No module named 'lxml.etree'

I’m getting an No module named 'lxml.etree' issue. When built on codebuild vs codepipeline I don’t get this issue:

I download precompiled binaries for psycopg2 right now but I have not needed to do it for lxml. This looks like a difference between the docker-lambda image vs the real image.

Any ideas?

I just tried a simple function that has psycopg2-binary and lxml as a dependency in the requirements.txt file. I was able to import both in the function without the function crashing (complaining about not being importable). I did use sam build to build the function. So either docker-lambda solved this or sam build make it so you don’t need to worry about it. Either way, I can’t reproduce this issue.

Closing this as it seems to be resolved. If not, please cut a new issue.

I just downloaded the precompiled binaries for lxml and got around the issue for sam build. I think they are still required locally (sam build) but not in prod but I have not checked since Sept.
