造成这个错误主要有3个可能的原因：
context上下文不一致
library和name 不一致
生成的dll文件没加入到html文件中
dll.config.js
module.exports = { mode:"production", output: { path:path.resolve(__dirname, '../dist'), filename: '[name].dll.js', library: dllName, //这里需要和DllPlugin option.name 一致 }, entry: { "lib": vendors, }, plugins: [ new webpack.DllPlugin({ path:path.resolve(__dirname,'../dist/manifest.json'), name: dllName, context: __dirname, //上下文必填 }), new CleanWebpackPlugin([`./dist/*.dll.js`,`./dist/*.json`], { root: path.resolve(__dirname, "../") }), ] }
webpack.config.js
new webpack.DllReferencePlugin({ context: __dirname, //这个上下文对应DllPlugin manifest: require('../dist/manifest.json')} ), new AddAssetHtmlPlugin( [ { filepath: "./dist/*.dll.js", //将生成的dll文件加入到index.html中 }, ] ),
