Question

我目前正在使用这个：@ angular / router @ 3.0.0-alpha.7＆amp;我想将它升级到@ angular / router @ 3.0.0-beta.2。这是我的app.routes.ts

import { provideRouter, RouterConfig } from '@angular/router';
import {SubjectsComponent} from './subjects.component';
import {ProfileDetailsComponent} from './profileDetails.component';
import {AgreementComponent} from './agreement.component';

export const routes: RouterConfig = [
 { path: 'subjects', component: SubjectsComponent },
  { path: 'profile', component: ProfileDetailsComponent },
 { path: 'agreement', component: AgreementComponent }
 ];

  export const appRouterProviders = [
  provideRouter(routes)
 ];

我已经更改了路由器的版本，将rc.3更改为rc.4，仍然得到相同的错误。这是我的package.json：

    "dependencies": {
    "@angular/common": "2.0.0-rc.4",
    "@angular/compiler": "2.0.0-rc.4",
    "@angular/core": "2.0.0-rc.4",
    "@angular/forms": "~0.1.0",
    "@angular/platform-browser": "2.0.0-rc.4",
    "@angular/platform-browser-dynamic": "2.0.0-rc.4",
    "@angular/router": "^3.0.0-beta.2",
    "@angular2-material/button": "^2.0.0-alpha.6",

Answer 1

just go to your package.json and change

--------> "@angular/router": "3.0.0-alpha-7" to "@angular/router": "3.0.0-beta.2",

and then go to terminal and type npm install .

and this will do what you want :)

this is your answer :---

just update your package.json file with the following code

"@angular/common": "2.0.0-rc.4", "@angular/compiler": "2.0.0-rc.4", "@angular/core": "2.0.0-rc.4", "@angular/forms": "0.2.0", "@angular/http": "2.0.0-rc.4", "@angular/platform-browser": "2.0.0-rc.4", "@angular/platform-browser-dynamic": "2.0.0-rc.4", "@angular/router": "3.0.0-beta.1", "@angular/router-deprecated": "2.0.0-rc.2", "@angular/upgrade": "2.0.0-rc.4"

i have tested this and this works fine now :)

Answer 2

确保在package.json中不再使用@angular/router-deprecated 像这样更新你的package.json :)

 "dependencies": {
    "@angular/common": "2.0.0-rc.4",
    "@angular/compiler": "2.0.0-rc.4",
    "@angular/core": "2.0.0-rc.4",
    "@angular/forms": "0.2.0",
    "@angular/http": "2.0.0-rc.4",
    "@angular/platform-browser": "2.0.0-rc.4",
    "@angular/platform-browser-dynamic": "2.0.0-rc.4",
     "@angular/router": "3.0.0-beta.2",
    "es6-shim": "^0.35.0",
    "jquery": "^2.2.4",
    "jquery-ui": "^1.10.5",
    "leaflet": "^0.7.7",
    "moment": "^2.13.0",
    "ng2-bootstrap": "^1.0.17",
    "ng2-slim-loading-bar": "^1.2.3",
    "ng2-toastr": "^0.3.0",
    "reflect-metadata": "0.1.3",
    "rxjs": "5.0.0-beta.6",
    "systemjs": "0.19.26",
    "zone.js": "^0.6.12"
  }

然后在命令提示符/ terminal

中执行npm install

如何在角度2中升级路由器版本？
