  }

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

@sdetweil oh!!!
thank you very very very much :)

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

console.log(this.name + " received a socket notification: " + notification + " - Payload: " + payload);

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);
  },
})   

omg…

@sdetweil

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

MMM-Testpython

var Testpythons;
Module.register("MMM-Testpython", {

    defaults: {},
    start: function (){
        Testpythons = this;
    },
  
  getDom: function() {
    var element = document.createElement("div")
    element.className = "myContent"
    element.id="divid"
    element.innerHTML = "Hello, World!!! " + this.config.foo
    var subElement = document.createElement("p")
    subElement.innerHTML = "Click" 
    subElement.id = "clickid"
    element.appendChild(subElement)
    return element
  },
  
  notificationReceived: function(notification, payload, sender) {
    switch(notification) {
      case "DOM_OBJECTS_CREATED":
      var elem = document.getElementById("clickid")
      elem.addEventListener("click", () => {
        Testpythons.sendSocketNotification("TEST")
        console.log("hello~hello~hello~hello~hello~hello~hello~hello~hello~hello~")
        elem.innerHTML = "click success"       
      }) 
        break
    }
  },
  
})

node_helper.js

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

module.exports = NodeHelper.create({
  start: function() {},
  
  socketNotificationReceived: function(notification, payload) {
    switch(notification) {
      case "TEST":
        console.log("notification : " + notification)
        this.sendSocketNotification("I_DID")
        break
    }
  },
})  

The notification I_DID in node_helper.js was well communicated and executed. However, the console in node_helper.js is not output…
What is the problem?

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

module.exports = NodeHelper.create({

@sdetweil

            });
        break

  },
})  

console doesnt show Starting module…

I tried to use python-shell. So I successfully finished the npm install python-shell.
But I saw it said that to use python-shell, you must use node_helper.js.
So I tried to execute a simple Python code. The notification I_DID in node_helper.js was well communicated and executed. However, the console in node_helper.js is not output, nor is python-shell working.
What is the problem?

var Testpythons;
Module.register("MMM-Testpython", {

    defaults: {},
    start: function (){
        Testpythons = this;
    },
  
  getDom: function() {
    var element = document.createElement("div")
    element.className = "myContent"
    element.id="divid"
    element.innerHTML = "Hello, World!!! " + this.config.foo
    var subElement = document.createElement("p")
    subElement.innerHTML = "Click" 
    subElement.id = "clickid"
    element.appendChild(subElement)
    return element
  },
  
  notificationReceived: function(notification, payload, sender) {
    switch(notification) {
      case "DOM_OBJECTS_CREATED":
      var elem = document.getElementById("clickid")
      elem.addEventListener("click", () => {
        Testpythons.sendSocketNotification("TESTPYTHON")
        console.log("hello~hello~hello~hello~hello~hello~hello~hello~hello~hello~")
        elem.innerHTML = "click success"
        
      }) 
        break
    }
  },
  socketNotificationReceived: function(notification, payload) {
    switch(notification) {
      case "I_DID":
        console.log("success")
        var elemk = document.getElementById("divid")
        elemk.innerHTML = "I_DID"
        break
    }
  },
})

node_helper.js

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

module.exports = NodeHelper.create({
  start: function() {
    console.log("Starting module: " + this.name);
  },
  
  socketNotificationReceived: function(notification, payload) {
    switch(notification) {
      case "TESTPYTHON":
        console.log("notification : " + notification)
        this.sendSocketNotification("I_DID")
        PythonShell.runString('print("Hello Python")', null, function (err, result) {
            if (err) throw err;
            console.log(result);  
            });
        break
    }
  },
})  

@sdetweil success using notification! thank you!
