RXJS versions mismatch while installing new dependencies in npm

I've a recurrent problem with [email protected] and [email protected] versions. When I try to install new npm libraries the console shows me this error:

MacBook:angular2-seed$ npm install less
[email protected] /Volumes/Data/Proyectos/Paytime/angular2-seed
├─┬ [email protected] 
│ ├─┬ [email protected] 
│ │ └── [email protected] 
│ ├── [email protected] 
│ ├── [email protected] 
│ ├─┬ [email protected] 
│ │ └── [email protected] 
│ ├─┬ [email protected] 
│ │ └── [email protected] 
│ └── [email protected] 
└── UNMET PEER DEPENDENCY [email protected]

npm WARN @angular/[email protected] requires a peer of [email protected] but none was installed.
npm WARN [email protected] No description
npm WARN [email protected] No repository field.

Then, If I change the version of rxjs I get this other error:

MacBook:angular2-seed$ npm install

> [email protected] postinstall /Volumes/Data/Proyectos/Paytime/angular2-seed
> typings install


└── es6-shim (ambient)

[email protected] /Volumes/Data/Proyectos/Paytime/angular2-seed
└─┬ UNMET PEER DEPENDENCY [email protected]
  └── [email protected] 

npm WARN [email protected] requires a peer of [email protected] but none was installed.
npm WARN [email protected] No description
npm WARN [email protected] No repository field.
npm ERR! code 1
MacBook:angular2-seed$

I'm in a continuous loop and I don't know how to resolve it, could you help me please?

My package.json content is:

Remove "angular2": "2.0.0-beta.17" from your dependencies. That is completely outdated and no longer used.

Angular 2.0.x base dependencies are as follow:

  "dependencies": {
    "@angular/common": "~2.0.2",
    "@angular/compiler": "~2.0.2",
    "@angular/core": "~2.0.2",
    "@angular/forms": "~2.0.2",
    "@angular/http": "~2.0.2",
    "@angular/platform-browser": "~2.0.2",
    "@angular/platform-browser-dynamic": "~2.0.2",
    "@angular/router": "~3.0.2",
    "@angular/upgrade": "~2.0.2",
    "angular-in-memory-web-api": "~0.1.5",
    "bootstrap": "^3.3.7",
    "core-js": "^2.4.1",
    "reflect-metadata": "^0.1.8",
    "rxjs": "5.0.0-beta.12",
    "systemjs": "0.19.39",
    "zone.js": "^0.6.25"
  },

If you are following Angular 2 quickstart example, you can clone it again from the github repo: https://github.com/angular/quickstart
