Question

这是我第一次使用 React + ExpressJs + Typescript 我在 node_modules 中收到以下错误，我不确定它来自哪里。我已经为 node 和 expressjs 安装了类型包。

TypeError: Cannot read property 'prototype' of undefined
(anonymous function)
Z:/Project/sandbox-app/node_modules/express/lib/response.js:42
  39 |  * @public
  40 |  */
  41 | 
> 42 | var res = Object.create(http.ServerResponse.prototype)
  43 | 
  44 | /**
  45 |  * Module exports.

这是我设置 Express 服务器的代码

import express from "express"
import bodyParser from "body-parser"

const app = express()
const port = 3000

app.use(bodyParser.json())
app.use(
  bodyParser.urlencoded({
    extended: true,
  })
)

app.get("/", (request, response) => {
  response.json({ info: "Node.js, Express, and Postgres API" })
})
app.listen(port, () => {
  console.log(`App running on port ${port}.`)
})

完整的堆栈跟踪
