PM2 does not start the Magic Mirror

DarioCas

Hi!

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?

Regards

@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

DarioCas

@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:

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

pm2 status

give you after reboot?

Klinge

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 [1] 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

and then

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
