Black screen after adding modules.

[sdetweil]

@ljhig u need to upgrade to node v14 for this version of electron. u are on node 10

use nvm to upgrade. have to install nvm first

google search how to do

after node upgrade

run my upgrade script

see https://github.com/sdetweil/MagicMirror_scripts

u will have to use force as the parm instead of apply

[ljhig]

@sdetweil thank you for taking the time to reply, I appreciate it.

I’m new to the forum too btw, so apologies if I’ve posted in the wrong place/generic problem (due to downvotes).

I will follow your instruction as soon as I’m home.

Thanks again :)

@sdetweil said in Black screen after adding modules.:

u will have to use force as the parm instead of apply

again, apologies for my ignorance but how would I do this? node has been updated and ran your update script buy still getting black screen.

[sdetweil]

@ljhig when u did phase 2 of update you were told to use ‘apply’ as parameter

use ‘force’ instead
because my script checks, if u already have the latest, then there is nothing to do.

but I think u have the missing library problem.

if u use pm2 to launch mm, then do
pm2 logs --lines=100

look for ‘module not found’

just in case, to minimize the MM screen do, alt-spacebar, then n
(just like on windows)

[ljhig]

@sdetweil I don’t believe I use PM2, I type:

cd MagicMirror/
npm run start

That works for the original config but not the adjusted one. Should I learn how to install/use pm2 to launch to find out what the missing library problem is?

[sdetweil]

@ljhig don’t need pm2… just scroll the window up where you do npm start

if u want pm2, then use my script to add it… see the end of the list of stuff on my scripts page

[ljhig]

@sdetweil I will eventually use your script once I’ve got this working, I think it’s really useful and will fit my purpose brilliantly. Gift for my sister who is less tech savvy then me!

@ljhig I don’t know. I would start by disabling one module at a time til u find the villian

add

disabled:true,

after the
module:
line
for each module,
restart mm

[ljhig]

@sdetweil cheers, starting from scratch again and adding each module one by one, and running after every minor change. Should allow me to catch a problem before it becomes one.

[ljhig]

@sdetweil I have used your magic mirror auto start script, how do I disable/enable it so I can access the magic mirror?

Now when I type CTRL+Q it automatically reopens after 5-10 seconds.

[sdetweil]

@ljhig pm2’s job is to keep mm running!

minimize, alt-spacebar, n

open terminal window
ctrl-alt-t

pm2 stop all

checkout the other pm2 commands

stop, start, restart, logs, flush

pm2 --help

[ljhig]

@sdetweil thank you! I know I’ve been an absolute pain but just know that I really appreciate experience users offering assistance to simple folk like myself. Have a brilliant day.
