jupyterlab 2.0.0b3 does not start with jupyterhub

[enriqueartal]

I have tried version 2.0.0b2 in several computers. If I launch it directly it does not start, the browser asks for waiting or cleaning workspace; in both cases the page stays with jupyter lab logo, no logs indicate the problem even with the option --label.
In other computer, which uses jupyterhub, it complains about not finding labhubapp module. No problems when using 2.0.0a2 in all those computers. Thanks, Enrique.

Solved in 2.0.0b3

-jupyterlab 2.0.0b3 starts locally but not with jupyterhub. No clue from logs (extension has been updated).

Hi @enriqueartal, we removed labhubapp in 2.0 beta, you can use c.Spawner.default_url = '/lab' in your config. I opened #7844 to make a note of this in the change log.

It works for me now. I replaced c.Spawner.cmd = ['jupyter-labhub'] by c.Spawner.cmd = ['jupyterhub-singleuser'] in the config file.

Thanks!
