Peer dependency issue reflects for angular2-datatable

[zymr-keshav]

Angular v 4.4.6
angular-cli v 1.6.7

angular-database: 1.6.7

BUT whenever I install new package it gives ( in fact reminds ) me for the error of peer dependencies

here is the result of

npm ls

npm ERR! peer dep missing: @angular/common@^2.0.0, required by [email protected]
npm ERR! peer dep missing: @angular/core@^2.0.0, required by [email protected]
npm ERR! peer dep missing: @angular/platform-browser@^2.0.0, required by [email protected]

npm ERR! peer dep missing: @angular/core@^2.0.0, required by [email protected]
npm ERR! peer dep missing: ajv@^5.0.0, required by [email protected]

I also tried adding peerDependencies section in package.json but nothing solved.

HOW to remove all these errors?
