NPM peer Dependencies

I'm at the moment upgrading from Angular 4 to Angular 5 and received some warnings after that, for example:

npm WARN @angular/[email protected] requires a peer of typescript@>=2.4.2 <2.5 but none is installed. You must install peer dependencies yourself.
npm WARN @covalent/[email protected] requires a peer of @angular/common@^4.4.3 but none is installed. You must install peer dependencies yourself.
npm WARN @covalent/[email protected] requires a peer of @angular/core@^4.4.3 but none is installed. You must install peer dependencies yourself.
npm WARN @covalent/[email protected] requires a peer of @angular/forms@^4.4.3 but none is installed. You must install peer dependencies yourself.
npm WARN @covalent/[email protected] requires a peer of @angular/http@^4.4.3 but none is installed. You must install peer dependencies yourself.
npm WARN @covalent/[email protected] requires a peer of @angular/router@^4.4.3 but none is installed. You must install peer dependencies yourself.
npm WARN @covalent/[email protected] requires a peer of @angular/cdk@^2.0.0-beta.12 but none is installed. You must install peer dependencies yourself.
npm WARN @covalent/[email protected] requires a peer of @angular/material@^2.0.0-beta.12 but none is installed. You must install peer dependencies yourself.

This is my package.json

{

    "@types/jasmine": "2.5.38",
    "@types/node": "^6.0.90",
    "codelyzer": "~2.0.0",

    "ts-node": "~2.0.0",
    "tslint": "~4.5.0",
    "typescript": "^2.3.4"
  },
}

My question is now, how do I add those peer dependencies manually and where? I've searched for ways to add them automatically but they do not work.

NOTE:

You don't have to add any peer dependencies, yourself. The message is only displaying that you have unmet dependencies, and I believe you can continue using @covalent package unless something breaks as these are warnings.

This seems to be an issue with the package @covalent as it depends upon @angular4 and it's respective packages and appears to be incompatible . Since there are few breaking changes from angular4 and angular5. So this is an expected behavior. You have two options now precisely:

  1. Submit PR to the said repository, so you can get a fix asap.
  2. Wait for @covalent to release an update for @angular5, and once the update is out, you can safely update both @angular4 itself and @covalent as well.
