php - fatal error : Class CI_Session_files_driver contains 1 abstract method

Question

Fatal error: Class CI_Session_files_driver contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (SessionHandlerInterface::open) in C:\xampp\htdocs\cmms2\system\libraries\Session\drivers\Session_files_driver.php on line 49

当我在本地主机 xampp Web 应用程序项目上工作时，此错误不断出现。顺便说一句，我正在使用 codeigniter。您认为出现这种情况的原因是什么？这些是我用 session 完成的唯一代码。

  $this->session->set_userdata($data);
    $autoload['libraries'] = array('database','session');
    $config['sess_driver'] = 'files';
    $config['sess_cookie_name'] = 'ci_session';
    $config['sess_expiration'] = 7200;
    $config['sess_save_path'] = sys_get_temp_dir();
    $config['sess_match_ip'] = FALSE;
    $config['sess_time_to_update'] = 300;
    $config['sess_regenerate_destroy'] = FALSE;

如果不工作，请重新启动 apache 服务器，然后再次下载 CodeIgniter 并用新的替换您的 system/目录。
