用react做的后台管理项目,更换路由之后出现了这个警告,有人遇到过吗?

Question

Warning: The <HeadTable /> component appears to be a function component that returns a class instance. Change HeadTable to a class that extends React.Component instead. If you can't use a class try assigning the prototype on the function as a workaround. HeadTable.prototype = React.Component.prototype. Don't use an arrow function since it cannot be called with new by React.

Answer 1

提示说的不要太清楚；你的代码写的不符合 react 的官方推荐，所以给你警告

Answer 2

我好想解决了，只有在开发环境下才有，发布后就没有这个问题了，如果要解决开发环境下的问题，应该是热更新时导致的。我们在resolve的alias里加入了'react-dom': '@hot-loader/react-dom'
