I tried to deploy my Flask app with zappa==0.52.0, but I get an error as below;

ERROR: Double requirement given: setuptools (already in setuptools==52.0.0.post20210125, name='setuptools') WARNING: You are using pip version 20.2.3; however, version 21.1.3 is available. You should consider upgrading via the '/Users/yoonshinkwark/Documents/JBR_reco_local_2/JBR_reco_API_2/dola-aldagram/aws-flask38/bin/python3.8 -m pip install --upgrade pip' command. Oh no! An error occurred! :(

The version of Python is 3.8.8.

There is already an issue in the zappa github: https://github.com/zappa/Zappa/issues/995

The problem is that zappa adds setup-tools to its dependencies but the latest release of pip-tools (6.2.0) does the same now.

As a quick fix, you can pin pip-tools to version 6.1.0 in your requirements.txt
