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
},
]
),
