突然間,我開始時,我嘗試打開我的下拉菜單中得到錯誤:bootstrap.min.js:6未捕獲的錯誤:引導下拉需要Popper.js
bootstrap.min.js:6 Uncaught Error: Bootstrap dropdown require Popper.js (https://popper.js.org)
at bootstrap.min.js:6
at bootstrap.min.js:6
at bootstrap.min.js:6
我使用標準的引導文件
<script src="https://getbootstrap.com/dist/js/bootstrap.min.js">
bootstrap中有任何改變我必須小心謹慎?
令我加載的文件是繼
<script src="https://code.jquery.com/jquery-1.9.1.js"></script>
<script src="{{ STATIC_URL }}/static/jquery/jquery-1.9.1.js"></script>
<script src="https://code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
