Question

我在将 Node/Postgres 应用程序部署到 Heroku 时遇到问题。当我运行部署脚本时，构建完成，但在打开数据库连接后，会因缺少模块而引发错误。我的 Procfile 包含 web: node main.js 和我在 package.json 中的启动脚本状态 "start": "node main"。

下面我附上了 heroku logs 的副本和 main.js 中的代码，它位于根目录中。

main.js

const {db} = require('./server/db')
const app = require('./server')
const PORT = process.env.PORT || 5409

db.sync()
  .then(() => {
    console.log('db synced')
    app.listen(PORT, (e) => {
      if (e) throw (e)
      console.log(`Listening on port ${PORT}`)
    })
})

有什么想法吗？
