Even a simple node_help.js example does not run.

@emrhssla said in Even a simple node_help.js example does not run.:

also, you need to install the python-shell component…

need a package.json file

{
  "name": "MMM-Testpython",
  "description": "sample",
  "version": "0.0.1",
  "dependencies": {
    "python-shell": "latest"
  }
}

and then run

npm install

in the module folder

the updated node_helper.js is

var NodeHelper = require("node_helper");
var {PythonShell} = require('python-shell');

module.exports = NodeHelper.create({
  start: function() {},
  
  socketNotificationReceived: function(notification, payload) {
    console.log(this.name + " received a socket notification: " + notification + " - Payload: " + payload);
    
  },
})

and produces this message in the terminal window, when the UI component is clicked

MMM-Testpython received a socket notification: TEST - Payload: [object Object]

Is it normal for these errors to occur?
/modules/MMM-Testpython/package.json

omg…

@emrhssla sorry, I had a name of “sample” when I did it. I guess the - is not allowed

[sdetweil]

@emrhssla that log is only from the module file. Not node_helper

@sdetweil

{
  "name": "MMMTestpython",
  "description": "samples",
  "version": "0.0.1",
  "dependencies": {
    "python-shell": "latest"
  }
}

Do I have to change it like this and install it again? npm install

[sdetweil]

@emrhssla I don’t understand… mine worked perfectly

package.json

{
  "name": "MMM-Testpython",
  "description": "sample",
  "keywords": [
    "   none"
  ],
  "version": "0.0.1",
  "dependencies": {
    "python-shell": "latest"
  }
}

Looks like your system doesn’t have python installed.
