Hi

I am trying to use the jsdom renderer but I get the following error (latest pyobsplot==0.4.2):

ValueError: Server not started: npm ERR! cb.apply is not a function

Hi,

It seems that the error you get is quite similar to this one ?

Hi @juba , thanks for the fast response. I had also installed npx additionally to pyobsplot, maybe that was the reason. Now I get another error, but maybe it is due to my setup. I have install jupyter on a server and the notebook is created from there.

What version of nodejs and npm are you using? Thanks a lot for your time!

[juba]

If your jupyter installation is on a remote server, is the pyobsplot npm package installed there ?

[joshy]

Ok it was my fault. I had node installed via nvm. However pythons shutil.which("npx") was returning None. For that to fix I added the following to my systemd service file:

Environment="PATH=/home/jarvis/.nvm/versions/node/v20.12.2/bin:$PATH"

The problem is that with systemd the $PATH is not expanded. So probably node executable was not found. I fixed it by changing $PATH to all the paths and now jsdom renderer is working. Thanks for your time and help.

Glad to know it is fixed !
