I have upgraded my PyCharm 2018.3 to 2019.1 (professional), which has broken all Jupyter support.
My projects have a run configuration for Jupyter that I would start separately, so I could view and edit my notebooks in Chrome due to the abysmal support in PyCharm itself.
Upgrading to 2019.1 for some reason invalidated those run configurations meaning that I can no longer start Jupyter with the configurations that worked fine before the upgrade.
The newfangled "Managed" Jupyter sever does not start either. After opening a notebook in the PyCharm IDE, PyCharm will try to "auto-launch" the "Managed Jupyter server", and fails with a "Run Error" that is entirely unhelpful in actually telling me what is going wrong:
After this error message, opening the Jupyter URL in Chrome shows a blank page.
On top of that, there does not seem to be a way to just start the Jupyter server without having to open the notebook in PyCharm itself, which is what I don't want to do.
Short of downgrading to 2018.3 again (which is going to happen if there is no easy fix), how do I get Jupyter working again? It was working flawlessly before, and now I'm stuck.
It seems like you haven't done any testing on upgrade scenario's :-(.
