Apache Airflow 1.9从GitHub安装在debian 8上

Question

由于debian 9上的这个命令行,我从GitHub安装了Apache airflow 1.9: pip install git+https://github.com/apache/incubator-airflow.git@v1-9-stable

但是,我在airflow initdbFernet造成的错误中,你知道如何解决这个问题吗？

   INFO  [alembic.runtime.migration] Running upgrade 947454bf1dff -> d2ae31099d61, Increase text size for MySQL (not relevant for other DBs' text types)

如何pip install apache-airflow[gcp-api]从我之前使用GitHub的pip命令安装中指定extrapackage ？

如何安装最新的1.9.0RC？我有一个断言错误.

标记为好的答案有一个断开的链接,如果你像我一样登陆这里并继续破坏,这些步骤对我有用:

• pip install cryptography
• python -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())"
• 将生成的密钥添加到配置文件中airflow.cfg,fernet_key = YOUR_GENERATED_KEY
