这是我的问题：
当我使用contenthash作为捆绑的文件名时，生产构建失败。
我遇到以下错误：
Unhandled rejection Error: "." is not in the SourceMap.

这是我的webpack配置。
webpack.prod.js
const merge = require('webpack-merge');
const common = require('./webpack.common.js');
const webpack = require('webpack');
const path = require('path');
const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;
module.exports = merge(common, {
mode: 'production',
devtool: 'source-map',
output: {
filename: '[name].[contenthash:5].js',
// filename: '[name].[hash:5].js',
path: path.resolve(__dirname, 'public'),
publicPath: '/'
},
plugins:[
// new webpack.IgnorePlugin(/fuse.js/),
new webpack.HashedModuleIdsPlugin(),
new BundleAnalyzerPlugin()
],
// Basic otimization: Single runtimeChunk + vendorsChunk
optimization:{
runtimeChunk: 'single',
splitChunks: {
cacheGroups: {
vendor: {
test: /[\\/]node_modules[\\/]/,
name: 'vendors',
chunks: 'all'
}
}
}
}
});

[hash:5]而不是[contenthash:5]，它将生成无错误的内容。devtool: 'none'而不是devtool: 'source-map'，它的构建也不会出错。fuse.js插件。它也可以正确构建。
new webpack.IgnorePlugin(/fuse.js/), 由于我忽略Fuse.js软件包时错误消失了，因此我认为这是相关的。
可能会发生什么？有人遇到过这样的问题吗？
