小编Dev*_*dog的帖子

我正在 Mac 上重新整理文档，不小心损坏了我正在构建的应用程序。我注意到 package.json 已与 router.js 一起删除。我将这两个文件以及 package.json 中的 koa 依赖项添加回来进行测试。

控制台错误

索引.JS

const Koa = require('koa');
const app = new Koa();

这是 index.js 中的“koa” require 尝试获取模块的地方。 模块路径不正确

module "/Users/devunderdog/Library/Caches/typescript/3.9/node_modules/@types/koa/index"

包.JSON

   {
      "name": "fantasy_sports_manager_server",
      "version": "1.0.0", …
