Black Screen After MM Update

[sonicgoose]

I know others have had this issue in the past and I’ve looked at those posts but can’t find a solution. I have two MagicMirror installations on different RPis — one update no problem with:

pm2 stop MagicMirror
cd /MagicMirror
git pull
npm install

The second one just gives me a black screen. The developer inspector won’t even open in the browser. Here is the tail end of the error log:

Any suggestions?

@sonicgoose said in Black Screen After MM Update:

cd /MagicMirror
git pull
npm install

is MagicMirror really in the root? or in user folder ~/MagicMirror

[sonicgoose]

@sdetweil User. Sorry, I was logged in through ssh as the user, so no need to type the ~ before.

Short answer: ~/MagicMirror

Reinstalled MM and modules from scratch. Backup was too old and I had changed too much since it was done. Reinstalling was faster.
