4-2 11:25秒处 babel的配置我按照老师写的报错

老师是这样写的

但是报错了

Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.

 - configuration.module has an unknown property 'loaders'. These properties are valid:

   object { exprContextCritical?, exprContextRecursive?, exprContextRegExp?, exprContextRequest?, noParse?, rules?, defaultRules?, unknownContextCritical?, unknownContextRecursive?, unknownContextRegExp?, unknownContextRequest?, unsafeCache?, wrappedContextCritical?, wrappedContextRecursive?, wrappedContextRegExp?, strictExportPresence?, strictThisContextOnImports? }

   -> Options affecting the normal modules (`NormalModuleFactory`).

后来看到官网是类似这样写的
