我使用email.js从我的服务器发送电子邮件，Node.js和Express。Email.js有一个npm包，所以我使用const emailjs = require("emailjs")导入它。但是，我收到一个错误：

Instead change the require of email.js in Mycomputer\index.js to a dynamic import() which is available in all CommonJS modules.
   at Object.<anonymous> (Mycomputer\index.js:4:17) {
 code: 'ERR_REQUIRE_ESM'
}

什么是dynamic import？如何在我的项目中使用它？这段代码在使用<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/@emailjs/browser@3/dist/email.min.js"></script>的客户端上运行良好
下面是我的代码：

const { response } = require("express")
const express = require("express")
const app = express()
const emailjs = require("emailjs")

const port = 3000
app.listen(port, () => {
    console.log(`Listening at port ${port}`)
})

app.use(express.static("public"))
app.use(express.json({limit: "1mb"}))

app.post("/email", (request, response) => {

    (function () {
        // https://dashboard.emailjs.com/admin/account
        emailjs.init("My top secret API key")
    })();

    const sendContactData = (parmas) => {
        const tempParmas = {
            from_name: request.body.from_name,
            reply_to: request.body.reply_to,
            subject: request.body.from_namerequest.body.subject,
            message: request.body.message,
        }

        emailjs.send("My top secret service ID", "My top secret template", tempParmas).then((res) => {
            console.log(res)
            response.send("Success!")
        })

    }
    response.send("Success!")
    console.log(request.body)
})
