【Docker】用docker部署superset碰到ModuleNotFoundError: No module named ‘gevent’

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:
superset_1 | File “/usr/local/lib/python3.6/site-packages/celery/__init__.py”, line 110, in _patch_gevent

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
[[email protected] 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。

回答

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)
