node_helper.js does not work.

sdetweil

@emrhssla what is the error?

open a terminal window or ssh window

do

npm start dev &

node_helper output will show up in the terminal window

then on the mirror UI, developers window
select the console tab

note that the filenames are CASE sensitive
so you code should be in

mm/modules/MMM-TestPython

emrhssla

@sdetweil
in terminal, output is

pi@raspberrypi:~/Desktop/MagicMirror $ npm start dev &
[1] 1452
pi@raspberrypi:~/Desktop/MagicMirror $

magicmirror@2.7.1 start /home/pi/Desktop/MagicMirror

@emrhssla i cut/pasted your code to create your module, added it to config.js
and it performs as expected…

i get in developers console

hello~hello~hello~hello~hello~hello~hello~hello~hello~hello~    MMM-Testpython.js:62
 Socket recevied : hello                                        MMM-Testpython.js:71

and in terminal window

notification : TEST

config entry

{
  module: "MMM-Testpython",
  disabled: false,
  position: "middle",
  config:{
    
  }
},

sdetweil

after the npm start &

press enter… you should get the prompt back, and can do any command

add this to your node module start function

  start: function() {
    socketTestpython=this;
    console.log(this.name + " node_helper started")    // < ---- add this

should see this in terminal window

MMM-Testpython node_helper started

i do

@emrhssla that console output doesn’t make sense… cause u should have seen this line at least

Module helper loaded: MMM-Testpython

before the

Launching application

show me your config.js

@emrhssla that doesn’t match with the terminal window output…

in terminal window only

there are only two modules referenced…

never mind, two of mine don’t have position and work fine
delete ---------also, all modules require a position

this what I see on my startup in the terminal window, before the node_modules start outputing their text

@emrhssla ok, trying to replicate… moved mine to desktop/MagicMirror and it worked ok,
working on installing that repo

emrhssla

@sdetweil I don’t see what the problem is.

After upgrading the npm and node to the latest version, I installed the Magic Mirror, and I wonder if that’s the problem.

And I did the npm install python3 and I don’t think this is the cause.

sdetweil

@emrhssla will advise once I see it myself

sdetweil

@emrhssla which MM are u working in?

/home/pi/Desktop/Beauty (see its config/config.js
or
/home/pi/Desktop/Beauty/MagicMirror one? (see ITS config/config.js

they are different (u have MagicMirror installed INSIDE a MagicMirror folder)
to fix this, in /home/pi/Desktop/Beauty do

mv MagicMirror ..

now you will have

/home/pi/Desktop/Beauty
and
/home/pi/Desktop/MagicMirror

emrhssla

@sdetweil
I first ran a magic mirror at /home/pi/Desktop/MagicMirror . But after failing, another one was installed. Running /home/pi/Desktop/Beauty/MagicMirror gave the same result.

In conclusion, there are two magic mirrors: /home/pi/Desktop/MagicMirror and /home/pi/Desktop/Beauty/MagicMirror.

I’ll try it tomorrow, but maybe it doesn’t matter.

sdetweil

@emrhssla when the mirror app is running, can u access from another system at http://mirror_ip:mirror_port

emrhssla

@sdetweil said in node_helper.js does not work.:

when the mirror app is running, can u access from another system at http://mirror_ip:mirror_port

I solved it!!
A month ago, /fi/MagicMirror was installed.
/pi/Magicmirror puts the code above, so node_helper.js work well.

But I don’t know why /pi/Desktop/Beauty/Magicmirror isn’t working. Is this because of /pi/Magicmirror?

Thanks to you, I solved it. Thank you all the time.

@emrhssla said in node_helper.js does not work.:

But I don’t know why /pi/Desktop/Beauty/Magicmirror isn’t working. Is this because of /pi/Magicmirror?

because its a mess with all that macOS level binaries installed…

i had to

rm -rf  ~/Desktop/Beauty/node_modules/electron 
cp ~/MagicMirror/node_modules/electron ~/Desktop/Beauty/node_modules

to get the UI to show on the pi…

i tested before by executing Electron to show some page
in a terminal window ON THE PI
do

~/Desktop/Beauty/node_modules/electron/dist/electron http://cnn.com

this should open electron to show some web page

initially I got a frame, with empty insides
