开发时候快速定位问题

很多时候，同一个git库拉下来的代码，在我的电脑上能运行可是在别人的上面就不行，今天在开发这是为啥呢？这肯定和系统环境有关，而系统环境又涉及比较多一些维度，我们如果一个个比较难免会非常浪费时间，这里给大家介绍一款快速查看各个环境变量值得小工具，先上效果：

    Safari: 13.0.5

这是我的最终效果，那会列出来你电脑上所有和开发相关的各个环境变量的值，这样只要比较两台电脑哪些环境变量不一样，就能快速定位问题了。
安装：

npm install -g envinfo || yarn global add envinfo

之后终端运行 envinfo即可！我一般都会把这个信息保存到git里面，后面出问题之后，可以即时恢复正确时候的环境变量，不至于那一天为了运行一次程序配很久很久的环境。
