Datepicker 不适用于 bootstrap 4答案

【问题标题】：Datepicker is not working with bootstrap 4Datepicker 不适用于 bootstrap 4
【发布时间】：2020-03-25 18:59:21
【问题描述】：

我想要用户可以选择日期范围的功能。单击第一个文本框时，日期选择器应该打开，用户可以选择开始日期，第二个文本框也可以选择结束日期。

下面的代码，我试过了但是没用，我控制台它会抛出这个Uncaught TypeError: $(...).datepicker is not a function", 错误...

请帮我解决它。任何帮助将不胜感激。
