Question

我正在使用feathersjs框架来开发nodejs应用程序，我正在尝试在pm2中实现它并且它无法正常工作。

这是我的应用程序文件夹结构：

我正在按照以下方式运行

$ cd src
$ pm2 start app.js

我收到了以下错误：

Answer 1

app.js不是feathersjs样板中的根文件。

它应该是index.js

所以只需使用pm2 start src/

Answer 2

当找不到适合您环境的配置文件（config/default.json，config/production.json等）时，例如在Dockerfile中，如果配置文件未正确复制，也会出现此错误。

如何在pm2中部署feathersjs应用程序？
