process.env

https://nodejs.org/dist/latest-v6.x/docs/api/process.html#process_process_env

{
  TERM: 'xterm-256color',
  SHELL: '/usr/local/bin/bash',
  USER: 'maciej',
  PATH: '~/.bin/:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin',
  PWD: '/Users/maciej',
  EDITOR: 'vim',
  SHLVL: '1',
  HOME: '/Users/maciej',
  LOGNAME: 'maciej',
  _: '/usr/local/bin/node'
}

可以修改此对象，但这些修改不会反映在Node.js进程之外。换句话说，以下示例将不起作用：


$ node -e 'process.env.foo = "bar"' && echo $foo

以下将会：

process.env.foo = 'bar';
console.log(process.env.foo);

在process.env上分配属性会将值隐式转换为字符串。
