错误 [ERR_REQUIRE_ESM]：必须使用导入来加载 ES 模块：尝试部署 Node.js 时出错

如何解决错误 [ERR_REQUIRE_ESM]：必须使用导入来加载 ES 模块：尝试部署 Node.js 时出错

我正在尝试在数字海洋上部署我的 MERN 堆栈应用程序， 前端工作正常， 我的后端 server.js 有问题，我在 package.json 中使用了“type”：“module”，

出现此错误

  code: 'ERR_REQUIRE_ESM'
7|server   | }
7|server   | Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /var/www/html/backend/server.js
7|server   |     at Object.Module._extensions..js (internal/modules/cjs/loader.js:1015:13)

7|server   |     at internal/main/run_main_module.js:17:47 {
7|server   |   code: 'ERR_REQUIRE_ESM'
7|server   | }

这是我的 packacge.json 的样子

}

这是我的 server.js

import path from 'path'
import express from 'express'
import dotenv from 'dotenv'
import colors from 'colors'
import { notFound,errorHandler } from './middleware/errorMiddlleware.js'
import connectDB from './config/db.js'
import eventRouter from './routes/eventsRoute.js'
import blogRouter from './routes/blogRoute.js'
import userRouter from './routes/userRoutes.js'
import uploadRouter from './routes/uploadRoutes.js'

dotenv.config()
connectDB()
const app = express()
app.use(express.json())


app.use('/api/events',eventRouter)
app.use('/api/blogs',blogRouter)
app.use('/api/users',userRouter)
app.use('/api/uploads',uploadRouter)


const __dirname = path.resolve()
app.use('/uploads',express.static(path.join(__dirname,'/uploads')))

if(process.env.NODE_ENV === 'production'){
    
  app.use(express.static(path.join(__dirname,'/frontend/build')))  

  app.get('*',(req,res) => {
      res.sendFile(path.resolve(__dirname,'frontend','build','index.html'))
  })
} else {
   app.get('/',res) => {
     res.send('App Is Running...')
   })
}


app.use(notFound)
app.use(errorHandler)

const PORT = process.env.PORT || 5000

app.use((req,res,next) => {
  res.header("Access-Control-Allow-Origin","*");
  res.header("Access-Control-Allow-Headers","Origin,X-Requested-With,Content-Type,Accept");
  next();
});

app.listen(5000,() => {
    console.log(`Server Is Running In ${process.env.NODE_ENV} Mode  On Port ${PORT}`.yellow.bold)
})

有人可以帮忙吗？有什么想法吗？

这里是我的前端运行正常，但如果你去 http://104.236.106.171/events 它会导致错误，:((

http://104.236.106.171/

在本地它工作正常
