pm2 no longer launching MM

sdetweil

@JMac which way did u upgrade? manual, git pull, or my script?

I see that you used the manual method, do this

cd ~/MagicMirror
sudo rm -rf node_modules
npm install --omit=dev

JMac

@sdetweil Thanks for your reply, your helping of others has helped me out endlessly with this project.
I run the npm install then get an error ENOTEMPTY around /home/pi/MagicMirror/node_modules/ansi-escapes.
saying the directory isn’t empty.

sdetweil

@JMac and u erased the node_modules folder ( the rm -rf)

JMac

@sdetweil yes ran all three lines you posted.

JMac

@sdetweil Sorry to double reply, I ran the last 2 again and they worked ok, right up until the very end of the npm install when I got an ERR_SOCKET_TIMEOUT.
I’m assuming this is a wifi strength issue as the position of this mirror means it struggles at times.

sdetweil

@JMac yeh, everything is very network dependent…

I ended up installing a mesh wifi system to be able to put an access point near where my hall mirror is

JMac

@sdetweil Managed to run it a second time and everything seems happy, however, the pm2 start mm.sh still isn’t launching the MM itself.
Is there any other way to launch the mirror, or a way to check why it’s suddenly lost function (it was always happy launching and stopping the MM) ?

sdetweil

@JMac so, I would do this

pm2 stop all

cd ~/MagicMirror
npm start

does it run correctly?

you MAY have to update pm2, its just an app too…
depending on how old it was

see the pm2 --help
for the command to do its update

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
