Problem with mmm-openhabfloorplan after fresh install

[maxheartrate]

Hi everyone,

I updated my Magic Mirror and something must have gone wrong. Afterwards, I reinstalled Magic Mirror into a new folder. Everything works fine until I start to load custom modules. My most important one is mmm-openhabfloorplan.

After installation, Magic Mirror won’t start anymore. I get the following message:

> DISPLAY="${DISPLAY:=:0}" ./node_modules/.bin/electron js/electron.js

Does anyone know how to fix this error?

Best, Max

@maxheartrate I found a fix. I had to install the request module manually:

npm install request.

@maxheartrate and here
https://forum.magicmirror.builders/topic/15778/fix-for-black-screen-in-2-16-and-later

more than just request could be not found

@sdetweil Thank you. Everything is working fine now.
