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.
当使用节点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，似乎也会发生这种情况。
Calling process.env from the command line seems to work, though:
但是，从命令行调用process.env似乎有效：
$ node
> process.env
{ MANPATH: '/opt/local/share/man:',
TERM_PROGRAM: 'Apple_Terminal',
...
Any idea what could be going wrong?
什么可能出错？

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.
我想到了。 process是一个对象（https://nodejs.org/api/process.html），但是我定义了我自己的函数（也称为process）来覆盖它。更改我的功能名称修复了问题。
