You are using a very outdated version of SAM CLI (latest is 0.34.0). So I would start with upgrading.

This looks like it could be an outdated version of something related to ssl (guessing based on the stack trace). Upgrading should resolve this.

This doesn't look like a bug. Closing. Please reopen if you need help

I seem to have hit this same issue when installing aws-sam-cli version 0.41.0. I'm on Mac and have a very similar error stack. This is the first time I've tried installing aws-sam-cli. I have spent a long time trying to fix this and am giving up now. If anyone has managed to resolve this (maybe @lp060?) I'd appreciate any pointers.

In case it's useful:

➜  ~ python --version
Python 2.7.16
➜  ~ python3 --version
Python 3.8.1
➜  ~ pip --version
pip 20.0.2 from /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/pip (python 3.8)

I am seeing this exact same issue with sam v1.2.0 when running any command.

Can someone please provide any pointers on how I can resolve this?
