【问题描述】：
我第一次尝试使用 webpack 时遇到了困难。
我在浏览器控制台中收到以下错误。
ERROR TypeError: $(...).sparkline is not a function

我已经包含了 jquery-sparkline，但我仍然收到该错误。我可以在 vendor.js 中看到迷你图代码，但它似乎没有任何区别。
我还查看了供应商清单文件，其中包含此文件，但没有提及迷你图。
"./node_modules/jquery-sparkline/jquery.sparkline.js":{
"id":101,
"meta":{
}
}
我也不明白为什么我必须将 ProvidePlugin 放在下面的两个文件中。当然一次就足够了，但是当它只在供应商文件中时，我得到浏览器错误，说它找不到 $。
new webpack.ProvidePlugin({ $: 'jquery', jQuery: 'jquery' })
任何帮助将不胜感激！
谢谢
