How to Solve Webpack CacheGroups Error 

[webpack-cli] Invalid configuration object. Webpack has been initialized using a configuration object that does not match the API schema.
 - configuration.optimization.splitChunks has an unknown property 'CacheGroups'. These properties are valid:
   object { automaticNameDelimiter?, cacheGroups?, chunks?, defaultSizeTypes?, enforceSizeThreshold?, fallbackCacheGroup?, filename?, hidePathInfo?, maxAsyncRequests?, maxAsyncSize?, maxInitialRequests?, maxInitialSize?, maxSize?, minChunks?, minRemainingSize?, minSize?, minSizeReduction?, name?, usedExports?}
   -> Options object for splitting chunks into smaller chunks.

Previous version:

  CacheGroups:{
                vendor:{
                    test:/[\\/]node_modules[\\/]/,
                    name:'vendors',
                    chunks:'all'
                }
            }

The solution is to reduce the version or follow the new writing method

New writing:

cacheGroups: {
                commons: {
                  test: /[\\/]node_modules[\\/]/,
                  name: 'vendors',
                  chunks: 'all',
                },
              },
