npm run build 時のビルドエラー

npm run build の実行時のビルドエラーが出ます。
http://c16e.com/1510161700/　の通り作っています。下準備: webpackでビルドを試す　のところを行なっています。package.jsonに

{
  "name": "react-like-button",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "build": "rm -rf dist/*.js && webpack",
    "watch": "rm -rf dist/*.js && webpack -w"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "babel-loader": "^7.1.4",
    "webpack": "^4.1.1"
  }
}

と書いて、npm run buildを実行すると、

> react-like-button@1.0.0 build /Users/xxx/react-like-button
> rm -rf dist/*.js && webpack

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`).

とエラーが出ました。バージョンの違いでこのようなエラーが出てしまう、とhttps://qiita.com/ryusaka/items/8778e3b2afcffc8e7ca6　の記事にあったのですが、この場合はどこがバージョンの違いのエラーを起こしているのかわからなかったです。webpack.config.jsには

module.exports = {
  entry: __dirname + "/src/main.js",
  output: {
    path: __dirname + "/dist",
    filename: "like-button.js"
  },
  module: {
    loaders: [
      {test: /\.js$/, loader: "babel-loader?stage=0"}
    ]
  }
};

と書きました。修正箇所をご指摘ください。
