react-redux-starter-kit npm run dev 崩溃

Question

我是 React/Redux 的新手，我正在使用 react-redux-starter-kit 样板来深入研究它。 npm run dev 工作正常，但现在由于此错误而崩溃：

express-react-redux-starter@1.0.0 dev /Users/unomas/Documents/web/suited-template webpack-dev-server --config ./webpack/webpack-dev.config.js --watch --colors

events.js:141
      throw er; // Unhandled 'error' event
      ^

不确定是否有人熟悉此样板或错误。请让我知道任何解决方法。谢谢

Answer 1

您可能已经在 localhost:3000 运行了另一台服务器。尝试在浏览器中点击它来查看。

Answer 2

如果您厌倦了处理 webpack 配置，请尝试Chalet Starter App。 它应用了create-react-app 之类的命令来引导您的应用程序，并且文件夹结构基于react-redux-starter-kit。请参阅Quick Overview 了解更多详情。如果您还有其他问题，欢迎提出问题。
