webpack dllPlugin踩坑

在chainWebpack中配置

chainWebpack:config => {
    const files = fs.readdirSync(path.resolve(__dirname, './dll'))
    for (let i = 0; i < files.length; i++) {
        if (/.*\.dll.js/.test(files[i])) {
            config.plugin('AddAssetHtmlWebpackPlugin' + i).use(require('add-asset-html-webpack-plugin'), [{
              filepath: path.resolve(__dirname, 'dll', files[i])
            }])
          }
         if (/.*\.manifest.json/.test(files[i])) {
            config.plugin('DllReferencePlugin' + i).use(require('webpack/lib/DllReferencePlugin'), [{
              context: __dirname,
              manifest: path.resolve(__dirname, 'dll', files[i])
            }])
          }
    }
}

注：本来for循环是用forEach来写的，但是报Cannot assign to read only property 'exports' of object '#
