重启宝塔面板后提示-ModuleNotFoundError: No module named 'geventwebsocket'

背景：

因服务器部署了flask项目，安装了python3，故重启宝塔面板报错

------------------------------------------------------
Error: BT-Panel service startup failed.

解决办法：

1、python3安装geventwebsocket

我不想拆卸python3，也不想删除python3的软链接，所以在网上查到了此方法

仔细看了下好像是升级python3.7后缺少了geventwebsocket这个模块

那我尝试了下pip安装这个模块：

sudo pip3 install geventwebsocket

结果还是报错

2、继续安装gevent-websocket

sudo pip3 install gevent-websocket

安装之后还有报错，提示No module named 'paramiko'

3、继续安装paramiko

 sudo pip3 install paramiko

4、接着重启宝塔面板

sudo /etc/init.d/bt

成功！！！
