我似乎无法让particles.js 工作——我到底做错了什么？任何见解将不胜感激，我无法确定错误是否是由于外部依赖造成的...

Problem solved--I needed to make a separate javascript file called app.js and put the JSON in that as a JS function (see how they did their demo and fiddle around with it till you can make it do what you want)
问题解决了——我需要制作一个名为 app.js 的单独 javascript 文件，并将 JSON 作为 JS 函数放入其中（看看他们是如何做他们的演示并摆弄它直到你可以让它做你想做的）
