How to install Yii2 from github?

There here is such Yii2 engine api for searching airtickets. I can not understand how to install it and make it work?
I even specifically linux installed for more convenient work on this project. But I can not understand what is wrong..
I installed NPM with nodejs, then installed Composer and then installed WebPack which is needed in the end. Copied the files to the engine, installed composer, then ran it through npm and webpack, but he does not react.. that's what shows

In the root folder of the project make
npm install
npm run build

By the way, install webpack is not necessary, inside the project will still be installed your.
