javascript - 如何解决这个 java-script 文件的引用错误？

Question

我通过 server.js 将名称作为元素传递给 index.ejs，但由于名称未定义而出现错误。

当我没有呈现任何名称但使用名称时，我可以打印 hi，它会给出错误。

我是编码新手。

const express=require('express')
const app=express()

app.set('view engine','ejs')


app.get('/',(req,res)=>{
    res.render('index.ejs',{ name: 'V'})
})

app.listen(3000)

<h1>HI <%= name%> </h1>

ReferenceError: C:\Users\van\Documents\Testing Node JS\views\index.ejs:1
 >> 1| <h1>HI <%= name%> </h1>

name is not defined
