Question

我过去曾经使用过express，但是第一次尝试打字稿。我不确定此错误是否与打字稿有关，但我无法想到可能导致此问题的任何其他原因。我也在使用WSL，但是到目前为止，在节点上我从未发生过任何故障-尽管我没有使用很长时间。

这是导致异常的代码：

import { createSecureServer } from 'http2'
import { readFileSync } from 'fs'
import * as express from 'express'

const key = readFileSync('/etc/ssl/private/selfsigned.key')
const cert = readFileSync('/etc/ssl/certs/selfsigned.crt')


const server = createSecureServer({ key, cert }, express)

server.listen(3000, 'localhost', () => {
    console.log('Server is up and running!')
})

这是例外：

TypeError: argument fn must be a function

    at c (/mnt/c/Users/caleb/Code/stats-backend/dist/app.js:20255:3584)

package.json：

{
  "devDependencies": {
    "@types/express": "4.16.1",
    "@types/node": "^12.0.4",
    "fuse-box": "^3.7.1",
    "typescript": "^3.5.1",
    "uglify-es": "^3.3.9"
  },
  "dependencies": {
    "express": "4.16.1"
  }
}

我做错了什么导致我收到此错误？

运行express（）时发生TypeError
