版本9的Angular项目迁移问题与IVY编译器相关

angularmigrationangular9angular-ivy

我已经将我的 Angular 项目从版本6迁移到9，但在迁移至8时一切顺利并且它可以正常工作。但当我从v8迁移到v9时，我的项目在屏幕上变空了，而IVY在构建时没有显示任何错误，并且Chrome控制台也没有错误。我已经测试了测试组件并发现路由出口有效，但是在我的项目组件上，因为ivy会一次性编译所有代码，所以我无法获取受影响的区域包或代码进行调试。

提前致谢。

main.ts看起来像这样

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

import { AppModule } from './app/app.module';
import { environment } from './environments/environment';

if (environment.production) {
  enableProdMode();
}

platformBrowserDynamic().bootstrapModule(AppModule);

请您能否添加一些逗号，并发布相关的代码，例如 package.json、tsconfig、主模块和路由？ - Jacopo Sciampi
是的，我已经在路由器中使用了所有逗号，每当我将路由组件更改为我的新创建的TestComponent时，路由工作正常，但我的项目代码重定向到路径匹配不起作用 { path: 'xx', component: xx},{ path: 'xx', component: xx, canActivate: [WorkflowGuard] }, { path: 'xx', component: xx, canActivate: [WorkflowGuard] }, { path: 'xx', component: xx}, { path: '', redirectTo: '/xx', pathMatch: 'full' }, { path: '**', redirectTo: '/xx'} - Abhishek Sharma
我是说在你的问题中应该使用逗号。另外，请将相关代码格式化后添加到你的问题中。 - Jacopo Sciampi
@JacopoSciampi，请在上方找到相关代码。 - Abhishek Sharma

我仍然在使用新的IVY遇到问题。 当我使用ng build/serve --prod运行Angular8代码库时，它可以工作，但是在Angular9代码库中，只有ng server正在运行，当我添加--prod到serve或build时，它无法工作。 - Abhishek Sharma
我在Chrome上经常遇到错误polyfills.9b85908313a7766a001a.js:1 Unhandled Promise rejection: Angular JIT编译失败：未加载'@angular/compiler' 不建议在生产环境中使用JIT编译！请考虑使用AOT模式。 -您是否使用'@angular/platform-browser-dynamic'或'@angular/platform-server'引导？ -或者在引导之前为编译器提供'import "@angular/compiler";'。;区域：<root>；任务：Promise.then；值：错误：Angular JIT编译失败：未加载'@angular/compiler' - Abhishek Sharma
