@sdetweil Calling npm run server immediately after connecting via ssh yields:

npm error code ENOENT
npm error syscall open
npm error path /home/dvg/package.json
npm error errno -2
npm error enoent Could not read package.json: Error: ENOENT: no such file or directory, open '/home/dvg/package.json'
npm error enoent This is related to npm not being able to find a file.
npm error enoent
npm error A complete log of this run can be found in: /home/dvg/.npm/_logs/2024-08-05T16_42_00_562Z-debug-0.log

If I switch to the MagicMirror directory and call it, I get this:

@sdetweil I’m sorry, but I don’t understand. What exactly is mm? (MagicMirror is running.)

What does npm run server do? (I can visit the IP address of the Pi on my phone or laptop on my home network.)

@sdetweil Okay. Next issue is that MagicMirror-out.log is always empty. I recall that I could find lots of information in there the last time I was setting up a MM, but this time it’s always just blank. (The MagicMirror-error.log file is, sadly, useless because it’s just filled with tens of thousands of lines of Error: Cannot find module 'electron'.)

Any idea why MagicMirror-out.log is always empty?

@sdetweil Oh. So just close that Terminal window and ssh into it again, you mean?

@sdetweil said in Fork Mode:

installers/mm.sh &

That doesn’t seem to work:

~/MagicMirror $ installers/mm.sh &
[1] 11788

> magicmirror@2.28.0 start

It is still returning all the reporting to Terminal.

@sdetweil Oh, nice. That’s a good tip. Thanks!

@sdetweil Awesome! That seemed to do the trick. Thanks!

@sdetweil Yes. I think something is wrong with pm2 itself, because (a) calling the standard pm2 start MagicMirror will appear to work, but it does not actually launch the MagicMirror. This is the output it yields:

~/MagicMirror/modules $ pm2 start MagicMirror
[PM2] Applying action restartProcessId on app [MagicMirror](ids: [ 1 ])

And (b) it shows pm2 as stopped which doesn’t make any sense. I thought pm2 was supposed to always be running.

Calling /installers/mm.sh will launch the MagicMirror, but then I am stuck with it reporting everything back to the ssh Terminal window and I can’t so anything else until/unless I ctrl-z it, which is annoying.

Can anyone help me understand why my .pm2/pm2.log file is filled with the below errors?

2024-08-03T18:30:09: PM2 log: App [MagicMirror:1] online

@sdetweil If electron hasn’t been required for years, then why does a fresh install of everything generate tens of thousands of “can’t find electron” lines in MagicMirror-error.log?
