I have created automatic installer for RaspberryPi and Linux Debian machines.
Auto install script will propose to install needed dependencies with compatible gcc version.
For OSX machines, auto install script is not yet implented.
So, manuel installation is nedeed and no help will be given for this
cd ~/MagicMirror/modules git clone https://github.com/bugsounet/MMM-Detector cd MMM-Detector npm install
npmcommands (e.g. npm audit fix) are needed after installation (they can break package dependencies)!
