【问题描述】：

rxjs@5.0.0-beta.12 和 rxjs@5.0.0-beta.6 版本经常出现问题。当我尝试安装新的 npm 库时，控制台会显示此错误：

MacBook:angular2-seed$ npm install less
angular2-quickstart@1.0.0 /Volumes/Data/Proyectos/Paytime/angular2-seed
├─┬ less@2.7.1 
│ ├─┬ errno@0.1.4

└── UNMET PEER DEPENDENCY rxjs@5.0.0-beta.6

npm WARN angular2-quickstart@1.0.0 No description
npm WARN angular2-quickstart@1.0.0 No repository field.

然后，如果我更改 rxjs 的版本，我会收到另一个错误：

MacBook:angular2-seed$ npm install

> angular2-quickstart@1.0.0 postinstall /Volumes/Data/Proyectos/Paytime/angular2-seed
> typings install


└── es6-shim (ambient)

angular2-quickstart@1.0.0 /Volumes/Data/Proyectos/Paytime/angular2-seed
└─┬ UNMET PEER DEPENDENCY rxjs@5.0.0-beta.12

npm WARN angular2-quickstart@1.0.0 No description
npm WARN angular2-quickstart@1.0.0 No repository field.
npm ERR! code 1
MacBook:angular2-seed$

我一直在循环，我不知道如何解决它，请你帮帮我吗？

【解决方案1】：

从您的 dependencies 中删除 "angular2": "2.0.0-beta.17"。那是完全过时的，不再使用了。

Angular 2.0.x 基础依赖如下：

  "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"
  },
