【问题描述】：

我的服务器在本地运行良好，但是当我在部署到 amazon ec2 后启动服务器时，它会引发以下错误：这个解决方案对我来说不够用https://github.com/fbsamples/messenger-platform-samples/issues/43

node dist/app.js

节点分布/app.js

怀疑没有加载process.env，我什至尝试硬编码以下值，但结果是一样的。

const VALIDATION_TOKEN = '3f92bb17caf0e11f5632920a402e1687'

【问题讨论】：

nodejs EADDRINUSE error的可能重复
lsof -i :3979 -> kill -1 pid_shown_by_previous_command 并再次运行您的应用程序。

【解决方案1】：

问题在于服务器已经在运行，错误：监听 EADDRINUSE :::3979

在部署脚本中添加pkill -f node 在启动节点服务器之前解决了问题
