老師是這樣寫的

但是報錯了

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`).

后來看到官網是類似這樣寫的
