"Import Error lxml" is shown in AWS Lambda

I am trying to run using pygal libray to show graph in AWS lambda.But this error is shown, even I have already installed lxml.deployment_package my_source_code import_error

Solution

  • It's because lxml contains binary pre-compiled libraries that it uses. When you install lxml locally on your Windows machine, you install a Windows-compatible version of it. However this is not compatible with the Lambda execution environment which is Linux based.

    So you have to create a Lambda compatible deployment package. You have couple of options doing so. You can use sam build --use-container, you can build the libraries in a Docker environment and then zip those, etc. See this answer as well.
