Honestly no idea. I have no problem with a fresh installation of the demo app. ```auto $ uname -a Darwin ibc-macbook 18.7.0 Darwin Kernel Version 18.7.0: Thu Jun 20 18:42:21 PDT 2019; root:xnu-4903.270.47~4/RELEASE_X86_64 x86_64 $ 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: ```bash server/ $ PYTHON=python3 npm install ``` You can also try by setting PYTHON env variable to python2. ---
