pm2 do not work after v2.8.0 Update

Klinge

Thank you for your help.

But unfortunately it doesn´t work.

I cleared the logfiles and started the MM as you described. The MM also started. And so I saved the state. But after I restarted the Pi, the MM did not start automatically anymore.

PM2 status was empty

pi@raspberrypi:~ $ pm2 status

@Klinge interesting error reported similar behavior

https://github.com/Unitech/pm2/issues/2006

if node or npm versions change, may need to rerun

pm2 startup

command

Klinge

Thank you for your advice.

What exactly did I do?

I installed npm again with

sudo npm install -g pm2

Then I entered

pm2 startup
pm2 start /home/pi/MagicMirror/installers/mm.sh

Der MM startete. And then

sudo pm2 flush
pm2 flush
pm2 save
sudo pm2 save

And when I restart the PI, MM start automatically.

I do not know exactly what helped. But it works.

Thank you again :-)

@Klinge cool!.. thanks for the feedback

pm2 startup should have told you to execute another command. right?

on my system

odroid@odroid:~/MagicMirror$ pm2 startup
[PM2] Init System found: systemd
[PM2] **To setup the Startup Script, copy/paste the following command:**
sudo env PATH=$PATH:/usr/bin /usr/local/lib/node_modules/pm2/bin/pm2 startup systemd -u odroid --hp  /home/odroid

@Klinge said in pm2 do not work after v2.8.0 Update:

Then I entered

pm2 startup
pm2 start /MagicMirror/installers/mm.sh

This path is wrong.

Klinge

@sdetweil Yes, you are right

on my sytem it was

sudo env PATH=$PATH:/usr/bin /usr/lib/node_modules/pm2/bin/pm2 startup systemd -u pi --hp /home/pi

@bhepler Yes, you are right too.

My path above was relative, not absolute. But of course, it was wrong. I entered the absolute path. So I have improved it above :-)

I do have the same issue and although I managed to make MM start automatically I now have two instances and one restarts every few seconds because of the same error:

How do I:
a) fix MagicMirror startup script
or
b) make it stop from auto starting (e.g. stopping it manually via pm2 stop MagicMirror and then saving the state with pm2 save doesn’t work)

sdetweil

@Ivanov_d pm2 stop 0
Then pm2 remove 0
