在项目中使用lint-stafed进行代码格式化和检查时，报错:

D:\Projects\my-app\node_modules\any-observable\register.js:29
                throw new Error('Cannot find any-observable implementation nor' +
                ^

Error: Cannot find any-observable implementation nor global.Observable. You must install polyfill or call require("any-observable/register") with your preferred implementation, e.g. require("any-observable/register")('rxjs') on application load prior to any require("any-observable").

网上有如下几种解决方案：

1. 删除node_modules和package-lock.json，重新执行 npm install;
2. 安装依赖 npm install rxjs-compat;
3. 将 list-staged 模块更新至最新版 ;

但是三种方式尝试后，我的报错还是没有解决，遂取寻找源头查看原代码：

any-observable/register.js.png

很明显，是变量 imp1 不存在时报错，根据源码尝试安装插件：执行 npm install rxjs 后，报错消失，代码正常运行。
