  }
}

我的 webpack.config.vendor.js：

const path = require('path');
const webpack = require('webpack');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const merge = require('webpack-merge');
const treeShakableModules = [
    '@angular/animations',
    '@angular/common',
    '@angular/compiler',
    '@angular/core',
    '@angular/forms',
    '@angular/http',
    '@angular/platform-browser',
    '@angular/platform-browser-dynamic',
    '@angular/router',
    'zone.js',
    '@angular/cdk'
];
const nonTreeShakableModules = [
    'hammerjs/hammer',
    'bootstrap',
    'bootstrap/dist/css/bootstrap.css',
    'es6-promise',
    'es6-shim',
    'event-source-polyfill',
    'jquery',
    '@angular/material/prebuilt-themes/indigo-pink.css',


];
const allModules = treeShakableModules.concat(nonTreeShakableModules);

module.exports = (env) => {
    const extractCSS = new ExtractTextPlugin('vendor.css');
    const isDevBuild = !(env && env.prod);
    const sharedConfig = {
        stats: { modules: false },
        resolve: { extensions: [ '.js' ] },
        module: {
            rules: [
                { test: /\.(png|woff|woff2|eot|ttf|svg)(\?|$)/, use: 'url-loader?limit=100000' }
            ]
        },
        output: {
            publicPath: 'dist/',
            filename: '[name].js',
            library: '[name]_[hash]'
        },
        plugins: [
            new webpack.ProvidePlugin({ $: 'jquery', jQuery: 'jquery' }), // Maps these identifiers to the jQuery package (because Bootstrap expects it to be a global variable)
            new webpack.ContextReplacementPlugin(/\@angular\b.*\b(bundles|linker)/, path.join(__dirname, './ClientApp')), // Workaround for https://github.com/angular/angular/issues/11580
            new webpack.ContextReplacementPlugin(/angular(\\|\/)core(\\|\/)@angular/, path.join(__dirname, './ClientApp')), // Workaround for https://github.com/angular/angular/issues/14898
            new webpack.IgnorePlugin(/^vertx$/) // Workaround for https://github.com/stefanpenner/es6-promise/issues/100
        ]
    };

    const clientBundleConfig = merge(sharedConfig, {
        entry: {
            // To keep development builds fast, include all vendor dependencies in the vendor bundle.
            // But for production builds, leave the tree-shakable ones out so the AOT compiler can produce a smaller bundle.
            vendor: isDevBuild ? allModules : nonTreeShakableModules
        },
        output: { path: path.join(__dirname, 'wwwroot', 'dist') },
        module: {
            rules: [
                { test: /\.css(\?|$)/, use: extractCSS.extract({ use: isDevBuild ? 'css-loader' : 'css-loader?minimize' }) }
            ]
        },
        plugins: [
            extractCSS,
            new webpack.DllPlugin({
                path: path.join(__dirname, 'wwwroot', 'dist', '[name]-manifest.json'),
                name: '[name]_[hash]'
            })
        ].concat(isDevBuild ? [] : [
            new webpack.optimize.UglifyJsPlugin()
        ])
    });

    const serverBundleConfig = merge(sharedConfig, {
        target: 'node',
        resolve: { mainFields: ['main'] },
        entry: { vendor: allModules.concat(['aspnet-prerendering']) },
        output: {
            path: path.join(__dirname, 'ClientApp', 'dist'),
            libraryTarget: 'commonjs2',
        },
        module: {
            rules: [ { test: /\.css(\?|$)/, use: ['to-string-loader', isDevBuild ? 'css-loader' : 'css-loader?minimize' ] } ]
        },
        plugins: [
            new webpack.DllPlugin({
                path: path.join(__dirname, 'ClientApp', 'dist', '[name]-manifest.json'),
                name: '[name]_[hash]'
            })
        ]
    });

    return [clientBundleConfig, serverBundleConfig];
}

还有我的 app.shared.module.ts：

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { RouterModule } from '@angular/router';

import { AppComponent } from './components/app/app.component';
import { NavMenuComponent } from './components/navmenu/navmenu.component';
import { HomeComponent } from './components/home/home.component';
import { FetchDataComponent } from './components/fetchdata/fetchdata.component';
import { CounterComponent } from './components/counter/counter.component';

import { MatButtonModule } from '@angular/material/button';


@NgModule({
    declarations: [
        AppComponent,
        NavMenuComponent,
        CounterComponent,
        FetchDataComponent,
        HomeComponent
    ],
    imports: [
        CommonModule,
        HttpModule,
        FormsModule,
        RouterModule.forRoot([
            { path: '', redirectTo: 'home', pathMatch: 'full' },
            { path: 'home', component: HomeComponent },
            { path: 'counter', component: CounterComponent },
            { path: 'fetch-data', component: FetchDataComponent },
            { path: '**', redirectTo: 'home' }
        ]),
        MatButtonModule
    ]
})
export class AppModuleShared {
}

我的 vendor.config 编译得很好。当我在 VS2017 中调试项目时，我得到了这个错误：

NodeInvocationException：由于错误，预渲染失败：错误：在 webpackMissingModule 上找不到模块“rxjs/operators/take” (C:\Users\Mike\Source\MyProj\ClientApp\dist\main-server.js:15733:140)

任何关于我应该在哪里引用 rxjs 模块的帮助将不胜感激。

【问题讨论】：

您是否尝试将@angular/material 添加到webpack.config.vendor.js 中的treeShakableModules 常量？我猜这个。 :)
我有，这会导致 webpack.config.vendor.js 无法编译。错误几乎相同：找不到模块：错误：无法解析`'rxjs/operators/map in ..\node_modules\@angular\cdk\esm5'

标签： angular asp.net-core angular-material asp.net-core-2.0

【解决方案1】：

从package.json可以看出，@angular/material有如下依赖：

"rxjs": "^5.5.5"

你的package.json 中有"rxjs": "5.4.2"，这显然有点落后。我实际上为 flex-layout angular 包找到了 Github issue，它建议将 rxjs 升级到 5.5 解决了该包中的相同问题。我刚刚使用您的设置进行了尝试，并且可以确认它可以使用上述 5.5.5 工作。

编辑：安装更新版本后，您需要让 webpack 以正确的顺序重新构建。您可以通过项目的解决方案级重建来实现这一点，但如果没有，您可以运行以下命令来强制 webpack 正确构建：

webpack --config webpack.config.vendor.js
webpack

您可能没有全局安装webpack - 如果没有，您可以使用以下（假设是 Windows）：

.\node_modules\.bin\webpack --config webpack.config.vendor.js
.\node_modules\.bin\webpack

【讨论】：

导致新错误：NodeInvocationException：预渲染失败，因为错误：TypeError：无法读取未定义的属性“原型”。您是否使用与我的 package.json 中相同版本的材料和角度？
您是否可以发布指向工作 sln 的链接？我已经摆弄了一天多没有运气。
实际上，我设法重现了同样的错误。我添加了一个编辑来解释我是如何解决这个问题的。如果这不起作用，我将提供 Github 存储库。
是的，我需要一个 git。我的 webpack.config.vendor.js 编译得很好，但是当我运行 webpack 时，它会出现与 OP 中提到的相同的错误。
大声笑..我死在这里。你的工作没有问题，我复制并粘贴了上面提到的 3 个文件，我的失败了。哦，好吧，我很感激帮助。我可以查看我的文件，我一定是遗漏了什么。

【解决方案2】：

在 ASP.net Core 2.0 中使用默认安装的节点包添加最新版本的 Angular Material 解决包依赖关系更加困难和耗时。

在 package.json 中使用以下版本的角度材料

"@angular/cdk": "^2.0.0-beta.12"

"@angular/material": "^2.0.0-beta.12"

然后运行下面的命令来安装它。

npm install --save
