这个错误的原因是啥啊，还有index.js和layout.html哪个是基本模版啊，首页好像用的是layout,里面的story用的是index.js，，，菜鸟求解答

服务端渲染失败就会启用前端渲染，错误原因是服务端没有window对象，你看看哪里有用到这个，加个判断 前端环境下执行这块代码就行了~

@ZyJoey 多谢，已经找到原因了，服务器渲染失败，原因是regeneratorRuntime is not defined，安装babel-plugin-transform-runtime之后就可以解决了，https://segmentfault.com/a/1190000009065987
