pm2 no longer launching MM

[JMac]

@sdetweil when I run npm start from the MM folder I get:

magicmirror@2.23.0 start
DISPLAY=“${DISPLAY:=:0}” ./node_modules/.bin/electron js/electron.js

sh: 1: ./node_modules/.bin/electron: not found

[sdetweil]

@JMac ok, do this

what device is this on? pi3?

cd ~/MagicMirror
rm -rf node_modules/electron
npm install electron@22.3.4
npm start

please advise

[JMac]

@sdetweil this is on a 3b+.
when running npm install I’m now back to an error for ENOTEMPTY for node_modules/ansi-escapes.
it says directory not empty.
I think it wants it renamed no_modules/.ansi-escapes-TiTd7xs1

[sdetweil]

@JMac ok, try this

rm -rf node_modules/electron
rm package-lock.json 
npm install electron@22.3.4
npm start

[JMac]

@sdetweil after running the npm install now getting a different ENOTEMPTY for nodes_modules/basic-auth.
Same issue of directory not empty

[sdetweil]

@JMac weird, this makes no sense

[JMac]

@sdetweil I’m away with work until Friday but obviously want to try and get to the bottom of this.
I’ll likely end up moving the mirror to somewhere way closer to the WiFi router.
Will this stay open until the end of the week?

Out of curiosity when launching via pm2 should it (in the little box that pops up in terminal) mention fork?

[sdetweil]

@JMac this will stay open til u close it…

yes, that is the linux term for starting an independent process

[sdetweil]

@JMac I would rename the existing mm folder
and then run install again, use my script
https://github.com/sdetweil/MagicMirror_scripts

to help move the modules and config, I’d use my backup/restore scripts
https://github.com/sdetweil/MagicMirror-backup-restore

backup before rename, restore after reinstall

[JMac]

may sound like a daft question but how do I rename the magicmirror folder? I’ve run your back up (hopefully).

[sdetweil]

@JMac in Linux the rename command is mv

cd ~
mv MagicMirror newname

[JMac]

sorry to sound extremely daft, but what should I be renaming it? Is there a preferred name or one which makes most sense?

[sdetweil]

@JMac any name that works for you, you are just making room for the installer which is hard coded to use MagicMirror, and will abort if that folder is already created

[JMac]

once a new name is picked can it later be changed back to magicmirror just to keep everything standard?

Also, when you say,
mv magicmirror newname, I’m guessing the newname bit is actually what I want to call it, or do I put the new name after?
I’ve got a terrible feeling I’ll have to start the whole thing again which I definitely won’t look forward to.

[sdetweil]

@JMac new name is whatever u want to call it

it looks like there is a mess, and you are reinstalling.

my backup and restore scripts can capture your config and modules and let you out then back onto a new MagicMirror

but, by saving the folder anything not handled can be recovered

[JMac]

made the name change and started the install.
How long should the install take? After installing the helper tools it’s got about half way across the screen on updating packages and hasn’t moved for about 10 minutes, prior to that it was pretty quick. I tried to use the arrow keys on my keyboard to move up the terminal window a little and have ^[[A[ and ^[[C[ in the list, is this an issue?

[sdetweil]

@JMac depends on how much updating is required… there is a little => arrow moving at the bottom

[JMac]

yea that’s the little widget that wasn’t moving all that much for a good while, low and behold not 2 minutes after posting it starting carrying on. I tried to come and delete the pending post but you got in there pretty quick with the reply.

once this has run do I need to run your update code or will this be the most current version of MM?

[sdetweil]

@JMac this is the most current version… we update versions every 3 months…

if you try update and its the same as current, it just exists, after writing a log message to that effect

upgrade is a two step process… I don’t want to mess anything up…

so, running script with no parms, tests, and sees if there are any issues you need to know about… code that you changed that might be overwritten, …

and if you are happy (or resolved all the issues) , then adding the parm

apply

and running again will DO the upgrade

[JMac]

So I run the restore and some things have loaded up fine, so the default calendar and new headlines. everything else hasn’t.
I had an extended calendar module, and a PIR sensor to shut the screen off after 5 minutes.

The were some npm err and npm warn issues.

The PIR sensor was the most useful feature I had but I genuinely don’t think I could replicate how I got it working in the first place. It was a case of loads of misses then an eventual hit (plenty of luck).

DO I need to restart the pi for some of these changes to come into effect, or do I need to start messing with modules again, or do I need to do a further update to some modules? Is this the parm you mentioned?
