I believe this could be solved by adding a post-install script to rebuild electron, as described in this thread
So to sum up: go to the modules/MMM-PIR-Sensor, then npm install electron-rebuild
then npm install

Hi,

Same issue here. I did a reinstall of the module and the instructions above

output of npm install electron-rebuild:

For me a simple

npm install
npm rebuild

Fixed the problem. (not changing anything else, well maybe I also deleted the package-lock.js)
