【问题描述】:
无法读取未定义的属性“原型”。 /node_modules/express/lib/response.js:42
当我运行我的 react 应用程序和一个 express 后端时,我收到了这个错误。应用程序一直运行良好,直到错误突然出现。
39 | * @public
40 | */
41 |
> 42 | var res = Object.create(http.ServerResponse.prototype)

这是我在控制台中得到的:

【问题讨论】:
-
我假设你已经完成了所有基本的事情,比如重启、清除 node_modules 和重新安装等。BookItem.js 中的第 24 行是什么?
-
它是一个渲染书籍项目的组件。它是我创建的第一批组件之一,并且一直在工作。
