I've encountered the same problem.
As i understood, CLI build uses ES5 and "export" keyword was added only in ES6, so example in README seems invalid.
My solution was to do it "commonjs" way, and rewrite example with module.exports.

So example in README would look like this:

module.exports = ({ config }) => {
  return {
    ...config,
    module: {
      rules: [
        { ... },
        ...config.module.rules,
      ],
    },
  };
};
