Magic mirror is not showing up

[sdetweil]

@CoopDog1712 yes, sometimes, the install messes up

pm2 stop all
cd ~/MagicMirror
npm install electron@17.2.0

to test

cd ~/MagicMirror
npm start

if all looks good
ctrl-c to stop
then

pm2 start MagicMirror

I should have asked, what pi is this on ? not pi 0 w, right?

[CoopDog1712]

@sdetweil no its a pi 4

[CoopDog1712]

@sdetweil so it works now, and after i enter pm2 start MagicMirror, it loads the software for the magic mirror, the only issue is that their is nothing only a blank screen, no time, weather, nothing. all that comes up is a blank screen. any suggestions?

[sdetweil]

@CoopDog1712 have u added modules?

if so see
https://forum.magicmirror.builders/topic/15778/fix-for-black-screen-in-2-16-and-later

and
pm2 logs --lines=50
will show you what is happening

[CoopDog1712]

@CoopDog1712 no… not in clock module… we ship that

what was the black screen failure message from the console output?

you read the messages and get the name of the missing library, and replace the ??? with that name

the reason YOU have to read the messages is because there are multiple libraries missing…
you only need to fix the ones that impact the modules you installed

[CoopDog1712]

@sdetweil i dont think i saw one. i never installed any modulles, even the ones that should come with it are not showing up

[sdetweil]

@CoopDog1712 ok, still show the messages where u start mm

either via
npm start
or
pm2

if pm2., then
pm2 logs --lines=50

will show the console output

what pi is this?

[CoopDog1712]

@sdetweil pi 4

[CoopDog1712]

@sdetweil

[sdetweil]

@CoopDog1712 ah yes, fun times…

do

pm2 stop all 
cd ~/MagicMirror
npm install electron@17.2.0
npm start 

mm should come up

minimize mm (alt-spacebar, n)

ctrl-c to stop running instance

then

pm2 status

this will show the status or pm2 managed apps.

use the name or the row number

pm2 start xxx

xxx is the name or the row number
for example

pm2 start 0 

[CoopDog1712]

@sdetweil after i installed electron@17.2.0 then started it, this came up

then i did start pm2 start 4, and it started, but was still a blank screen

[sdetweil]

@CoopDog1712 says something is still running…

you didn’t do pm2 stop all

after doing test

ps -ef | grep -i magicmirror

should return nothing

[CoopDog1712]

@sdetweil whoops…
ok is did pm2 stop all and then entered that line of code you gave me and got this

[sdetweil]

@CoopDog1712

ok do

we will delete 1 entry so you don’t have 2 trying to run at the same time
and then reboot

pm2 delete  1
pm2 save
sudo reboot 

[CoopDog1712]

@sdetweil k i rebooted, then i started it up. nothing came up, still a blank screen so i did pm2 stop all and then did pm2 logs --lines=50 and these came up

[sdetweil]

@CoopDog1712

pm2 status again

also, how did you install mm? manual or my automated script?

did you setup MM autostart before adding pm2?

ps -ef | grep -i magicmirror

[CoopDog1712]

@sdetweil i installed it manually, and no it didnt

[sdetweil]

@CoopDog1712 what is the output of pm2 status?
