javascript - 不能通过Webpack要求Popper

我正在尝试将JavaScript文件移至Webpack。我对Webpack不太熟悉，因此不确定我是否正确编写了其中的任何代码。我正在尝试加载jquery-ui，popper和bootstrap4。但是，在需要Popper时出现错误。请注意，我将Wepacker gem用于Ruby on Rails。

我在我的environment.js文件中包含了以下代码，以在每个文件中自动包含jQuery。

const { environment } = require('@rails/webpacker')

const webpack = require('webpack')
environment.plugins.append('Provide', new webpack.ProvidePlugin({
  $: 'jquery',
  jQuery: 'jquery'
}))

module.exports = environment

这部分有效。因此，从那里我运行了yarn add jquery-ui。

然后，在我的/pack/application.js文件中加入了require('jquery-ui')。

从我的js文件中，以下代码打印到我的控制台：

$(document).ready(function(){
    if (jQuery.ui) {
      console.log("loaded");
    }
});

之后，我尝试安装并要求使用popper和yarn add popper。

然后从我的document.ready函数内部调用popper，我得到一个错误：

$(document).ready(function(){

    console.log(window.Popper)

});

错误：

这是我的pack / application.js文件

require("@rails/ujs").start()
require("@rails/activestorage").start()

require('jquery-ui')
require('popper')

最佳答案

我只是做了同样的事情，然后才意识到问题出在哪里。 popper是Node中的某种高级浏览器测试库。引导程序依赖于popper.js，这是浏览器的工具提示弹出库。

因此，要解决此问题，您需要：

yarn remove popper
yarn add popper.js
