AWS Lambda not importing LXML

Question

I am trying to use the LXML module within AWS Lambda and having no luck. I downloaded LXML using the following command:

pip install lxml -t folder
         


        

Answer 1

AWS Lambda use a special version of Linux (as far as I can see).

Using "pip install a_package -t folder" is the good thing to do usually as it will help to package your dependencies within the archive that will be sent to Lambda, but the libraries, and especially the binary libraries have to be compatible with the version of OS and Python on lambda.

You could use the xml module included in Python : https://docs.python.org/2/library/xml.etree.elementtree.html

If you really need lxml, this link gives some tricks on how to compile shared libraries for Lambda : http://www.perrygeo.com/running-python-with-compiled-code-on-aws-lambda.html
