ng serve in demo folder gives this crypto error.

Cloned the repo. Did npm run demo.

OS: Mac OS X El Capitan
Node Version: v6.10.0
npm -v: 4.4.4

Also any possibility of a setting up a live demo, so we can take a quick look if this is the right component someone wants to use. It took me almost 1/2 hour to get npm install to complete and then this...

Seems to be a webpack issue - then again not, its an angular material issue. read my next comment.

Changing the version of angular material to "@angular/material": "2.0.0-beta.5" in the package.json file instead of "@angular/material": "^2.0.0-beta.5" worked. Apparently angular material now needs @ angular/cdk and this is not present in the pacakage.json file, and therefore broke everything in the material world.

npm update (once you have changed the package.json as mentioned above)
then run
ng serve - works.

Can you please confirm that ng2-page-scroll has no dependency with angular-material as such?

Sorry for the late follow up.
ng2-page-scrolldoes not have a dependency on angular/material, but the demo application, which is included in the git repo, does. However, the demo app is not shipped via npm.
An update of angular/material added the peer-dependency requirement for angular/cdk, which caused the demo app and build process of this project to fail, as the angular/material constraint automatically pulled the latest version.
