我至少应该得到灰色导航栏，但我在底部收到红色符号错误“无法加载样式表”。即使尝试一次删除一个 css 但没有任何帮助。
我还在控制台中收到此错误“ReferenceError:Popper 未定义”。 即使我没有在 sublime 中得到与 Bootstrap 类相关的自动建议。

最佳答案
来自Bootstrap网站
Many of our components require the use of JavaScript to function. Specifically, they require jQuery, Popper.js, and our own JavaScript plugins. Place the following s near the end of your pages, right before the closing tag, to enable them. jQuery must come first, then Popper.js, and then our JavaScript plugins.
<script src="path/jquery"></script>
<script src="path/popper"></script>
<script src="path/bootstrap"></script>
您似乎需要在应用程序中添加 popper.js。请注意上述代码片段中的文件顺序
