Jupyterlab 3: Renderer broken inside fresh env with extensions properly installed

[bede]

Thanks for having detailed troubleshooting docs for Jupyterlab issues, however I'm unable to use the plotly_mimetype renderer (blank plot) in a fresh Jupyterlab (3.0.5) conda environment having followed the troubleshooting and getting started guides almost to the letter. The Plotly express plot works if I downgrade to an early 2.x jupyterlab version. This point in particular makes me suspicous that I have encountered an issue, perhaps related to Lab 3.x

Have I somehow missed something? Using Mac OS 10.14.6

Server

1. conda create -n jlab-server jupyterlab nodejs ipywidgets>=7.5
2. jupyter labextension install jupyterlab-plotly@4.14.3
3. jupyter labextension install @jupyter-widgets/jupyterlab-manager plotlywidget@4.14.3
4. jupyter lab build

Kernel
conda install -c plotly plotly=4.14.3

Both jupyter labextension list and the lab UI confirm that these extensions are installed. I'm not confusing server and kernel environments.

$ jupyter labextension list
JupyterLab v3.0.5
/Users/bede/conda/envs/jlab-server/share/jupyter/labextensions
        @jupyter-widgets/jupyterlab-manager v3.0.0 enabled OK (python, jupyterlab_widgets)

Other labextensions (built into JupyterLab)
   app dir: /Users/bede/conda/envs/jlab-server/share/jupyter/lab
        jupyterlab-plotly v4.14.3 enabled OK
        plotlywidget v4.14.3 enabled OK

Re: @nicolaskruchten's suggestion in that thread posted by @ZupoLlask , the console error accompanying this issue is
Uncaught ReferenceError: require is not defined

@bede did you end up finding a solution? I'm in the same boat, but may just downgrade Jupyterlab

[ZupoLlask]

@TheAustinator I found a solution to my problem. Can you please show us the full output of jupyter labextension list?

[bede]

@TheAustinator Alas I did not, and have said goodbye to Plotly for the time being!

@ZupoLlask Can you elaborate?

[TheAustinator]

@ZupoLlask, it started working after I uninstalled all extensions and reinstalled the plotly extension -- I had a bunch of outdated ones, so maybe one of them was interfering. Here's my list now

JupyterLab v3.0.7
/usr/local/share/jupyter/labextensions
        jupyter-matplotlib v0.8.2 enabled OK
        jupyterlab-jupytext v1.3.0 enabled OK (python, jupytext)
        @jupyter-widgets/jupyterlab-manager v3.0.0 enabled OK (python, jupyterlab_widgets)
        @ryantam626/jupyterlab_code_formatter v1.4.3 enabled OK (python, jupyterlab-code-formatter)

Other labextensions (built into JupyterLab)
   app dir: /usr/local/share/jupyter/lab
        jupyterlab-dash v0.4.0 enabled OK
        jupyterlab-plotly v4.14.3 enabled OK

@bede, maybe this will work for you?

@TheAustinator Thanks for sharing a simple and effective solution. Below, I have copied the steps for easy implementation using your comment (applied for my case, Jupyterlab version 3.2.1
RESULTS:
JupyterLab v3.2.1
labextensions
@jupyter-widgets/jupyterlab-manager v3.0.0 enabled ok (python, jupyterlab_widgets)

Other labextensions (built into JupyterLab)
app dir:
jupyter-matplotlib v0.10.2 enabled ok
jupyterlab-dash v0.4.0 enabled ok
jupyterlab-plotly v5.4.0 enabled ok
plotlywidget v4.14.3 enabled ok

ACTIONS TO BE TAKEN
$ jupyter lab clean --all
$ jupyter labextension list
$ jupyter labextension install plotlywidget
$ jupyter labextension install jupyterlab-plotly
$ jupyter labextension install jupyterlab-dash
$ jupyter labextension install jupyter-matplotlib
