[RIKKO14]

Hello,

[sdetweil]

@RIKKO14 how did u update?

is this a pir module needing rebuild?

[RIKKO14]

@sdetweil Quite often I have a logo at the top of my Magic Mirror

and I had for several days on te top of my MM the MMM-Jast to update and MMM-NowPlayingOnSpotify and MMM-DHT-Sensor had not worked. So first I updapte my MM and second uninstall MMM-Jast, MMM-NowPlayingOnSpotify and MMM-DHT-Sensor

cd ~/MagicMirror
rm -rf modules/module_to_delete

and reinstall them
This is where Electron appeared…

[sdetweil]

@RIKKO14 ok,seen this before… MOST times this works

stop MagicMirror

cd ~
rm -rf .config/Electron

note the dot in front of config

restart MagicMirror

@sdetweil
I use PM2,
how to do ?

[sdetweil]

@RIKKO14 pm2 --help will give you the pm2 commands

but

pm2 stop all

[RIKKO14]

@sdetweil
I do this :

but nothing…

[sdetweil]

@RIKKO14 correct… in linux most commands return nothing if successful…

so that is good… you asked to erase a folder
and it did that

now restart MagicMirror

pm2 start MagicMirror

[RIKKO14]

@sdetweil Nothing has changed

[sdetweil]

@RIKKO14 fun… try this

we need to edit a js file

cd ~/MagicMirror/js
nano electron.js

scroll down to

	let address = (config.address === void 0) | (config.address === "") ? (config.address = "localhost") : config.address;

add a bank line after

on the blank line, copy/paste these lines

	mainWindow.webContents.on("new-window", function(event, url) {
      event.preventDefault();
      // This will open a new Electron window to load the url.
      shell.openExternal(url);
  });

so it looks like this when you are done

	let address = (config.address === void 0) | (config.address === "") ? (config.address = "localhost") : config.address;
	mainWindow.webContents.on("new-window", function(event, url) {
      event.preventDefault();
      // This will open a new Electron window to load the url.
      shell.openExternal(url);
  });
	mainWindow.loadURL(`${prefix}${address}:${config.port}`);

ctrl-o to save the file
ctrl-x to exit nano
cd …

then

pm2 restart MagicMirror
