I have the exact same issue. Have you found a fix for this?

[lavolp3]

Have you tried reinstalling pm2 or installing the latest version?

sudo npm install pm2@latest -g

I can’t find the line mentioned in the file /usr/lib/node_modules/pm2.
So better reinstall I guess…

@lavolp3 I have not, right now my workaround is not using pm2 at all and just starting Magic Mirror with DISPLAY=:0 npm start

[dawookie1979]

tried re-installing, same issue

[dawookie1979]

@status-board how do I do this

[lavolp3]

@dawookie1979 @Status-Board
can you please explain again how (the command) and from which folder you have installed pm2?
And what is your system running?

[dawookie1979]

i have tried installing pm2 using sudo npm install pm2@latest -g command, either to the root directory or within magic mirror directory.

i am running raspberry pi3 Magic Mirror 2.5

@dawookie1979 - At a guess, it looks like pm2 is not compatible with the version of node that you have on your pi. I would try upgrading node then re-running the pm2 startup command.

[dawookie1979]

thanks, i will try that. Can you give me the command / commands to run this node update.

[Mykle1]

@dawookie1979

sudo apt update

then

sudo apt install nodejs

That should do it.

[dawookie1979]

ok, so the way i fixed this was to totally reinstall magic mirror 2.5. Thank you for your help

Install PM2 using NPM:

sudo npm install -g pm2

Starting PM2 on Boot
To make sure PM2 can do it’s job when (re)booting your operating system, it needs to be started on boot. Luckily, PM2 has a handy helper for this.

pm2 startup

PM2 will now show you a command you need to execute.

Make a MagicMirror start script.
To use PM2 in combination with MagicMirror, we need to make a simple shell script. Preferable, we put this script outside the MagicMirror folder to make sure it won’t give us any issues if we want to upgrade the mirror.

cd ~
nano mm.sh

Add the following lines:

cd ~/MagicMirror
DISPLAY=:0 npm start

Save and close, using the commands CTRL-O and CTRL-X. Now make sure the shell script is executable bij performing the following command:

chmod +x mm.sh

You are now ready to the MagicMirror using this script using PM2.

Starting your MagicMirror with PM2
Simply start your mirror with the following command:

pm2 start mm.sh

You mirror should now boot up and appear on your screen after a few seconds.

Enable restarting of the MagicMirror script.
To make sure the MagicMirror restarts after rebooting, you need to save the current state of all scripts running via PM2. To do this, execute the following command:

pm2 save

And that’s all there is! You MagicMirror should now reboot after start, and restart after any failure.

Controlling you MagicMirror via PM2.
With your MagicMirror running via PM2, you have some handy tools at hand:

Restarting your MagicMirror:

pm2 restart mm

Stopping your MagicMirror:

pm2 stop mm

Show the MagicMirror logs:

pm2 logs mm

Show the MagicMirror process information:

pm2 show mm
