title: Error using lodash.clonedeep in Angular 5
body: <p>First, I have never used lodash.clonedeep before but know JavaScript fairly well.</p>
  
  <p>From my package,json file:
      "lodash.clonedeep": "4.5.0",</p>
  
  <pre><code>import { cloneDeep } from 'lodash.clonedeep';
  
  editStart(): void {
     this.oldData = cloneDeep(this.currentData);
     this.editing = true;
  }
  </code></pre>
  
  <p>Error: ERROR TypeError: lodash_clonedeep_1.cloneDeep is not a function</p>
  
  <p>Help very MUCH appreciated since I'm out of options, have read and tried a lot of options. I have a workaround, using several objects, but want to avoid if possible.</p>
