Jupyter lab build fail after installing plotly extension - installation

Question

Plotly figures are not rendered/displayed in jupyterlab. I therefore tried to install the extension jupyter labextension install #jupyter-widgets/jupyterlab-manager jupyterlab-plotly. Afterwards I was asked to run the jupyter lab build and this failed. I have no idea where the problem is.
Install info:
I installed a venv with pyenv running python 3.8.5.
jupyter --version
jupyter core : 4.7.1
jupyter-notebook : 6.4.0
qtconsole : not installed
ipython : 7.25.0
ipykernel : 6.0.3
jupyter client : 6.1.12
jupyter lab : 3.0.12
nbconvert : 6.1.0
ipywidgets : 7.6.3
nbformat : 5.1.3
traitlets : 5.0.5
npm --version
7.11.2
node --version
v16.1.0
I am restricted to use WSL1 because of company requirements.
I’ll post below the command outputs for
jupyter labextension list
jupyter lab build
cat /tmp/jupyterlab-debug-5vr2zquq.log
jupyter labextension install #jupyter-widgets/jupyterlab-manager --minimize=False
Any advice would be appreciated. I have no idea how to fix this.
Thanks

Build failed.
Troubleshooting: If the build failed due to an out-of-memory error, you
may be able to fix it by disabling the dev_build and/or minimize options.
If you are building via the jupyter lab build command, you can disable
these options like so:
jupyter lab build --dev-build=False --minimize=False
You can also disable these options for all JupyterLab builds by adding these
lines to a Jupyter config file named jupyter_config.py:
c.LabBuildApp.minimize = False
c.LabBuildApp.dev_build = False
If you don’t already have a jupyter_config.py file, you can create one by
adding a blank file of that name to any of the Jupyter config directories.
The config directories can be listed by running:
jupyter --paths
Explanation:
dev-build: This option controls whether a dev or a more streamlined
production build is used. This option will default to False (i.e., the
production build) for most users. However, if you have any labextensions
installed from local files, this option will instead default to True.
Explicitly setting dev-build to False will ensure that the production
build is used in all circumstances.
minimize: This option controls whether your JS bundle is minified
during the Webpack build, which helps to improve JupyterLab’s overall
performance. However, the minifier plugin used by Webpack is very memory
intensive, so turning it off may help the build finish successfully in
low-memory environments.

Answer 1

You should not need to install the extension from source. JupyterLab 3.0 introduced prebuilt extensions system that allows users to install extensions from pip (and conda) without the need for the build step making all the trouble of troubleshooting failed builds disappear. It seems that you used an old set of instructions for installing plotly, as plotly 5.0+ supports prebuilt extensions for JupyterLab. First uninstall the source extensions that you just installed (non of those are needed):
jupyter labextension uninstall #jupyter-widgets/jupyterlab-manager jupyterlab-plotly plotlywidget
Optional: verify list of extensions with:
jupyter labextension list
Then install a new plotly version with pip or conda:
pip install "plotly>=5" "ipywidgets>=7.6"
# or, if using conda:
# conda install -c conda "plotly>=5"
# conda install "ipywidgets>=7.6"
Both widget and renderer are included, so no need to install plotlywidget separately.
Check list of extensions again:
jupyter labextension list
You should now see lines with:
jupyterlab-plotly v5.1.0 enabled OK
#jupyter-widgets/jupyterlab-manager v3.0.0 enabled OK (python, jupyterlab_widgets)
(the version may be newer in the future of course).
