我有这个 > 5 岁的 Angular 1.5.8 项目，由其他人开发，使用 webpack 2.7.0。它目前无法构建。该错误似乎在第一个.css文件中遇到，恰好是angular-material.css：
[96] ./~/angular-material/angular-material.css 1.04 kB {0} [built] [failed] [1 error]
再往下走，我收到两个警告：
WARNING in DedupePlugin: This plugin was removed from webpack. Remove it from your configuration.
WARNING in webpack: Using NoErrorsPlugin is deprecated.
Use NoEmitOnErrorsPlugin instead.
...然后是一堆类似的错误（超过 500 行），其中我只介绍第一个：
ERROR in ./src/styles/main.less

我尝试的第一件事是^从 package.json 中的所有依赖项中删除所有组合子，如下所示：
{
"name": "***",
"version": "1.0.0",
"description": "***",
"main": "app.js",
"scripts": {

},

}
}
...而且，坦率地说，当我确保使用其依赖项的那些确切版本时，我期待它能够构建。但错误仍然存在。
我尝试的第二件事是降级节点。我尝试使用13.11.0（最初）12.18.3、8.11.3和5.12.0.
一般来说，我对 webpack 不是很好，但说到v2.*我完全迷路了。
这是 webpack 的配置：
'use strict';
//Modules
const webpack = require('webpack');
const path = require('path');
const ExtractTextPlugin = require("extract-text-webpack-plugin");
const HtmlWebpackPlugin = require("html-webpack-plugin");
//Environment
const env = process.env.npm_lifecycle_event;
var isTest = env === 'test' || env === 'test-watch';
var isProd = env === 'build';
module.exports = {
devtool: 'source-map',
entry: {
app: './src/app/app.js'
},
devServer: {
outputPath: path.join(__dirname, 'src'),
contentBase: "./src"
},
output: {
path: path.resolve(__dirname, 'dist'),
publicPath: isProd ? '' : 'http://localhost:8080/',
filename: isProd ? 'js/[name].[hash].js' : 'js/[name].bundle.js',
chunkFilename: isProd ? 'js/[name].[hash].js' : 'js/[name].bundle.js'
},
resolve: {
// you can load named modules from any dirs you want.
// attempts to find them in the specified order.
modules: [
'./src/lib',
'node_modules'

},
module: {

{

loader: 'html-loader'
},
//Transpile ES6 to ES5
{

include: path.join(__dirname, 'src'),
exclude: /node_modules/,
loader: 'babel-loader',
query: {
presets: [

]
}
},
//Extract Normal CSS

},
//Bundle Less into CSS Code

},
//Images
{
test: /\.(png|jpg|jpeg|gif|svg|woff|woff2|ttf|eot)$/,
loader: 'file-loader'
}
]
},
plugins : (() => {
let plugins = [];
//Render Index.html, Extract CSS
plugins.push(
new HtmlWebpackPlugin({
template: './src/index.html',
inject: 'body'
}),
// Write out CSS bundle to its own file:
new ExtractTextPlugin({
filename: 'css/styles.css',
allChunks: true})
);
//If prod do extra stuff
if (isProd) {
plugins.push(
// Only emit files when there are no errors
new webpack.NoErrorsPlugin(),
// Dedupe modules in the output
new webpack.optimize.DedupePlugin(),
// Minimize JS
new webpack.optimize.UglifyJsPlugin({
compress: {
warnings: false
},
output: {
comments: false
},
sourceMap: true
})
/*new CopyWebpackPlugin([{
from: __dirname + '/src/public'
}])*/
)
}
return plugins;
})()
};
我花了相当多的时间阅读与 webpack 及其加载器相关的 github 问题，但没有遇到任何可以提示我走向正确方向的东西。
感谢您花时间研究此问题以及您可能提出的任何建议。
