Webpack不会生成/重新创建dist / vendor.css

标签: angular webpack aspnetcoretemplatepack

我有一个使用aspnet核心模板创建的angular2 +项目。我使用asp net core提供的模板开始了项目。我已经将这些软件包更新到Angular 5.1。 我最近买了一台新笔记本电脑,所以我在新机器上做了一个克隆,但是当我运行webpack --config webpack.config.vendor.js时它没有生成vendor.css,它会抛出这个错误: enter image description here

这是我的webpack.config.vendor.js,我几乎没有改变:

const path = require('path');
const webpack = require('webpack');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const merge = require('webpack-merge');

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' }
            ]

                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.IgnorePlugin(/^vertx$/) // Workaround for https://github.com/stefanpenner/es6-promise/issues/100
        ]
    };

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

    return [clientBundleConfig, serverBundleConfig];
}

我在上一台机器上的项目确实有vendor.css。

对于从Angular4.x更新到5.x时出现类似问题的任何人,我只需添加此内容:

    new webpack.ContextReplacementPlugin(/\@angular(\\|\/)core(\\|\/)esm5/, path.join(__dirname, './src')),

配置看起来不错。可能会升级供应商模块并且不再require css了吗?

要检查的事情

  1. 确保您的新笔记本电脑具有完全相同的版本 供应商模块与旧机器模块相同。
  2. 从申请方面来看, 删除对vendor.css的引用,看看是否有任何问题 在UI。
