【问题描述】：
Here is a link 到提供相同类型信息的包 (nodejs-info)。
如果您想查看存在哪些环境变量，您也可以console.log 他们喜欢：console.log(process.env);
【讨论】：
它与phpinfo() 不完全等价，但是您通常会询问 phpinfo 的任何问题都可以通过process 全局变量来回答。 Rastalamm 的回答涉及到这一点，但不仅仅是process.env。
很像 phpinfo，console.log(process) 会告诉你正在运行的节点版本、加载了哪些内部/原生模块（不同于 NPM 模块）以及process.config 下的各种配置设置。
下面是一个示例，来自我在模拟 Lambda 环境时的 AWS Cloud9 实例：
