aws-sam-cli: ModuleNotFoundError: No module named 'configparser'

Description:

I downloaded and installed the SAM CLI, and when I try to validate a template, I get a “ModuleNotFound” error

Steps to reproduce:

Download and install SAM CLI:

wget https://github.com/aws/aws-sam-cli/releases/latest/download/aws-sam-cli-linux-x86_64.zip
unzip aws-sam-cli-linux-x86_64.zip -d sam-installation
sudo sam-installation/install
rm -rf aws-sam-cli-linux-x86_64.zip sam-installation/

Then attempt to validate a template:

sam validate

We are working on a fix for this issue, meanwhile please follow @iongion’s recommendation of using version 1.23.0 as a workaround.
