您好，这个可能是面板环境错误导致的，您执行下面的命令手动修复一下面板环境，下面的命令不要在面板的终端中执行
备份当前面板环境：

1. mv /www/server/panel/pyenv /www/server/panel/pyenv.bak

复制代码

执行修复面板环境命令：

1. curl http://download.bt.cn/install/update_panel.sh|bash

复制代码

[root@localhost ~]# mv /www/server/panel/pyenv /www/server/panel/pyenv.bak
mv: cannot stat ‘/www/server/panel/pyenv’: No such file or directory

执行第一个命令提示这个错误

还是不行
