angular - 在 npm 中安装新依赖项时 RXJS 版本不匹配

Question

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，控制台向我显示此错误:

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 
│ │ └── prr@0.0.0 
│ ├── image-size@0.5.0 
│ ├── mime@1.3.4 
│ ├─┬ mkdirp@0.5.1 
│ │ └── minimist@0.0.8 
│ ├─┬ promise@7.1.1 
│ │ └── asap@2.0.5 
│ └── source-map@0.5.6 
└── UNMET PEER DEPENDENCY rxjs@5.0.0-beta.6

npm WARN @angular/core@2.0.1 requires a peer of rxjs@5.0.0-beta.12 but none was installed.
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，我会得到另一个错误:

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$ 

我在一个连续的循环中，我不知道如何解决它，你能帮我吗？

我的 package.json 内容是:

    "start": "concurrent \"npm run tsc:w\" \"npm run lite\" ",

从您的依赖项中删除"angular2": "2.0.0-beta.17"。那已经完全过时了，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"
  },
