Я использую приложение airflow на моем сервере Linux.
note - Airflow - это платформа для программного программирования, планирования и мониторинга рабочих процессов.
по какой-то неясной причине возникают следующие проблемы (когда мы перезапускаем поток воздуха или инициализируем базу данных,)
что я должен проверить относительно следующих ошибок?

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support
