RuntimeError: npm dependencies failed to install

I created a new environment in anaconda, installed packages and extensions. Not sure what is going on. Some online resources say it’s a yarn issue, but unsure if it is. Any help will be appreciated.

Steps to install virtual env, packages, and extension:

(base) conda create -n env_name python=3.7 pandas numpy -y
(base) conda activate env_name`
(env_name) conda install -c plotly plotly plotly_express -y
(env_name) jupyter labextension uninstall @jupyterlab/plotly-extension

Hi Dustin, Have you ever figured out this error? I have the exact same one trying to configure plotly for jupyterlab and I can’t figure out a way to solve it 🤔 Thanks in advance!

[AlexAndorra]

Not really – I already had a virtual env for the project I was working on, so I didn’t want to migrate all of it just because of Plotly. So I used Bokeh successfully in that same v-env. If you do need Plotly though, I think Dustin’s answer is good: the error was coming from node.js. So, I’m betting creating a new v-env and a new associated jupyter kernel would have solved the issue. Hope this helps!
