node-red require('cryptojs') cryptojs.HmacSHA256 undefined

各位老板请教一下，我在doeker中run了node-red，使用cryptojs HmacSHA256加密方法undefined。我使用了以下两种方式，----------------------
方法一：
settings.js文件
    functionGlobalContext: {
        require:require
    },

function使用
var CryptoJS = require("crypto-js");
var ts = Math.floor(Date.now() / 1000)
var source = "lennyguotest"
var signStr = "x-timestamp: " + ts + "\nx-source: " + source
var auth = CryptoJS.HmacSHA256(signStr, appKey).toString()

报错
"TypeError: Cannot read property 'HmacSHA256' of undefined"
--------------------
方法二：
修改settings.js文件
    functionGlobalContext: {
        cryptojs:require('crypto-js')
    },

function使用：
var CryptoJS = context.global.cryptojs;
var ts = Math.floor(Date.now() / 1000)
var source = "lennyguotest"
var signStr = "x-timestamp: " + ts + "\nx-source: " + source
var auth = CryptoJS.HmacSHA256(signStr, appKey).toString()


报错与上面一样
--------------------
有老板遇到求解答一下？
