This is a mess. I will edit it later

This is the command history to build a Lambda Layer in Python. I had to add a C compiler, Compile Python 3.9 with a specific requests module, and then upload to S3 and Add the Layer to Lambda function before I could use it but after all that, it worked.

Recently, I had the need to compile Python 3.9 on AWS CloudShell which was necessary to create a Lambda Layer for the requests module.

This required add a C compiler to CloudShell. The steps are:

Step 1: Update packages.

  sudo yum update

Step 2: Install GCC

  sudo yum groupinstall “Development Tools”

Step 3: Check version

  gcc –version

[cloudshell-user@ip-10-2-31-49]$ gcc –version
