为什么 sails.js 忽略 /config/env/production.js 而使用 process.env.PORT 代替？

Question

我在 /config/env/production.js 中将端口设置为 8080，并将环境变量 NODE_ENV 设置为生产。然而，当我扬帆起航时，我只让它在 8000 端口启动。最终我意识到我可以设置端口环境变量并获得正确的结果，但我更愿意使用普通的配置文件。我没有 local.js 配置文件，所以不会覆盖。我做错了什么？

[15:12:50] nodejs @ myserver : /apps/myapi/
$ cat config/env/production.js

module.exports = {

  /***************************************************************************

   * environment (see config/connections.js and config/models.js )           *

  // models: {
  //   connection: 'someMysqlServer'
  // },

  /***************************************************************************

  port: 8080,

  /***************************************************************************

  // log: {
  //   level: "silent"
  // }

};

Answer 1

原来父目录中有一个 .ENV 文件自动设置端口环境变量（即使我取消设置）。我想在这种情况下，sails 在 /config/production.js 上尊重环境变量是有意义的。

为什么 sails.js 忽略 /config/env/production.js 而使用 process.env.PORT 代替？

Why does sails.js ignore /config/env/production.js and use process.env.PORT instead?
