在Node app中未定义process.env [英] process.env undefined in Node app

问题描述

使用node server.js运行我的Node应用程序时，process.env返回undefined，因此我无法访问任何环境变量.当我尝试将我的应用程序部署到 Duostack 时，也会出现这种情况.

When running my Node app with node server.js, process.env returns undefined, so I'm unable to access any environment variables. This also seems to occur when I attempt to deploy my app to Duostack.

从命令行调用process.env似乎可以，但是:

Calling process.env from the command line seems to work, though:

$ node
> process.env
{ MANPATH: '/opt/local/share/man:',
  TERM_PROGRAM: 'Apple_Terminal',
...

有什么想法会出问题吗?

Any idea what could be going wrong?

推荐答案

我知道了. process是一个对象( https://nodejs.org/api/process.html ) ，但是我定义了自己的函数(也称为process)来覆盖它.更改我的函数的名称可以解决此问题.

I figured it out. process is an object (https://nodejs.org/api/process.html), but I'd defined my own function (also called process) that overwrote it. Changing the name of my function fixed the problem.
