Question

我无法使用以下指南安装reactJS： https://www.tutorialspoint.com/reactjs/reactjs_environment_setup.htm

我正在使用： npm 4.2.0 节点7.10.0 红帽企业Linux服务器版本7.2（Maipo）

这是我得到的错误：

[root@webdev2 reactJSApp]# npm start

> test@1.0.0 start /opt/swtapps/reactJSApp
> webpack-dev-server --hot

✖ ｢wds｣: 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`).

有什么建议吗？

该教程已过时。 Webpack 4中的加载程序定义为：

module: {
  rules: [
    {
      test: /\.jsx?$/,
      // options for the loader
    },
  ],
}

对于此类问题，我建议阅读documentation of webpack。
