Resolving glibc errors with python module

We recently switched out our lambda build image to a debian based image and started receiving errors around glibc.

[ERROR] Runtime.ImportModuleError. Unable to import module 'app':
/lib64/ version 'GLIBC_2.28' not found
(required by /var/task/cryptography/hazmat/bidnings/

After some googling we realized pip chooses the correct wheel for us and since we were running pip on a different machine than we were running our Python program on, we needed to let pip know about this.

RHEL/CentOS are using manylinux2014 which is what we need to pass to pip

--platform manylinux2014_x86_64

Additionally we do not want to use source packages, so we had to pass


Our final command ended up being

python3 -m pip install --platform manylinux2014_x86_64 --only-binary=:all: -r requirements.txt
