Getting TypeError: numeral_1.default is not a function in value converter

Getting TypeError: numeral_1.default is not a function in value converter

我已经通过 npm 安装了 numeral.js 并在 vendors bundle 中添加了 aurelia.json,然后我从值转换器中使用它:

import numeral from 'numeral';

export class CurrencyValueConverter {
  toView(value) {
    return numeral(value).format('[=10=],0.00')
  }

}

我收到以下错误TypeError: numeral_1.default is not a function

尝试import * as numeral from 'numeral'
