PM2 does not start the Magic Mirror
I recently wanted to build a magicmirror.
I installed the Magicmirror software and also automatically pm2.
Everything worked fine. The Magicmirror came up.
Then i rebooted the Raspberry.
From there on pm2 didn’t work anymore.
This was in the log:
::: //Error: ENOENT: no such file or directory, open 'package.json' :::
Does someone know what i have to do?
@dariocas - First, check to see if anything pm2 related still exists on your Pi: type
pm2 status all. If you get a table in reply, then pm2 is there, you just need to configure it.
If you get “command not found” then you’ll need to install pm2 manually:
npm install pm2 -g. Once that finishes, you’ll want to initalize pm2 with
pm2 startup. It will do a mess of things and at the end it will output a command for you to enter. This is important! You need to copy that command from the output and paste it into the command line. That will enable pm2 to start when the Pi reboots.
Give it a go and let us know what you find.
Dario, what was the command that created this error message.
You need to give us a bit more information
@lavolp3 this was in the LOG of pm2:
Error ENOENT no such file or directory, open ‘packages.json’
I think the command was open packages.json
@dariocas So the error message was created on startup of the mirror? And the mirror did not start?
Can you start the mirror without pm2?
cd ~/MagicMirror npm start dev
Can you post the complete log of the process?
Can you post what is inside the file that was created for the pm2 process?
Still not enough information to help, sorry.
@lavolp3 The Mirror does start if i start it manually.
this is the whole error log:
Error: ENOENT: no such file or directory, open 'package.json' at Object.fs.openSync (fs.js:646:18) at Object.fs.readFileSync (fs.js:551:33) at Object.

and this is the log out:

These are the logs of pm2.
The Mirror does not start if i start it from pm2.
thanks for helping!
I have the same problem.
I installed a fresh MM with pm2. The MM started. But after a reboot the MM does not start automatically.
Unfortunately I have no idea.
It would be grateful, if someone could help me.
Thank you in advance
I would suggest to both of you to follow the complete guide setting up pm2 and the autostart again. It doesn’t take long.
Besides that, what does
give you after reboot?
pm2 status is
pi@raspberrypi:~ $ pm2 status │ Name │ id │ mode │ status │ ↺ │ cpu │ memory │ MagicMirror │ 0 │ 2.6.0 │ fork │ online │ 799 │ 0% │ 16.8 MB │ Use `pm2 show ` to get more details about an app
and in pm2 log I get this every two seconds
pi@raspberrypi:~/.pm2 $ tail -f pm2.log 2019-02-15T15:36:47: PM2 log: App [MagicMirror:0] online 2019-02-15T15:36:48: PM2 log: App [MagicMirror:0] exited with code  via signal [SIGINT]
I tried the complete guide with creating an .sh-File and so on. But unfortenately with the same effect.
@klinge can you first do
pm2 stop all
cd ~/MagicMirror npm start dev
Maybe you can see what happens there.
It seems that pm2 is running the magicmirror start script but MagicMirror won’t start
