【问题描述】：
一段时间以来，我一直在浏览版块和论坛，试图弄清楚为什么我的轮播无法加载/滚动。我读到必须链接到 popper.js 文件，读到关于在引导之前加载 jquery 和 popper，以及很多其他问题。一旦我开始加载 popper.js，我的控制台就不会出现任何错误。谁能在我的 HTML 中看到问题并告诉我为什么轮播不会自动滚动或使用字形图标滚动？当我单击轮播时，它什么也不做，给我任何错误或转到#theCarousel，就像在我加载 popper js 文件之前所做的那样。感谢任何人提供的任何帮助。

【问题讨论】：
-
afaik，popper 适用于 bootstrap 4。你使用的是正确的 bootstrap js 版本吗？你的 CSS 是第 3 版
-
你是对的。我在使用今晚下载的自己的引导 css 文件时遇到问题，不确定它是什么版本。所以我链接到它并修复它。但我只是尝试使用没有 popper 的 v3，你是对的，它不需要它。
