Я хочу запустить свой проект NodeJS на heroku, но это не работает, пока мой проект работает нормально локально.

Когда я ввожу «heroku logs —tail», чтобы увидеть ошибки, я вижу :

 2020-08-18T10:39:44.396002 00:00 app[web.1]: const express = require('express')
2020-08-18T10:39:44.396003 00:00 app[web.1]: ^

2020-08-18T10:39:44.396004 00:00 app[web.1]: ReferenceError: require is not defined
  

Это мой «index.js » :

 const express = require('express')
if (process.env.NODE_ENV === 'dev') require('dotenv').config()

const routerIdeas = require('./routes/ideas.js')

const PORT = process.env.PORT || 5000
const app = express()

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

app.use('/api', routerIdeas)

app.listen(PORT, () => {
    console.log(`Server is running on port : ${PORT}`)
})
  

Это полные «журналы heroku —tail» :

Я попытался запустить тестовый проект, представленный в руководстве Heroku starter, и проблем с «требовать» нет, поэтому я не понимаю.

Заранее благодарю всех, кто может мне помочь

У меня была такая же проблема, и то, что я сделал, было в package.json файле, который я удалил type:module , и это сработало.

Я удалил файлы ‘.git’ и ‘Procfile’. Я также удаляю репозиторий на Heroku и создаю новый. Затем я снова запускаю процедуру, чтобы связать мой проект с новым репозиторием. Затем я запустил проект, и теперь ошибок больше нет.

Я не понимаю, почему, но это работает сейчас.
