@sdetweil I got it working reading some other threads :)

Ran these inside the module-folder:

npm install request

npm install valid-url

npm init -y

There seems to be some problem though:

# npm audit report

Im having problem starting my config.js since i added the module MMM-CalendarExt to my Raspberry Pi 3 MM.

(I have installed everything recently so all packages are the latest, it runs fine without MMM-CalendarExt part in the config.)

These are the errors i get.

What can i do to fix this?
