Question

我正在尝试为ionic 4应用程序创建选项卡页面布局。完成配置和设置后，出现错误错误：无法匹配任何路由。网址段：“标签”

首先，当我使用标签模板创建默认启动器时，它不起作用。标签栏显示，但不显示标签内容。经过几天的研究和测试，还没有运气。看看我目前有什么；

  <!-- Tab Buttons -->
  <ion-tab-bar slot="bottom">

    <ion-tab-button tab="tab1" href="/tabs/(tab1:tab1)">
      <ion-icon name="navigate"></ion-icon>
      <ion-label>tab1</ion-label>
    </ion-tab-button>

    <ion-tab-button tab="tab2" href="/tabs/(tab2:tab2)">
      <ion-icon name="person"></ion-icon>
      <ion-label>tab2</ion-label>

      <ion-icon name="bookmarks"></ion-icon>
      <ion-label>tab3</ion-label>
    </ion-tab-button>

  </ion-tab-bar>

</ion-tabs>

我希望当我导航到/ tabs时默认情况下会加载tab1的内容，然后单击tab2图标也应该在tab2page等上显示内容。等等。但是当我进行离子服务时，出现上述错误，然后将/ tabs添加到网址。在这里的任何帮助将不胜感激。谢谢您。

在tabs.router.module.ts

中

删除以下路线上的路径：“标签” ：路线那么代码将是这样的。我正在从文件中粘贴代码

const routes: Routes = [   {
    path: '',
    component: TabsPage,
    children: [
      {
        path: 'tab1',
        loadChildren: () => import('../tab1/tab1.module').then(m => m.Tab1PageModule)
      },
      {
        path: 'tab2',
        loadChildren: () => import('../tab2/tab2.module').then(m => m.Tab2PageModule)
      },
      {
        path: 'tab3',
        loadChildren: () => import('../tab3/tab3.module').then(m => m.Tab3PageModule)
      },
      {
        path: '',
        redirectTo: '/tabs/tab1',
        pathMatch: 'full'
      }
    ]   }, ];

在app-routing.module.ts中，代码将像这样

const routes: Routes = [    {
    path: 'login',
    loadChildren: () => import('./login/login.module').then( m => m.LoginPageModule)   },   {
    path: 'tabs',
    loadChildren: () => import('./tabs/tabs.module').then(m => m.TabsPageModule)   },      {
    path : '',
    redirectTo : 'login',
    pathMatch : 'full'   } ];

嗯，我必须先更新环境，然后使用重大更改指南才能使我的标签页正常工作。以下资源非常有用：

https://forum.ionicframework.com/t/how-to-update-ionic-4-project-to-latest-beta-release/140050/2 https://github.com/ionic-team/ionic/blob/master/CHANGELOG.md#angular-tabs

现在我的离子信息如下：

Ionic:

   ionic (Ionic CLI)             : 4.6.0 (C:\Users\Ken\AppData\Roaming\npm\node_modules\ionic)
   Ionic Framework               : @ionic/angular 4.0.0-rc.0
   @angular-devkit/build-angular : 0.11.4
   @angular-devkit/schematics    : 7.1.4
   @angular/cli                  : 7.1.4

System:

   NodeJS : v10.13.0 (C:\Program Files\nodejs\node.exe)
   npm    : 6.4.1
   OS     : Windows 10

我的package.json看起来像这样：

    "@angular/common": "~7.1.4",
    "@angular/core": "~7.1.4",
    "@angular/forms": "~7.1.4",

    "@angular/compiler-cli": "~7.1.4",
    "@angular/language-service": "~7.1.4",
    "@ionic/angular-toolkit": "~1.2.0",
    "@types/jasmine": "~2.8.8",
    "@types/jasminewd2": "~2.0.3",
    "@types/node": "~10.12.0",
    "codelyzer": "~4.5.0",
    "jasmine-core": "~2.99.1",
    "jasmine-spec-reporter": "~4.2.1",
    "karma": "~3.1.4",
    "karma-chrome-launcher": "~2.2.0",
    "karma-coverage-istanbul-reporter": "~2.0.1",
    "karma-jasmine": "~1.1.2",
    "karma-jasmine-html-reporter": "^0.2.2",

    "ts-node": "~7.0.0",
    "tslint": "~5.12.0",
    "typescript": "3.1.6"
  }

现在，Ionic 4官方文档https://beta.ionicframework.com/上的示例可以按预期工作。
