Answer 1

If you encounter this problem you have to use sam build --use-container in other to go around the problem with the requirements.txt Its a well known issue and a GitHub issue has been submitted https://github.com/aws/aws-lambda-builders/issues/229#issuecomment-841407255

Answer 2

I had the same failure when my serverless application specified Runtime as python3.6, while the environment was using Python3.7.

thank you for your answers, it seems to be a well known issue with some dependencies and it requires the user to use sam build --use-container – Brashear
