php将权限写入session,php 一直报session写入失败

Warning: session_write_close(): Failed to write session data using user defined save handler. (session.save_path: tcp://127.0.0.1:6379) in /var/www/html/php/libs/util/Session.php on line 43

问题描述

我的代码写入session 的时候一直报这个问题， 环境是windows10 ubuntu 子系统，session 写入的位置是 memcache 6379 端口，扩展都开启了，有大神能解答一下这是什么问题吗？

问题出现的环境背景及自己尝试过哪些方法

class Session {

// single ton

private static $session_handler_;

public static function Init() {

self::$session_handler_ = new Session();

你期待的结果是什么？实际看到的错误信息又是什么？
