Meshcat does not work when debugging in VSCode

[lucasrm25]

Running Meshcat in debug mode in VSCode:

import meshcat
vis = meshcat.Visualizer()

results the following error:

unknown option --module
usage: /home/q513234/anaconda3/envs/main/bin/python [option] ... [-c cmd | -m mod | file | -] [arg] ...
Try `python -h' for more information.

    raise RuntimeError("the meshcat server process exited prematurely with exit code " + str(server_proc.poll()))
RuntimeError: the meshcat server process exited prematurely with exit code 2

does anyone has an idea, what could be causing this problem?
