TypeError: Cannot read property 'case sensitive routing' of undefined

Question

使用 node.js nodemon、express 和 lib。

OS: Windows 10 主页 x64 Node.JS版本：Lts

我想完成的事情：ExpressJS 端口运行。出了什么问题：一个内部文件，但大多数时候它是我的一个代码文件出错（我还不知道）

控制台错误：

此错误表明 this.settings 未定义。根据此处提供的少量信息，假设 this.settings 是一个对象，并且抛出此 TypeError 因为您无法在 [=13= 上“查找”名称为 'case sensitive routing' 的键].确保 this.settings 是一个在第 355 行之前具有键 'case sensitive routing' 的对象。
