Fluidbox和Webpack有问题吗？ （0，_jquery2.default）（...）。fluidbox

Question

我的App.js

import $ from 'jquery';
import fluidbox from 'fluidbox';
import FluidBoxWpGallery from './modules/FluidBoxWpGallery';
var fluidBoxWpGallery = new FluidBoxWpGallery();

我的FluidBoxWpGallery（）：

import $ from 'jquery';
class FluidBoxWpGallery {
    constructor() {
    this.els = $(".gallery a");
    this.initFluidGallery();
}

initFluidGallery() {
    this.els.each(function() {
      $(this).attr('data-fluidbox','');
    });
    if($('[data-fluidbox]').length>0){
      $('[data-fluidbox]').fluidbox();
     }   
  }
}
export default FluidBoxWpGallery;

一切正常...元素获得attr数据流框，但错误在第15/16行。我认为在webpack中

这是控制台中的输出：

App.js?ver=4.9.8:10051 Uncaught TypeError: (0 , _jquery2.default) . 
(...).fluidbox is not a function
at FluidBoxWpGallery.initFluidGallery (App.js?ver=4.9.8:10051)
