Using mermaid with python

[datamusee]

Hello,
Js2Py seems to be promising.
Mermaid (https://mermaid.js.org/) is installed in my node environment
I'm trying to use mermaid from python, starting with
import js2py
context = js2py.require('mermaid')

I get the following error:
AssertionError: Could not link required node_modules

I suppose there are limitations on js modules, but it's not clear for me. Could you clarify?
