@bobt
did u find a solution for your problem ?

yes, of course. thank you.

yes, of course. thank you
this did install the node_module folder in my module folder

as the heading says, i have a problem starting my module. npm start causes the following error:
npm ERR! missing script: start
here is my package.json file:

{
  "name": "emetalcharts",
  "version": "1.0.0",
  "description": "charting commodity prices",
  "main": "emetalcharts.js",
  "private": "true",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "repository": {
    "type": "git",
    "url": "git+https://github.com/sdetweil/SampleModule.git"
  },
  "author": "",
  "license": "MIT",
  "bugs": {
    "url": "https://github.com/sdetweil/SampleModule/issues"
  },
  "homepage": "https://github.com/sdetweil/SampleModule#readme",
  "dependencies": {
    "chart.js": "^2.5.0",
    "sqlite3": "^4.2.0"
  }
}

the following is recommended on many websites:

  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start" : "node ."
  },

this then causes the following error message :

Module.register("emetalcharts", {
^
ReferenceError: Module is not defined

I’m done. Who can help me ?
could it also be a version conflict?
my versions:

 $ node --version
v10.20.1
$ npm --version
6.14.5
