对于我的CakePHP应用程序，我正在尝试通过composer安装eonasdan/bootstrap-datetimepicker。
但是，与所有其他软件包不同，它及其依赖项安装在components而不是vendor/components中：
$ composer require eonasdan/bootstrap-datetimepicker
Using version dev-master for eonasdan/bootstrap-datetimepicker

顺便说一句，我注意到jQuery和Moment都再次安装（因为它们是bootstrap-datetimepicker的依赖项），虽然我已经安装了这些（出于我的原因）。
为什么会这样？我该如何解决？
