@sdetweil I just ran npm install in fonts and vendors and now it works. Thank you!

@sdetweil Sorry, should’ve added that. I’m on Windows 10 and used the install guide.

I’ve tried reinstalling Magic Mirror twice after an upgrade gone wrong and when I run the sample config or my custom (previously working) config I get a black screen that says “undefined” everywhere any help is appreciated!

@sdetweil That worked, thank you!

@sdetweil I forgot to mention, I also ran npm install in fonts and vendors and changed package.json to remove the display again

@sdetweil Thank you for replying,
I followed your instructions and ran:

cd ~/MagicMirror
git checkout develop
git pull
npm install

but I still get

npm ERR! code EJSONPARSE
npm ERR! path C:\Users\CompName\MagicMirror/package.json
npm ERR! JSON.parse Unexpected token "." (0x2E) in JSON at position 181 while parsing near "...ts\": {\r\n\t\t\"start\":  ./node_modules/.bin/..."

I was running an old version of Magic Mirror on a Windows 10 build and I decided to update my version.
After updating, I got an error because my package.json still referenced display so I changed it to:

"main": "js/electron.js",
	"scripts": {
		"start": ./node_modules/.bin/electron js/electron.js",
		"start:dev": ./node_modules/.bin/electron js/electron.js dev",

When I run npm start, I get this:

PS C:\Users\CompName\MagicMirror> npm start
npm ERR! code EJSONPARSE
npm ERR! path C:\Users\CompName\MagicMirror/package.json
npm ERR! JSON.parse Unexpected token "." (0x2E) in JSON at position 172 while parsing near "...pts\": {\r\n\t\t\"start\": ./node_modules/.bin/..."

Any help is greatly appreciated!
