Question

更改airflow.cfg后，运行命令“ airflow webserver” 出现以下错误：

  File "/home/airflow/.pyenv/versions/3.7.3/lib/python3.7/site-packages/airflow/contrib/auth/backends/password_auth.py", line 33, in <module>
    from flask_bcrypt import generate_password_hash, check_password_hash
ModuleNotFoundError: No module named 'flask_bcrypt'

...

File "/home/airflow/.pyenv/versions/3.7.3/lib/python3.7/site-packages/airflow/__init__.py", line 73, in load_login
    raise AirflowException("Failed to import authentication backend")
airflow.exceptions.AirflowException: Failed to import authentication backend

只需将内容添加到airflow.cfg文件中即可。

[webserver]
authenticate = True
auth_backend = airflow.contrib.auth.backends.password_auth

Answer 1

解决了。

pip install flask-bcrypt

Answer 2

pip3 install flask-bcrypt --user

是我的把戏。

Answer 3

解决此错误的官方方法是安装password子软件包，该子软件包将引入密码验证所需的依赖项。

pip install 'apache-airflow[password]'

in the airflow docs中提供了可用子软件包的列表。

更改airflow.cfg后无法导入身份验证后端
