如何解决Apache中的SQLAlchemy强制错误？

我使用的是ApacheAirfow版本：1.9 并在启动

Web服务器后获取以下错误：

File "/usr/local/lib/python3.6/site-packages/airflow/utils/db.py", line 50, in wrapper
    result = func(*args, **kwargs)
  File "/usr/local/lib/python3.6/site-packages/airflow/models.py", line 3181, in is_paused
    return qry.value('is_paused')
  File "<string>", line 2, in value

    else "column",

有人知道这里应该做什么吗


有没有一个版本的SQLAlchemy不会出现这个问题
在
Dockerfile
中安装时，是否可以编写Apache应用程序来下载并使用该版本
我看到，即使是ApacheAirflow1.10也在做同样的事情。假设它也必须使用SQLAlchemy版本>=1.4，它是否也应该抛出错误
编辑Dockerfile后，您是否可以确认您的Airflow确实在使用SQLAlchemy==1.3.15？部署日志会输出在系统上找到的SQLAlchemy版本已通过第一个命令卸载。而1.3.15版本安装在第二个版本的系统上。但是，我仍在确认。但是这些命令能解决这个问题吗？1.9已经很旧了，您可能需要进一步降低SQLAlchemy的级别，即1.2.x
RUN set -ex pip uninstall SQLAlchemy
RUN set -ex pip install 'SQLAlchemy==1.3.15'
