我无法使我的Webpack发出CSS源地图。我已经将sourcemap设置为:在任何可能的地方都正确,并且没有任何影响,并且所有在线解决方案都建议使用此插件或其他插件配置,但是我没有任何其他插件,它是超级简单的webpack.config.js
这是我的webpack.config.js:
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
var path = require("path");
module.exports = {
entry: "./main.js",
output: {
path: path.resolve(__dirname, "dist"),
filename: "bundle.js",
publicPath: "/",
sourceMapFilename: '[file].map'
},
devtool: 'source-map',
module: {
rules: [{
test: /\.js$/,
use: {
loader: "babel-loader",
options: {
presets: ["es2015"],
sourceMap: true
}
}
},
{
test: /\.scss$/,
use: [{
loader: MiniCssExtractPlugin.loader,
options: {
publicPath: '/',
sourceMap: true,
hmr: process.env.NODE_ENV === 'development',
},
},
{
loader: "css-loader",
options: {
sourceMap: true
}
},
{
loader: "sass-loader",
options: {
sourceMap: true
},
}
]
},
{
test: /\.(png|woff|woff2|eot|ttf|svg|jpg)$/,
use: [{
loader: 'url-loader',
options: {
name: 'images/[hash]-[name].[ext]'
}
}]
}
]
},
plugins: [
new MiniCssExtractPlugin({
filename: '[name].css',
chunkFilename: '[id].css',
ignoreOrder: false, // Enable to remove warnings about conflicting order
sourceMap: true
}),
],
};
我需要在开发人员模式下使用此源映射,但是只有两个文件会发出main.css和bundle.js。
答案 0 :(得分:0)
对于那些也为此感到困惑的人,下面的webpack.config.js是用于在开发人员模式下放置样式的源地图的正确配置。在开发模式下,必须包含Bundle.js,在生产模式下,需要将custom.min.css添加到HTML文档中。
编辑:不幸的是,这也可能是错误的。现在,在未对Webpack或节点进行任何更改的情况下,sourcemap不会生成:/有时有效,有时却无效。在webpack或某些插件中都存在一些错误,无论哪种方式,这都是一个严重的错误,但是它是webpack,所以我并不感到惊讶...
编辑2:现在,我看到问题仅在Firefox中,Chrome和Opera具有正确的地图。
