Python pytest键错误：'；用户'；在docker容器内

我正在构建一个docker容器来运行我的自动化测试。当我尝试运行下面的命令[这在本地和jenkins中有效]时，我得到以下错误：

我已经在容器中安装了Python 3.5.2，

您的映像中似乎没有定义“USER”环境变量。从外部定义它，或使您的代码适应它的缺失：

• 在代码中，使用

  os.getenv（'USER'，backup\u USER\u name）

  而不是

  os.environ['USER']

• 在代码中，而不是依赖您的环境来获取当前用户

导入getpass
打印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

  环境设置下添加
  USER:some\u USER\u name

---

更新：我也可以在容器中复制。谢谢！这就是问题所在。我很感谢你的帮助。从一开始就省去了很多步骤，这也毫无价值。现在运行'docker run-e USER=$（whoami）-it python bash'正在工作。在创建实际的dockerfile时，我将对此进行清理。
