Javascript 无法读取文件imagick异常

我正在尝试将PDF转换为图像，但它显示“无法读取文件imagick异常”错误。我已安装ghost脚本和imagick。这两个都是用Apache$path向我展示的。但是这个问题还是要来了，请帮帮我

多谢各位

我的代码是这样的

if(!empty($society_member_details['user_society_member_id_proof'])){
$id_proof_array = explode(".",$society_member_details['user_society_member_id_proof']);
                if (end($id_proof_array) == "pdf"){
                    $image = new Imagick();
                    $image->pingImage(base_url().'/uploads/users/'.$this->session->user_id.'/society_forms/id_proof/'.$society_member_details['user_society_member_id_proof']);
                    $page_count = $image->getNumberImages();
                    
                    for ($i=0; $i < $page_count; $i++){
                        $img = new imagick(APPPATH.'../uploads/users/'.$this->session->user_id.'/society_forms/id_proof/'.$society_member_details['user_society_member_id_proof']);

                        //set new format
                        $img->setImageFormat('jpg');

                        $image_name = str_replace(".pdf","",$society_member_details['user_society_member_id_proof']).$i;
                        //save image file
                        $img->writeImage(APPPATH.'../uploads/users/'.$this->session->user_id.'/society_forms/id_proof/'.$image_name.".jpg");
                        chmod(APPPATH.'../uploads/users/'.$this->session->user_id.'/society_forms/id_proof/'.$image_name.".jpg", 0777);
                        $id_card_data .= '<img style="max-width:600px;max-height:600px;" src="'.base_url().'uploads/users/'.$this->session->user_id.'/society_forms/id_proof/'.$image_name.'.jpg" /><br/>';
                    }
                }

 

$image->pingImage(base_url().'/uploads/users/'.$this->session->user_id.'/society_forms/id_proof/'.$society_member_details['user_society_member_id_proof']);
