peerDependencies installed but still shows warning

Do you want to request a feature or report a bug?
A Bug I guess

What is the current behaviour?

  "devDependencies": {
    "@angular/animations": "^5.0.0",
    "@angular/cli": "1.5.4",
    "@angular/common": "^5.0.0",
    "@angular/compiler": "^5.0.0",
    "@angular/compiler-cli": "^5.0.0",
    "@angular/core": "^5.0.0",
    "@angular/forms": "^5.0.0",
    "@angular/http": "^5.0.0",
    "@angular/language-service": "^5.0.0",
    "@angular/platform-browser": "^5.0.0",
    "@angular/platform-browser-dynamic": "^5.0.0",
    "@angular/router": "^5.0.0",
    "@types/jasmine": "~2.5.53",
    "@types/jasminewd2": "~2.0.2",
    "@types/node": "~6.0.60",
    "bootstrap": "^4.0.0-beta.2",
    "codelyzer": "^4.0.1",
    "commitizen": "^2.9.6",
    "core-js": "^2.4.1",
    "jasmine-core": "~2.6.2",
    "jasmine-spec-reporter": "~4.1.0",
    "karma": "~1.7.0",
    "karma-chrome-launcher": "~2.1.1",
    "karma-cli": "~1.0.1",
    "karma-coverage-istanbul-reporter": "^1.2.1",
    "karma-jasmine": "~1.1.0",
    "karma-jasmine-html-reporter": "^0.2.2",
    "protractor": "~5.1.2",
    "rxjs": "^5.5.2",
    "ts-node": "~3.2.0",
    "tslint": "~5.7.0",
    "typescript": "~2.4.2",
    "zone.js": "^0.8.14"
  }

These are the dependencies I have. Here angular/core, common requires a peer dependency of rxjs.
I have also mentioned that as a dependency but still getting a warning.

warning " > @angular/[email protected]" has unmet peer dependency "rxjs@^5.5.0".
warning " > @angular/[email protected]" has unmet peer dependency "rxjs@^5.5.0".
warning " > @angular/[email protected]" has unmet peer dependency "zone.js@^0.8.4".

But works well while installing with npm

What is the expected behaviour?
I think it should not show the warning when dependencies are installed.

Please mention your node.js, yarn and operating system version.

Nodejs : 8.9.1
OS: Ubuntu 17.10
yarn : 1.3.2

duplicate #4743

There is a known issue where Yarn is failing to look at the top-level dependencies in package.json when checking for peerDeps. There is a fix being worked on...
