Angular 2/Ionic 2 TypeError : zxcvbn_1.默认不是函数

使用Jasmine和Karma进行测试，
我正在使用zxcvbn库进行一些密码强度计算。
当我尝试通过调用下面的updateScore()函数在其上运行规范时，此操作将失败。

private updateScore(): void {
    const analysis = zxcvbn(this.password)
    this.score = analysis.score;
    this.comment = analysis.feedback.warning || analysis.feedback.suggestions[0];
  }

在导入中，我正在做import zxcvbn from 'zxcvbn';
这在应用程序中有效，甚至在我构建和仿真时也是如此，但是在规范中，它给了我这个错误:

最佳答案

我在使用时遇到了这个问题
import linkifyStr from 'linkifyjs/string';
代替
import * as linkifyStr from 'linkifyjs/string';
