MMM DHT-Sensor Help

[STEFF92]

Hi, i’m a totally beginner and the temperature/ humidity sensor is one of my first modules i want to install by myself. Here is the github link:

https://github.com/bernardpletikosa/MMM-DHT-Sensor

This were the first things i did:

pi@raspberrypi:~ $ cd ~/MagicMirror/modules
pi@raspberrypi:~/MagicMirror/modules $ git clone https://github.com/bernardpletikosa/MMM-DHT-Sensor.git
Klone nach 'MMM-DHT-Sensor'...
remote: Counting objects: 18, done.
remote: Total 18 (delta 0), reused 0 (delta 0), pack-reused 18
Entpacke Objekte: 100% (18/18), Fertig.
Prüfe Konnektivität... Fertig.
pi@raspberrypi:~/MagicMirror/modules $ cd MMM-DHT-Sensor
pi@raspberrypi:~/MagicMirror/modules/MMM-DHT-Sensor $ npm install

But then there came these lines:

npm WARN prefer global node-gyp@3.6.0 should be installed with -g

> rpi-dht-sensor@0.1.1 install /home/pi/MagicMirror/modules/MMM-DHT-Sensor/node_modules/rpi-dht-sensor
