[root@iZj5y097t26vcxipo7iopfZ /]# btpip install cryptography==40.0.2
DEPRECATION: Python 2.7 reach ...

您好，这个是当前的服务器中的Python环境太低了；您那边先做个快照，然后依次执行下面命令
1、将当前Python环境做个备份的操作

1. mv /www/server/panel/pyenv/ /www/backup/pyenv_backup
   

复制代码

2、重新执行覆盖安装命令，会重新下载新的Python环境

1. if [ -f /usr/bin/curl ];then curl -sSO https://download.bt.cn/install/install_panel.sh;else wget -O install_panel.sh https://download.bt.cn/install/install_panel.sh;fi;bash install_panel.sh ssl251104

复制代码

如果还是这个问题，那么请继续留言

您好，这个问题是缺少了cryptography 这个依赖导致的；您到服务器SSH终端里执行

1. btpip install cryptography==40.0.2

复制代码

然后重启面板

1. bt restart
   

复制代码

重新打开面板的登录界面（建议使用浏览器无痕模式）看下是否还是会出现这个情况。
