No Package.json provided to load dependencies

[sdetweil]

node-helper.js references python-shell node module,
but it is not installed.

users need to do this manually

there is an npm security fix which removes modules not referenced in any package.json file,
so this manual install WILL be deleted on the next npm install of any kind...

please do an npm init and add the info and dependency

Hello sdetweil,

Does my problem have to do with your comment ?
I have followed the entire installation procedure, get the credentials properly.
Put the code but data do not refresh. And I have an error in the log

`
Thanks for your answer.

[sdetweil]

they changed how it needs to be initialized

a simple google search on the error yields a code change
instead of

var PythonShell = require('python-shell')
or 
let PythonShell = require('python-shell')

change to

let {PythonShell} = require('python-shell')

not a MM problem, its a module problem

also MMM-Fitbit is depricated, use MMM-Fitbit2

Yes, I saw it. Thank you @sdetweil
