I am a new user of Julia (v1.5.0) on JupyterLab (v2.2.8). I installed Jupyter via pip (but somehow there also seems to be an installation from conda). Recently I encountered this “WebIO not detected” error when using PlotlyJS, so I followed here and ran
WebIO.install_jupyter_labextension()
It produced this error:
[ Info: Using default Jupyter executable at
'C:\Users\akahs\AppData\Local\Programs\Python\Python38\Scripts\jupyter.exe'; to use a different executable, see the documentation by running?WebIO.install_jupyter_labextension.
An error occured.

Then I tried
WebIO.install_jupyter_labextension(condajl=true)
And it produced another error:

I’m wondering if this has something to do with my pip installation of Jupyter. But a more basic issue is, I’m very confused about pip installation vs. conda installation, which one Julia is using, and even why conda is involved here at all. I wonder if there’s a tutorial/introduction about the relationship between pip/conda.jl/Jupyter/IJulia/etc.?
