Angular Lodash forEach不是函数-更新后

我一直在Angular CLI 2.2.3中使用Lodash，没有任何问题。但是，在将Angular CLI更新到2.3.1之后，我遇到了一些问题。第一个错误是错误：在angular cli？中找不到模块“lodash”？。 我通过以下方式解决了此问题：

npm install lodash --save
npm install @types/lodash --save-dev

并添加到angular-cli.json

"scripts": ["../node_modules/lodash/lodash.js”],

这使得MyAngular 2项目可以无错误地编译。但是，当我转到使用lodash foreach的组件时，会出现以下错误：

我正在将lodash函数导入到我的组件中，如下所示：

import * as _ from "lodash"; 

下面是我在代码中使用foreach的方式：

printYArr(): void {
    this.totalFlex  = [];
    // Get y
    let yArr: number[] = [];
    // Get array of y
    _.forEach(this.elements, function(obj: FormElement) {
      if (yArr.indexOf(obj.y) < 0) {
        yArr.push(obj.y);
      }
    });
    console.log('yarr',yArr);
  }

还有谁遇到这个问题，能帮我解决吗？提前感谢

您是否尝试过使用u.each而不是u.forEach？您是否会遇到相同类型的错误？顺便说一句，我从来没有过这个问题。这是暗中刺伤；这不应该奏效，但值得一试。
