Unable to import module 'lambda_function': No module named 'bcrypt'

Question

Unable to import module 'lambda_function': No module named 'bcrypt'

I get the above error when I import bcrypt in my python code on AWS Lambda

My Python version is 3.8 and I've added python bcrypt 3.2.0 as a layer to my lambda function. There tutorial I referred to add Layers to Lambda is here

The file structure for my bcrypt layer is ./python/bcryptfiles (bcryptfiles is my bcrypt package)

I initially included the bcrypt package as a folder adjecent to my lambda_function.py file, which solved bcrypt import issue. But when I invoked checkpw, I got the error module 'bcrypt' has no attribute 'checkpw'

Can someone please suggest a solution? I couldn't find questions related to python bcrypt in AWS Lambda, hence raise this issue.

As this bcrypt should be a library installed as a layer, you shouldn't need to add it adjacent to your lambda_handler.py file.

Also, you would probably need an amazon linux build (amazon linux 2 for python 3.8) to run it on this runtime.

One method that has helped me build unavailable packages in the past was this: https://github.com/lambci/docker-lambda
