相关疑难解决方法(0)

我正在尝试使用 Airflow 和 Postgres 构建一个 docker 容器，但在构建过程中出现了许多错误，如下所示。我尝试过降级，markupsafe如下requirements.txt所示，但没有帮助。我可以做什么来解决这个问题？

# I tried this version:
markupsafe==2.1.1
# and then also this one:
markupsafe==2.0.1

错误信息：

ImportError: cannot import name 'soft_unicode' from 'markupsafe' (/usr/local/lib/python3.7/site-packages/markupsafe/__init__.py)

我的docker-compose.yml：

version: '3'
services:
  postgres:
    image: postgres:11.2
    environment:
      - POSTGRES_USER=airflow
      - POSTGRES_PASSWORD=airflow
