我正在尝试使用角度为1.6和5的混合应用程序 . 手动引导有效 . 一旦我尝试引导混合应用程序,我就会收到以下错误:

compiler.js?7e34:466未捕获错误:无法解析AppModule的所有参数:(?) . at syntaxError(eval at(app.bundle.js:1852),:684:34)at CompileMetadataResolver._getDependenciesMetadata(eval at(app.bundle.js:1852),:15765:35)at CompileMetadataResolver._getTypeMetadata(eval at( app.bundle.js:1852),:15600:26)at CompileMetadataResolver.getNgModuleMetadata(eval at(app.bundle.js:1852),:15399:24)at JitCompiler._loadModules(eval at(app.bundle.js: 1852),:33760:87)在JitCompiler._compileModuleAndComponents(eval at(app.bundle.js:1852),:33721:36)at JitCompiler.compileModuleAsync(eval at(app.bundle.js:1852),:33637: 37)at CompilerImpl.compileModuleAsync(eval at(app.bundle.js:1864),:245:49)at PlatformRef.bootstrapModule(eval at(app.bundle.js:229),:5646:25)at eval(eval) at(app.bundle.js:827),:76:53)

app.ts

platformBrowserDynamic().bootstrapModule(AppModule);

app.module.ts

import {NgModule} from '@angular/core';
import {BrowserModule} from '@angular/platform-browser';
import {UpgradeModule} from '@angular/upgrade/static';

@NgModule({
    imports: [
        BrowserModule,
        UpgradeModule
    ]
})
export class AppModule {
    constructor(private upgrade: UpgradeModule) {
    }

    ngDoBootstrap() {
        this.upgrade.bootstrap(document.documentElement, ['myApp']);
    }
}

tsconfig.json

{
  "compileOnSave": false,
  "compilerOptions": {
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "module": "commonjs",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es5",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2017",
      "dom"
    ]
  }
}

我正在使用webpack . 这是我配置的一部分:

resolve: {
    extensions: ['.js', '.ts'],
    alias: {
        "@angular/upgrade/static": "@angular/upgrade/bundles/upgrade-static.umd.js"
    }
},

module: {
    rules: [
        {
            test: /\.ts$/,
            loader: 'ts-loader',
            exclude: '/node_modules'
        },

    至于代码你've shared everything seems to be in order. It could be though, that you'再使用另一个注释库's clashing with Angular'的装饰器 . 例如,如果您使用angular-ts-decorators,肯定会导致这样的问题 .

    如果是这种情况 - 删除其他注释库(现在应该是冗余的)并使用Angular的注释 .

    在我的情况下加载JS后,它开始工作:

    ./node_modules/core-js/client/shim.min.js
    ./node_modules/zone.js/dist/zone.js
