Webpack cacheGroups新增chunk后页面空白问题如何解决？

Question

为什么cacheGroups新增新的chuck后打包打开页面空白？

cacheGroups: {
                                libs: {
                                    name: 'chunk-libs',
                                    test: /[\\/]node_modules[\\/]/,
                                    priority: 10,
                                    chunks: 'initial' // only package third parties that are initially dependent
                                },
                                elementUI: {
                                    name: 'chunk-elementUI', // split elementUI into a single package
                                    priority: 20, // the weight needs to be larger than libs and app or it will be packaged into libs or app
                                    test: /[\\/]node_modules[\\/]_?element-ui(.*)/ // in order to adapt to cnpm
                                },
                                commons: {
                                    name: 'chunk-commons',
                                    test: resolve('src/components'), // can customize your rules
                                    minChunks: 3, //  minimum common number
                                    priority: 5,
                                    reuseExistingChunk: true
                                },
                                libs2: {
                                    name: 'chunk-libs2',
                                    test: /[\\/]src[\\/]utils[\\/]/,
                                    chunks: 'all',
                                    enforce: true
                                }
                            }

libs2是新增的chunck，加了之后打包出来的页面就空白了，请问应该怎么修改配置？
