Question

我已经将我的角度项目版本6迁移到了9，但直到8 迁移进行顺利，并且工作正常。一旦我从v8迁移到v9 我的项目在屏幕上空白，并且IVY没有显示任何错误在构建和chrome控制台上也清除没有错误我也使用测试组件进行测试，并且路由器插座正常工作，但是在我常春藤的项目组件一次编译每个代码，所以我无法获取受影响的区域包或代码进行调试

提前谢谢。

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);

我遇到了同样的问题，对我来说，这是Devextreme的问题：

https://github.com/DevExpress/devextreme-angular/issues/975#issuecomment-580172291

从19.2.5版本开始，我们支持IVY编译器。

我将确保您所有的软件包都支持IVY并进行相应升级。

版本9 IVY编译器的角度项目迁移问题
