5.3.0 does not create a schemas/dask-labextension/plugin.json file on install

[theNewFlesh]

Dask lab extension does not show up in Jupyter Lab settings I have messed with a bunch of config settings and still cannot get this to work.

Environment: docker container running:

• ubuntu 18.04
• python 3.7
• dask 2022.2.0
• dask-gateway 0.9.0
• dask-labextension 5.3.0
  • jupyterhub 3.0.0
  • jupyterlab 3.5.0rc0

and a docker container running:

• ubuntu 22.04
• python 3.10
  • dask 2022.6.1
  • dask-gateway 2022.10.0
  • dask-labextension 5.3.0
  • jupyterhub 3.0.0
  • jupyterlab 3.5.0rc0

• Install method: pip3

Appears that the schema is not valid or something?

Copying plugin.json from pangeo/base-notebook:latest in /srv/conda/envs/notebook/share/jupyter/labextensions/dask-labextension/schemas/dask-labextension to ~/.local/share/jupyter/labextensions/dask-labextension/schemas/dask-labextension fixes the issue.

Not sure why pip3 install dask-labextension doesn't do that in the first place.

[theNewFlesh]

pip3.10 install dask-labextension==5.2.0 creates a plugin.json file in the schema directory. pip3.10 install dask-labextension==5.3.0 does not create a correct plugin.json file in the schema directory.

Thank you for the report @theNewFlesh, I can reproduce your issue. I'm not sure just yet of the cause. Interestingly, the problem doesn't seem to appear for the conda-forge packages, just the ones on pypi. But when I inspect the tarballs, the plugin.json file appears to be there.

[theNewFlesh]

yup

my dockerfile hotfix

RUN echo "\n${CYAN}REPAIR DASK-LABEXTENSION${CLEAR}"; \
    mkdir -p /tmp/dask-labextension && \
    cd /tmp/dask-labextension && \
    wget \
        https://github.com/dask/dask-labextension/archive/refs/tags/5.3.0.tar.gz \
        -O dask-labextension.tar.gz && \
    tar xvf dask-labextension.tar.gz && \
    cp \
        `find . -type f | grep schema/plugin.json` \
        /home/ubuntu/.local/share/jupyter/labextensions/dask-labextension/schemas/dask-labextension/ && \
    rm -rf /tmp/dask-labextension

Node version doesn't seem to affect the issue since I reproduced it with the default version 12 and custom installed version 16 on ubuntu 22.04. A thought..perhaps the schema dir is referenced as "schema" in some places and "schemas" in others?

It happens also on windows pip install, apparently, with dask_labextension-5.3.0-py3-none-any.whl.... a late discovery

[ian-r-rose]

I plan to make another release today to fix this

[ian-r-rose]

I just published a patch release 5.3.1 to PyPI which should fix this. Sorry about the bad wheel, and let me know if you hit any other problems here!
