为什么我的节点应用程序没有在 ec2 实例上的 amazon linux 2 AMI 上启动并显示此错误? [英] why my node app don't start on amazon linux 2 AMI on ec2 instance and showing this error?

问题描述

我已将所有文件正确传输到我的 ec2 实例，并且所有节点模块都已使用 package.json 文件成功下载，我的 ec2 实例的操作系统是 Amazon linux 2，但是每当我在终端上运行 npm start 时，我都会得到以下错误.我已经搜索了很多，并在网上关注了许多类似或相同的问题，但仍然无法弄清楚.

I have transferred all my files correctly to my ec2 instance and all the node modules are downloaded successfully with package.json file , the OS of my ec2 instance is Amazon linux 2, but whenever i run npm start on the terminal i get the following error. I have searched this alot and followed many similar or same issues on the web , but still can't figure it out.

终端说:-

[ec2-user@ip-172-31-7-38 backbenchers]$ npm start

> learners-backend@1.0.0 start
> nodemon app.js
