Package requires Node version <6.0.0

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

error Error running install script for optional dependency: "/AlpineSkiHouse/src/AlpineSkiHouse.Web/node_modules/optipng-bin: Command failed.

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

Consider specifying the expected/required node version in the readme, or removing the dependency

For clarification, this also causes the gulp "images" task to fail

Thanks! I will take a look at this today.

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
