Unresolved variable enc, anything...

[oustr]

I used yarn add crypto-js to install and it's the latest version 4.1.1. However, no matter it's import CryptoJS from "crypto-js" or const CryptoJS = require("crypto-js"), I just couldn't use CryptoJS.enc, CryptoJS.AES and anything else, and WebStorm always tells me something like unresolved variable enc.


I don't understand why I meet this problem since everything is right with my other imports or requires.
