Erro ao executar o script twitter_hook

Boa tarde, quando tento executar o twitter_hook ele da a mensagem dizendo que o airflow não está sendo encontrado:

Traceback (most recent call last):
  File "twitter_hook.py", line 1, in <module>
    from airflow.hooks.http_hook import HttpHook
ModuleNotFoundError: No module named 'airflow'

Tentando um pip install airflow aparece o seguinte texto:
