在Android中构建之后，选项卡组件在Ionic电容应用程序中不呈现

Question

我的Ionic电容移动应用程序在使用Android系统时遇到了一个非常有趣的问题。

我有一个非常简单的应用程序，它使用Tabs组件在主页和信息页之间导航。当使用Live在我的机器上的dev服务器或设备上运行应用程序时，应用程序功能正常，出现选项卡，我可以按预期在页面之间导航。

当我将这个应用程序从Android直接运行到我的设备上，或者生成一个APK/Bundle并在我的设备上执行它时，问题就出现了。在安装了生成的APK/Bundle之后运行该应用程序时，没有呈现选项卡，我不知道为什么会这样？我尝试过发行版和调试版本，它们都显示了相同的问题。

任何帮助或建议都是非常感谢的！

使用Live 运行dev的

​

运行APK的

很抱歉，因为我无法捕获此图的控制台日志，但正如您所看到的，这里没有呈现Tabs。

如果我只是在Android上运行这个应用程序，也会发生同样的情况。

如果你把你收到的错误寄给我们，那应该是件好事。但让我解释一下。这可能是tabs-routing.module.ts文件上的一个错误。因此，让字段path: ''在路由上为空，如下所示：

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'
      }
    ]
  },
  {
    path: '',
    redirectTo: '/tabs/tab1',
    pathMatch: 'full'
  }
];
