[Error] when update to 2.0.0, Error while loading config - Unexpected token 'export'

Internal server error: .....\babel.config.js: Error while loading config - Unexpected token 'export'

find the solution ： just turn the babel export default to module.exports,
but when the version is 1.9.3 the babel.config.js is able to use export default
