[SimonBiggs]

I don't think it's worth trying to install jupyterhub on a windows machine...

[SimonBiggs]

Alright, Travis CI is set up :). I think I'm going to call it a night. I'll dig down into jupyterhub for you tomorrow night hopefully.

[robmarkcole]

OK getting this error on my Mac. Not that the original issue is fixed in 5.15 so we can close and have jupyterhub as separate issue
