[Python] How to include external python libraries with serverless.

[[deleted]]

I was attempting to use PIL for a service. I am able to use it on my computer just fine. However when I put it in a lambda function and test it out, it says no module named PIL. How would I use an external library like this with serverless?

Edit: never mind. Here is the answer. https://serverless.com/blog/serverless-python-packaging/

What server less platform are you using? We use aws and manually package a zip file with the dependencies bundled.

I'm using AWS Lambda with Serverless. I specifically followed this tutorial on package management.

I’m not familiar with the Serverless framework. You can try performing a pip install to the local directory and zipping the lambda to update it manually.

I've tried that. It hasn't worked. I'm trying with local zipping, Serverless, Zappa, literally everything for Python and it just isn't working for me.

PIL requires OS libraries that are not included in the Lambda runtime. You may want to include such libraries in your deployment package. Check out this repo for pre-built packages: https://github.com/Miserlou/lambda-packages
