十一出门，走的时候断电直接拉了电闸（不是x，回来之后，宝塔面板进不去了！

打开网站，一切正常，都能进去。网站的redis，mysql都是正常的。后台bt命令也正常，只是唯独宝塔面板地址显示——127.0.0.1拒绝了我们的连接请求。。于是群里求助，群友说大概率是端口没开放，于是使用命令netstat -ntlp查看端口，没有8888端口！紧接着就去百度搜解决方法了。

运行bt打开宝塔菜单，查看一下错误日志——22，显示以下错误：

不行啊，这么长的一片，完全看不懂，紧接着使用修复命令——16，显示以下错误：

这个短，看出来是在/www/server/panel/pyenv/lib/python3.7/路径下出了问题。在宝塔论坛 发帖求助 也没人搭理。只好强硬的来尝试修复了——

• 直接重命名/www/server/panel/pyenv/文件夹
• 使用官方安装命令覆盖安装宝塔面板，修复python环境

在安装了108分钟之后，顺利的进入到了后台，这时查看netstat -ntlp，也能看到8888端口了，一切正常了！！

爽啊啊啊啊~~
