angular - Webpack错误: angular_compiler_plugin - Cannot read property 'environment' of undefined

Question

我正在尝试部署我的应用程序，但当它执行命令时:

webpack.js --config webpack.config.vendor.js --env.prod

我收到以下错误:

angular_compiler_plugin.ts:580 compiler.hooks.environment.tap('angular-compiler', () => {
                                                                            ^
TypeError: Cannot read property 'environment' of undefined

按照 this article 的“调整”部分的建议，我已将 AoTPlugin 替换为 AngularCompilerPlugin - 我在整个第一个应用程序创建过程中都遵循了这一点 - 因为 Aot 由于它的 Angular 5 不兼容而给我带来了同样的错误，但现在我遇到了这个错误，而且我真的在解决它时迷失了方向。

有人知道如何解决这个问题吗？

下面是我的代码

这是我的 webpack.config.js 内容:

const path = require('path');
const webpack = require('webpack');
const merge = require('webpack-merge');
const AngularCompilerPlugin = require('@ngtools/webpack').AngularCompilerPlugin;
const CheckerPlugin = require('awesome-typescript-loader').CheckerPlugin;
var nodeExternals = require('webpack-node-externals');

module.exports = (env) => {
    // Configuration in common to both client-side and server-side bundles
    const isDevBuild = !(env && env.prod);
    const sharedConfig = {

        stats: { modules: false },
        context: __dirname,
        resolve: { extensions: [ '.js', '.ts' ] },
        output: {
            filename: '[name].js',
            publicPath: 'dist/' // Webpack dev middleware, if enabled, handles requests for this URL prefix
        },
        module: {

                    }]
                }
            ]
        },
        plugins: [new CheckerPlugin()]
    };

    // Configuration for client-side bundle suitable for running in browsers
    const clientBundleOutputDir = './wwwroot/dist';
    const clientBundleConfig = merge(sharedConfig, {

        output: { path: path.join(__dirname, clientBundleOutputDir) },
        plugins: [
            new webpack.DllReferencePlugin({

                manifest: require('./wwwroot/dist/vendor-manifest.json')
            })
        ].concat(isDevBuild ? [
            // Plugins that apply in development builds only
            new webpack.SourceMapDevToolPlugin({
                filename: '[file].map', // Remove this line if you prefer inline source maps
                moduleFilenameTemplate: path.relative(clientBundleOutputDir, '[resourcePath]') // Point sourcemap entries to the original file locations on disk
            })
        ] : [
            // Plugins that apply in production builds only
            new webpack.optimize.UglifyJsPlugin(),
            new AngularCompilerPlugin({
                tsConfigPath: './tsconfig.json',
                entryModule: path.join(__dirname, 'ClientApp/app/app.browser.module#AppModule'),
                exclude: ['./**/*.server.ts']
            })
        ])
    });

    // Configuration for server-side (prerendering) bundle suitable for running in Node
    const serverBundleConfig = merge(sharedConfig, {
        resolve: { mainFields: ['main'] },
        entry: { 'main-server': './ClientApp/boot.server.ts' },
        plugins: [
            new webpack.DllReferencePlugin({
                context: __dirname,

                sourceType: 'commonjs2',
                name: './vendor'
            })
        ].concat(isDevBuild ? [] : [

                entryModule: path.join(__dirname, 'ClientApp/app/app.server.module#AppModule'),
                exclude: ['./**/*.browser.ts']
            })
        ]),
        output: {
            libraryTarget: 'commonjs',
            path: path.join(__dirname, './ClientApp/dist')
        },

        //esclusione moduli node
        target: 'node',
        externals: [nodeExternals()], // in order to ignore all modules in node_modules folder
        devtool: 'inline-source-map'
    });

    return [clientBundleConfig, serverBundleConfig];
};

问题出在这种依赖性上 "@ngtools/webpack": "^6.0.0-rc.2.4", 你的解决方案就在这里 https://github.com/angular/angular-cli/issues/9793 基本上这样做 npm install @ngtools/webpack@1.10.2 --only=dev
