Problem with get_stylesheet_directory using child theme

function add_required_scripts() {
   // register your script location and dependencies
   wp_register_script('customscripts', '/get_stylesheet_directory() . /js/bootstrap.min.js', array('jquery'));
   wp_register_script('flexslider',  '/get_stylesheet_directory() . /jquery.flexslider-min.js', array('jquery'), '2.1');
   // enqueue the script
   wp_enqueue_script('customscripts');
   wp_enqueue_script('flexslider');
}
add_action('wp_enqueue_scripts', 'add_required_scripts');

Pretty much the same for the stylesheets just using wp_enque_style()

For the sake of getting things done I currently replaced the calls to get_stylesheet_directory() with the actual path, ie: http://localhost/clients/myclient/js/flexslider.js which loads the scripts and has allowed me to keep working but obviously this is not the best solution.

thanks

Sorry, that was actually a typo on my part here, Like I said I am currently using the full path and replaced it so you could see my non working code. The actual code does not have those characters.

Code is this:

function add_required_scripts() {
   // register your script location and dependencies
   wp_register_script('bootstrap', get_stylesheet_directory() . '/wp-content/themes/twentyfourteen-child/js/bootstrap.min.js', array('jquery'));
   wp_register_script('flexslider',  '/wp-content/themes/twentyfourteen-child/jquery.flexslider-min.js', array('jquery'), '2.1');
   // enqueue the script
   wp_enqueue_script('bootstrap');
   wp_enqueue_script('flexslider');
}
add_action('wp_enqueue_scripts', 'add_required_scripts');

Still returning the broken file path of:

http://localhost/clients/buysellmyhomelaC:xampphtdocsclientsmyclient/wp-content/themes/twentyfourteen-child/wp-content/themes/twentyfourteen-child/js/bootstrap.min.js?ver=3.8.2
