@dazza120 must be in the MagicMirror folder for npm start

[dazza120]

@sdetweil hi im getting the dev window then into console bet there is nothing at all in there just > So what do i have to run in the dev window is it cd MagicMirrior then pm2 start MagicMirrior? im lost just work dam you mirror lol

[sdetweil]

@dazza120 pm2 runs the DEFINITION named x. It doesn’t care about folder.

The setup typically uses the pm2_MagicMirror.json file in installers, or the mm.sh there as well.

mm.sh has a bug, it uses ~ to mark ‘current user’, but when start on boot, the user is root, not pi. So the startup fails. My new installer fixes that.

So, edit mm.sh and change the path to
/home/pi/MagicMirror

[dazza120]

@sdetweil its in that path already but it is completely empty. should it contain text?

[sdetweil]

@dazza120 sorry, what is “it’s”?

[dazza120]

@sdetweil /home/pi/MagicMirror The mm.sh should it contain text?

[sdetweil]

@dazza120 sorry… what is completely empty? mm.sh is in installers folder

[dazza120]

@sdetweil i unhide my files and one is in the location i said with no text and the other is in installer as you said with text

[sdetweil]

@dazza120 remove the one in MagicMirror… useless

Fix the one in installers

[dazza120]

@sdetweil ok done, what to do now. ive just copied the installer one and overwrite the magic mirror path one

[sdetweil]

@dazza120 which one does pm2 want to use? I am not near my computer so can’t get the list of pm2 commands.

pm2 – help

Did u edit the path in mm.sh?

[dazza120]

@sdetweil no i mearly placed it in the magicmirror folder path. its set to Cd /MagicMirror folder already and pm2 -help isnt displaying a list of pm2 commands

[sdetweil]

@dazza120 inside needs to be

cd /home/pi/MagicMirror
DISPLAY=:0 npm start

[dazza120]

@sdetweil changed it what now mate

[sdetweil]

@dazza120 did u try pm2 now?

[dazza120]

@sdetweil pm2 start or the dev thing?

[sdetweil]

@dazza120

Let’s get npm start dev working

[dazza120]

@sdetweil still nothing in the dev console mate, i can start the whole build over again but everytime i go to change the config it doesnt work

[sdetweil]

@dazza120 ok, start again… change the config?

So, you install a module. If it has package.json file you run npm install in the module folder

Then edit config.js and add
Module structure.

{
  module:'somename',
  config: {
  }
},

To the modules array.

If think syntax error, from the MagicMirror folder do,

npm  run config:check
