Webpack 2.7.0 LoaderRunnerError： 模块 '*node_moduleslessindex.js' 不是加载器(必须具有正常或俯仰功能)

Question

我有这个>5年前别人开发的Angular 1.5.8项目，使用的是webpack2.7.0。它当前无法构建。错误似乎是在第一个.css文件中遇到的，该文件恰好是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(，其中我只介绍了第一个：

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：

}

坦率地说，当我确保使用了它的依赖关系的确切版本时，我正期待着它的构建。但错误依然存在。

我尝试的第二件事是降级node。我尝试用13.11.0(最初(、12.18.3、8.11.3和5.12.0构建它。

一般来说，我对webpack不太好，但当谈到v2.*时，我完全迷失了方向。

以下是webpack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: [

},

include: path.join(__dirname, 'src'),
exclude: /node_modules/,

query: {

]
}
},

},
//Bundle Less into CSS Code

loader: ExtractTextPlugin.extract('css-loader?sourceMap!autoprefixer!less?sourceMap')
},
//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([{

}])*/
)
}
return plugins;
})()
};

我花了相当多的时间阅读与webpack及其加载程序相关的github问题，但没有发现任何能提示我走向正确方向的内容。

感谢您花时间对此进行研究，以及您可能提出的任何建议。

Answer 1

如果问题仅与特定模块有关，则可以执行以下操作，

1-重新安装该特定模块(删除后安装(。

2-尝试升级或降级模块版本。

考虑到该项目目前已有5年历史，我想更改版本可能会解决您的问题。
