Blank screen on start when installing modules

natebrown

Hi,
I just installed MM on my Pi 400 and it was working fine until i tried installing 3rd party modules. When I start it up i get the following code:

> magicmirror@2.17.1 start
> DISPLAY="${DISPLAY:=:0}" ./node_modules/.bin/electron js/electron.js "run"

App threw an error during load
Error: Cannot find module 'logger'

Thank you for your help.

@natebrown I would do another
npm install
in the MagicMirror folder

@natebrown i don’t think it applies here at the moment (unless there was a mistake in the module installation and it overlayed some MM files) delete MagicMirror/node_modules and redo npm install in the MagicMirror folder

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