\'supports\'              => array( \'title\', \'editor\', \'excerpt\', \'thumbnail\', ),

请在register\\u post\\u type之后将其用于自定义post type

add_theme_support( \'post-thumbnails\', array( \'post\', \'movie\' ) ); // 帖子和电影

或

$args = array(
        \'labels\'             => \'Basics\',
        \'public\'             => true,
