Hi,
I have just updated updated my MagicMirror installation to the current 2.2.0 but now I only get a blank screen.npm start
shows the following output.

Maybe no internet connection? If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues Launching application. ^CShutting down server...
I don’t really know what that version mismatch means. I haven’t changed anything else to my set-up but just updated from the previous release to the current one. Any help before I wipe everything and start all over new?

I had this and managed to correct it by following the steps listed here at the end of the readme. Worked for me but not sure if it’ll work for you so i’d recommend backing up first.
https://github.com/ryck/MMM-DHT-Sensor
cd MMM-DHT-Sensor npm install electron-rebuild ./node_modules/.bin/electron-rebuild
But substituting MMM-DHT-Sensor for your module above ‘MMM-PIR-Sensor’

Thanks for the very quick reply. I am currently backing up my MM install and give it a try.
Edit: For a test I just did a
npm install
and checked if the mirror starts up. Which it did. Thanks so much for your help!

npm install worked for me as well, somehow npm rebuild didnt do this job.
