ng build throws error:"试图找到引导代码,但不能."

Question

在尝试使用我的应用程序时ng-build,我收到以下错误:

试图找到引导代码,但不能.指定静态可分析引导代码或将entryModule传递给plugins选项.

我指定的主文件.angular-cli.json非常简单:

import { NgModule } from '@angular/core';
import { LoginComponent } from './login.component';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic'
import { HttpClientModule } from '@angular/common/http';
import { LoginService } from '../login.service'


@NgModule({
    declarations: [
        LoginComponent
    ],
    imports: [
        BrowserModule,
        FormsModule,
        HttpClientModule
    ],
    providers: [LoginService],
    bootstrap: [LoginComponent]
})
export class AppModule { }

platformBrowserDynamic().bootstrapModule(AppModule);

ng --version 返回以下内容:

Angular: 5.2.5

Answer 1

从大卫的回答中得到线索,我尝试了这个并为我工作.

步骤1:在与main.ts文件相同的文件夹中创建一个名为AppModule.ts的新文件.

第2步:将所有内容从main.ts文件移动到AppModule.ts文件.

第3步:移动后,main.ts文件应该只有这个代码:

import './polyfills';

import {platformBrowserDynamic} from '@angular/platform-browser-dynamic';
import {AppModule} from './AppModule';

platformBrowserDynamic().bootstrapModule(AppModule);

第4步:我的AppModule.ts文件包含此代码.您的AppModule.ts可能根据您编码的内容使用不同的代码.

import {HttpClientModule} from '@angular/common/http';
import {NgModule} from '@angular/core';
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';
import {BrowserModule} from '@angular/platform-browser';
import {YOURCustomCode} from './app/YOURCustomCode';

@NgModule({
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    FormsModule,
    HttpClientModule,
    DemoMaterialModule,
    MatNativeDateModule,
    ReactiveFormsModule,
  ],
  entryComponents: [YOURCustomCode],
  declarations: [YOURCustomCode],
  bootstrap: [YOURCustomCode],
  providers: []
})
export class AppModule {}

步骤5:运行命令ng serve,它现在编译和构建时没有错误引导程序模块错误.
