Bootstrap,即使在导入bootstrap bundle之后,Popper也会丢失

Question

我正在努力使用bootstrap4.我已导入bootstrap.bundle.js已包含的内容popper.js.

但无论如何我得到以下错误:

Uncaught ReferenceError: Popper is not defined

包括结构

<script type="text/javascript" src=".../js/jquery-3.2.1.min.js"></script>
<script type="text/javascript" src=".../js/bootstrap.bundle.min.js"></script>
<script type="text/javascript" src=".../js/bootstrap.min.js"></script>

Answer 1

bootstrap.bundle.js或bootstrap.bundle.min.js包含Bootstrap + Popper.js所以你只需要包含jQuery和Bootstrap Bundle,一切都完成了
