Honestly no idea. I have no problem with a fresh installation of the demo app.

$ uname -a

$ python3 --version
Python 3.7.2

$ npm -v
6.11.2

No idea about the “JSON parsing” error, honestly.

BTW I use python version 2, but I’ve also tested with python 3:

server/ $ PYTHON=python3 npm install

You can also try by setting PYTHON env variable to python2.
