我是 docker 的新手，所以我不明白是什么导致了这个错误。
我从 ubuntu 作为我的基础开始 [当使用 https://hub.docker.com/_/python/ 作为我的基础时也会发生这种情况]

我已经在容器
中安装了Python3.5.2
'USER' 环境变量似乎没有在您的图像中定义。在外部定义它，或者使您的代码在没有它的情况下具有弹性：
- 在您的代码中，使用
os.getenv('USER', backup_user_name) 而不是 os.environ['USER']
- 在您的代码中，use
getpass而不是依赖您的环境来获取当前用户。
import getpass
print getpass.getuser()
- 在
docker run 中，您可以添加 -e USER=$(whoami) 或类似的内容
- 在
docker-compose 中，您可以在该服务的 environ 设置下添加 USER: some_user_name。
