Webpack 2 source-map不会为javascript和css生成。它甚至没有显示错误。我使用与官方文档相同的语法。我甚至将uglifyJs插件的sourcemap参数添加到了true。有人可以帮帮我吗?
以下是我的webpack配置
const path = require('path');
const ExtractTextPlugin = require("extract-text-webpack-plugin");
const webpack = require('webpack');
const extractSass = new ExtractTextPlugin({
filename: "vendor-styles.css"
});
module.exports = {
entry: './js/app/index.js',
output: {
path: path.resolve(__dirname, "./js/dist/"),
filename: "[name].js"
},
devtool: "source-map",
plugins: [
extractSass,
new webpack.ProvidePlugin({
Promise: 'es6-promise-promise',
$: "jquery",
jQuery: "jquery",
"window.jQuery": "jquery"
}),
new webpack.optimize.CommonsChunkPlugin({
name: 'vendor',
minChunks: function (module) {
return module.context && module.context.indexOf('node_modules') !== -1;
}
}),
new webpack.optimize.UglifyJsPlugin({sourceMap: true})
],
module: {
rules: [{
test: /\.js$/,
exclude: /node_modules/,
loader: "babel-loader",
query: {
presets: [
'env',
'react'
]
}
},
{
test: /\.scss$/,
use: extractSass.extract({
use: [{
loader: "css-loader",
options: {
sourceMap: true,
importLoaders: true
}
}, {
loader: "sass-loader",
options: {
sourceMap: true
}
}],
// use style-loader in development
fallback: "style-loader"
})
},
{
test: /\.css$/,
use: extractSass.extract({
use: [{
loader: "css-loader",
options: {
sourceMap: true,
importLoaders: true
}
}],
// use style-loader in development
fallback: "style-loader"
})
},
{
test: /\.woff(\?v=\d+\.\d+\.\d+)?$/,
use: "url-loader?limit=10000&mimetype=application/font-woff&name=/css/fonts/[name].[ext]"
},
{
test: /\.woff2(\?v=\d+\.\d+\.\d+)?$/,
use: "url-loader?limit=10000&mimetype=application/font-woff&name=/css/fonts/[name].[ext]"
},
{
test: /\.ttf(\?v=\d+\.\d+\.\d+)?$/,
use: "url-loader?limit=10000&mimetype=application/octet-stream&name=/css/fonts/[name].[ext]"
},
{
test: /\.eot(\?v=\d+\.\d+\.\d+)?$/,
use: "file-loader?name=/css/fonts/[name].[ext]"
},
{
test: /\.svg(\?v=\d+\.\d+\.\d+)?$/,
use: "url-loader?limit=10000&mimetype=image/svg+xml&name=/css/fonts/[name].[ext]"
},
{
test: /\.(png|jpg|jpeg|gif)$/,
loader: 'url-loader'
},
]
}
}

我有同样的问题,但我终于通过使用SourceMapDevToolPlugin让webpack为我的.jsx文件吐出源图。我直接从文档中的示例中复制了它; https://webpack.js.org/plugins/source-map-dev-tool-plugin/
希望有所帮助:)

在条目devtool: 'cheap-module-eval-source-map',
之前添加这行代码,然后在调试器中,您应该得到确切的错误行号。
