Package requires Node version <6.0.0

Running yarn using the current Node LTS 6.9.1 yields the following:

This is due to an incompatibility between imagemin and Node versions >6 imagemin/imagemin#216

As a quick fix you can change line 35 of AlpineSkiHouse\src\AlpineSkiHouse.Web\node_modules\download\index.js to

        var target = path.join(dest, path.basename(url.url || url));

I guess we’ll submit a patch to the upstream project.

well, it was tricky what I did :

1. Installed node.js version 4.9.1
2. opened command line, moved to src/AlpineSkiHouse.Web directory
3. executed the next commands

# install packages globally
npm install yarn -g
npm install bower -g
npm install  jspm -g
npm install gulp -g

# following instructions from readme
yarn install
bower install
jspm install # this one may fail with time out but just try again
gulp
