Issue when installation of AWS-SAM-CLI in MacOS Mojave (10.14)

[selvaganeshi]

I tried to install SAM Cli from the following documentation.
https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-install-mac.html

The last step is giving the following error. But I have the Python updated and has both the system python (2.7) and also Python3 installed.

Hi, Thank you!
I installed Python via Homebrew and after running the below script it was working!

brew link --overwrite python
brew postinstall python

just doing brew postinstall python solved it for me.
