下拉菜单popper.js
[英]Dropdown menu popper.js
问题描述
I'm trying to make a dropdown menu but I get this error: 
我正在尝试制作下拉菜单，但出现此错误：
"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"
I found some questions about it here but none of them worked for me. 我在这里发现了一些问题，但没有一个对我有用。 How do I import this popper.js? 如何导入此popper.js？

I just found a way to import with script tag...it was all this time in bootstrap documentation. 我刚刚找到了一种使用脚本标签导入的方法...引导程序文档中一直都在这。 But, there's one more problem: The code is free of erros but my dropdown button isn't working. 但是，还有一个问题：代码没有错误，但是我的下拉按钮不起作用。 I tried every single dropdown in bootstrap documentation, I ctrl+c - ctrl-v all of them and none of them are working, I click on the button and nothing happens :( 我尝试了引导文档中的每个下拉列表，我都按ctrl + c-ctrl-v进行了操作，但都不起作用，我单击了按钮，没有任何反应:(
