我正在尝试在Android上构建NativeScript应用。该应用程序编译时没有错误，但是当我尝试在模拟器中进行构建时，出现以下错误：
“错误：缺少主条目。无法启动应用程序。请验证应用程序引导程序。”
我们已经尝试删除node_modules和package-lock.json并运行yarn / npm install，但似乎没有任何作用。
这是我的package.json的样子：

将此示例代码添加到main.ts文件中。
import { platformNativeScriptDynamic } from "nativescript-angular/platform";
import { enableProdMode } from '@angular/core';
import { AppModule } from "./app/app.module";
enableProdMode();
platformNativeScriptDynamic().bootstrapModule(AppModule);
