5 years ago Hi @NumesSanguis, the hub_prefix is a property of the SingleUserNotebookApp [1]. You are meant to override it using standard Jupyter config [2]. I'm not sure about the correct value for that property, that question is better asked on the JupyterHub discourse.
[1] https://github.com/jupyterlab/jupyterlab/blob/master/jupyterlab/labhubapp.py#L25 [2] https://jupyter-notebook.readthedocs.io/en/stable/config_overview.html
cf https://github.com/jupyterlab/jupyterlab/issues/6428, where we're absorbing this extension into JupyterLab itself.
Describe the bug After installing jupyterlab-hub, trying to set
page_config.json, removing it, JupyterHub returns a404 : Not Found. Terminal output states ajson.decoder.JSONDecodeError: Expecting ',' delimiter: line 2 column 38 (char 39)--> Realize JSON is wrongly formatted, because comments not allowed just before posting issue --> Still don't know correct path to JupyterHubTo Reproduce Steps to reproduce the behavior: Note:
/opt/miniconda3(system user account) with:conda install -c conda-forge jupyterhubconda install jupyterlab/etc/jupyterhub/Install jupyterlab-hub:
jupyter labextension install @jupyterlab/hub-extensionCreate the
page_config.jsonfile at:/opt/miniconda3/share/jupyter/lab/settings/page_config.jsonInsert
Save and exit
Start JupyterHub:
Find Configuration Panel button in menu and click it
404 Page not found error:
rm /opt/miniconda3/share/jupyter/lab/settings/page_config.jsonJupyterHub lab starts again, but no Configuration Panel menu entree
Create
/opt/miniconda3/share/jupyter/lab/settings/page_config.jsonagain, but withStart JupyterHub again
404 error
Remove
page_config.jsonand it works again.About to submit issue, realize in Preview that JSON is wrongly formatted and
# commentsare not allowed.Still don't know the correct JupyterHub path. Not working:
/etc/etc/jupyterhub/opt/miniconda3/bin/jupyterExpected behavior
page_config.jsonis broken. Instead it breaks the whole JupyterHub.hub_prefixis incorrectly set and jupyterlab-hub won't work.Suggestions
README.mdto give clearer instructions. E.g. how to find your JupyterHub sub-directory.page_config.jsoncreation with the correct path set / support for how to set it, when clicked onHub --> Controlpanelwhen JupyterHub cannot be foundScreenshots If applicable, add screenshots to help explain your problem.
