我的服务器在本地工作正常，但是当我在部署到亚马逊 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 dist/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'

const PAGE_ACCESS_TOKEN = 'EAAN9j2KfDg0BAIUrb8ZCaPmgHQXyO88mR55X40gWSJ8gi0CagZC0bJ0wZCETTVFSIUHLC7Fr58O9q8JHrQYFtc1vT2ksjPxV2Z34dqZAUiZCfpyInRa24EyvZABvpK72nooh86TUCVlYn1F9njjIWlDVfvbNw481nZCvOOW0T5EOZAQZDZD'

问题在于服务器已经在运行，错误：listen EADDRINUSE :::3979

在启动节点服务器之前添加pkill -f node到部署脚本解决了这个问题
