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

22 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！！！
