Debugkit can not be found

It can not be represented correctly because it is translated into English from Japanese by using the Google translation .

I’m using CakePHP 3.3.3 in Lampp.
When you create a CakePHP in the folders under DocumentRoot will find debug_kit/js/toolbar.js , but I can not find that the DocumentRoot to webroot.
You will find that it is “bin/cake server”.

Configuration:
Normal operation
Apache
DocumentRoot /home/user/htdocs/
CakePHP Folder
/home/user/htdocs/hoge/(cakephp root)
URL
http://server/hoge/

Abnormal action
Apache
DocumentRoot /home/user/htdocs/webroot/
CakePHP Folder
/home/user/htdocs/(cakephp root)
URL
http://server/

I think that route of the problem, but how do I?
