用docker部署superset碰到ModuleNotFoundError: No module named 'gevent'

Question

问题：用dokcer部署superset时没碰到什么问题，但是一启动就报如标题的错误。

报错：

补充信息：我这个centos7系统之前装过好几个python，平时使用python时，查找包的地址和报错里是不一样，如下
[root@rac1 docker]# ls -lh /usr/bin/ |grep python
lrwxrwxrwx 1 root root 27 May 6 07:59 pip3 -> /usr/local/python3/bin/pip3
lrwxrwxrwx 1 root root 7 May 5 12:12 python -> python2
lrwxrwxrwx 1 root root 9 May 5 12:12 python2 -> python2.7
-rwxr-xr-x 1 root root 7.1K Apr 9 22:31 python2.7
lrwxrwxrwx 1 root root 32 May 6 07:59 python3 -> /usr/local/python3/bin/python3.6

求救：我想知道怎么在docker里补上包啊，启动不了的情况下！docker不是一切都是自带吗？库竟然还要我自己下载？！是不是镜像问题啊。

问题原因：
某个py文件代码中导入了'gevent'包，但是docker容器里没有安装该包，运行到这一步就会报错。

解决方法：

• 找到该py文件，将导入'gevent'相关的语句先注释掉。
• 进入容器命令行
  docker exec -it container_id(容器id) bash
• 命令行安装'gevent'包
  pip install gevent
• 将修改的docker提交生成新的image
  docker commit -m "修改备注" new_iamges(镜像名):v1(版本号)
• 查看新的docker镜像
  docker images
• 删除原有容器
  docker rm container_id
• 重新构建容器
  docker run -d --name newcontainer -p 8080:8080 new_iamges:v1 cmd(执行命令)
