Angular 2 AOT-无法解析$$ _ gendir ... ngfactory [英] Angular 2 AOT - Can't resolve $$_gendir...ngfactory

问题描述

https://github.com/stefankendall/broken-aot

我正在尝试使用webpack和gulp设置一个简单的AOT angular 2构建.在我创建的最小示例中，我具有以下内容:

I'm trying to setup a simple AOT angular 2 build with webpack and gulp. In my minimal example I've created, I have the following:

./src/app/components -主应用程序使用的组件，一个单独的ngmodule ./src/app/examples -主应用程序

./src/app/components - components used by the main application, a separate ngmodule ./src/app/examples - the main application

ERROR in ./src/index.ts
Module not found: Error: Can't resolve './../$$_gendir/src/app/examples/app.module.ts.ngfactory' in '/Users/username/workpath/projectname/src'
 @ ./src/index.ts 8:32-98

根据先前的帖子， index.ts 看起来像这样:

Based on a previous post, index.ts looks like this:

import 'core-js/client/shim';
import 'zone.js/dist/zone';

import '@angular/common';
import 'rxjs';

import {enableProdMode} from '@angular/core';
import {platformBrowserDynamic} from '@angular/platform-browser-dynamic';
import {AppModule} from './app/examples/app.module';

declare let process: any;
if (process.env.NODE_ENV === 'production') {
  enableProdMode();
} else {
  Error['stackTraceLimit'] = Infinity; // tslint:disable-line:no-string-literal
  require('zone.js/dist/long-stack-trace-zone'); // tslint:disable-line:no-var-requires
}

platformBrowserDynamic().bootstrapModule(AppModule);

这将从 ./src/app/examples/app.module.ts 加载 AppModule ，如下所示:

This loads AppModule from ./src/app/examples/app.module.ts, which looks like this:

import {CUSTOM_ELEMENTS_SCHEMA, NgModule} from '@angular/core';
import {FormsModule} from '@angular/forms';
import {BrowserModule} from '@angular/platform-browser';

import {MainComponent} from './MainComponent';
import {AppComponent} from './AppComponent';
import {routing} from './routes';
import {ComponentsModule} from '../components/index';

@NgModule({
  imports: [
    BrowserModule,
    ComponentsModule,
    FormsModule,
    routing
  ],
  declarations: [
    AppComponent,
    MainComponent
  ],
  bootstrap: [AppComponent],
  schemas: [CUSTOM_ELEMENTS_SCHEMA]
})
export class AppModule {
}

在没有AOT的情况下在本地运行可以正常工作，但是尝试使用以下Webpack配置进行AOT构建会产生错误:

Running locally without AOT works fine, but attempting an AOT build with the following webpack config yields the error:

const webpack = require('webpack');
const conf = require('./gulp.conf');
const path = require('path');

const HtmlWebpackPlugin = require('html-webpack-plugin');
const FailPlugin = require('webpack-fail-plugin');

const autoprefixer = require('autoprefixer');
const AotPlugin = require('@ngtools/webpack').AotPlugin;
const CopyWebpackPlugin = require('copy-webpack-plugin');

module.exports = {

        },
        tslint: {

      $: 'jquery',
      jQuery: 'jquery',

      Tether: 'tether'
    }),
    new AotPlugin({
      tsConfigPath: './tsconfig.json',
      entryModule: path.resolve('./src/app/examples/app.module.ts#AppModule')
    }),
    new webpack.optimize.UglifyJsPlugin({
      output: {comments: false},
      compress: {unused: true, dead_code: true, warnings: false} // eslint-disable-line camelcase
    })
  ],
  output: {
    path: path.join(process.cwd(), conf.paths.dist, 'aot'),
    filename: '[name]-[hash].js'
  },
  resolve: {
    extensions: [
      '.webpack.js',
      '.web.js',
      '.js',
      '.ts'
    ]
  }
};

我想念什么?

推荐答案

AOT已损坏.不要打扰

AOT is broken. Don't bother.

如果您从一开始就拥有它就可以了.但是，转换项目几乎是不可能的.

It's fine if you have it from the start. Converting a project is nearly impossible, however.
