目前我正在尝试将angular js项目迁移到angular（11+）。因为这是一个大型项目，我想以混合模式引导angularjs和angularjs，这样我就可以逐步升级所有东西。
在那之前我没有用过webpack。在创建webpack包并尝试加载应用程序后，我发现以下错误，一些@angular文件找不到。例如：
得到https://localhost/learn/templates/0/node_modules/@Angular /核心/esm2015/src/core网络：：错误404（未找到）
虽然这些文件的路径是正确的，但我只发现它们缺少.js文件扩展名。

这是我的webpack.config.js

module.exports = {
entry: "./main.ts",
output: {
    filename: "./angular/bundle/bundledProjectModule.js"
},
resolve: {
    extensions: [".webpack.js", ".web.js", ".ts", ".tsx", ".js"]
},
module: {
    rules: [
        //all files with a '.ts' or '.tsx' extension will be handled by 'ts-loader'
        { test: /\.tsx?$/, use: "ts-loader" }
    ]
}
};

这是我的tsconfig.json：

{  
  "compilerOptions": {
    "baseUrl": "",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "module": "ESNext",
    "target": "es5",
    "sourceMap": true,
    "moduleResolution": "node",
    "lib": ["dom", "es2016", "es2019.object"]
  },  
  "typeRoots": [
    "./node_modules/@types"
  ],
  "exclude": [
    "node_modules"
  ]
}

这是我的main.ts文件：

export class AppModule {
    // Override Angular bootstrap so it doesn't do anything
    ngDoBootstrap() {
    }
}

// Bootstrap using the UpgradeModule
platformBrowserDynamic().bootstrapModule(AppModule).then(platformRef => {
    console.log("Bootstrapping in Hybrid mode with Angular & AngularJS");
    const upgrade = platformRef.injector.get(UpgradeModule) as UpgradeModule;
    upgrade.bootstrap(document.body, ['learn']);
});
