背景：
因服務器部署了flask項目，安裝了python3，故重啟寶塔面板報錯

解決辦法：
1、python3安裝geventwebsocket
我不想拆卸python3，也不想刪除python3的軟鏈接，所以在網上查到了此方法
仔細看了下好像是升級python3.7后缺少了geventwebsocket這個模塊
那我嘗試了下pip安裝這個模塊：
1 sudo pip3 install geventwebsocket
結果還是報錯
2、繼續安裝gevent-websocket
1 sudo pip3 install gevent-websocket
安裝之后還有報錯，提示No module named 'paramiko'
3、繼續安裝paramiko
1 sudo pip3 install paramiko
4、接着重啟寶塔面板
1 sudo /etc/init.d/bt
成功！！！
