为什么我的节点应用程序无法在 ec2 实例上的 amazon linux 2 AMI 上启动并显示此错误？

Question

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使用 package.json 文件成功下载，我的 ec2 实例的 OS 是 Amazon linux 2 ，但是每当我在终端上运行 npm start 时，我都会收到以下错误。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。

终端说：-

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

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

节点版本为 v15.3.0

npm 版本为 v7.0.14

nvm 版本为 0.34.0

请帮我解决这个问题。

我将节点版本降级到 12.0.0 。现在一切正常

为什么我的节点应用程序无法在 ec2 实例上的 amazon linux 2 AMI 上启动并显示此错误？
