对我来说，这个问题是与capacitor.config.json中的webDir prop ，取代为www，然后它的工作。

改变了我的路由从'家'指向空白的页面，到我需要看到的页面。是一个真正令人困惑的问题，但它躺在我的Angular 应用程序路由完全。

下面是我的代码，指向空白页.

{
    path: '',
    redirectTo: 'home', // It pointed to the blank page
    pathMatch: 'full'
  },
  {
    path: 'recipes', // Used this to run the start page and it worked
    children:[{
      path: '',
      loadChildren: () => import('./recipes/recipes.module').then(m => m.RecipesPageModule)
    },
    {
      path: ':recipeId',
      loadChildren: () => import('./recipes/recipe-detail/recipe-detail.module').then(m => m.RecipeDetailPageModule)
    }
  ]
  m.RecipesPageModule)
  },

使用Angular版本14.1.3和ionic 6.20.1，我通过在文件tsconfig.json的compilerOptions中将编译器目标修改为es2017，解决了空白页问题。
