Closing as duplicate #8512. You can also install airflow using pinned requirements that are already released in 1.10.10. See also #8513 with detail description of repeatable installation process.
I see they already updated setup.py in airflow to use 2.2.1 https://github.com/apache/airflow/blob/1d5d6613a14ae3120093979cb31ae8b0de90c2d4/setup.py#L601, but not released it yet.
