I am unable to compile the apprtc-master server application

I am using a Linux system I am very new to these nmp,node,grunt,appengine,etc... I am trying to compile the apprtc-master application which is provided in a github link https://github.com/webrtc/apprtc

I have this application in Home I also downloaded appengine from https://cloud.google.com/appengine/docs/standard/python/download

I tried to know versions of npm, node.js, grunt as below

krishna@krishna-Latitude-E5400:~/apprtc-master/src/app_engine$ grunt -version
grunt-cli v1.2.0
grunt v0.4.5
krishna@krishna-Latitude-E5400:~/apprtc-master/src/app_engine$ npm -v
3.9.2
krishna@krishna-Latitude-E5400:~/apprtc-master/src/app_engine$ node -v
v6.10.3

And I executed commands for apprtc-master project as below

krishna@krishna-Latitude-E5400:~/apprtc-master$ npm install

npm WARN optional Skipping failed optional dependency /chokidar/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: fsevents@1.1.1
