aws-sam-cli installation fails on macOS 11.3.1 because of missing python@3.8

[ericHgorski]

Im trying to get up and running with aws-sam-cli with homebrew. I've tried various proposed fixes here and elsewhere on the web but havent been able to make it past the following error:

==> Searching for similarly named formulae...
Error: No similarly named formulae found.
Error: No available formula with the name "python@3.8" (dependency of aws/tap/aws-sam-cli).
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching taps on GitHub...
Error: No formulae found in taps.```

My brew version is `Homebrew 3.1.11-45-g33e71c9`.

I run these commands, and then the ones to install aws.sam-cli,
I got several erros but by executing the same solutions it suggest, at the end, it worked

rm -rf /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core;
brew update

The solution posted by @silvanojulio-haul worked for me

Had the same issue, had to remove /opt/homebrew/Library/Taps/homebrew/homebrew-core folder and it solved the issue. Thanks!

Worked for me as well

[brigandimedacta]

i run brew doctor and fix the warning with the commands that show up.
After the sam-cli installation works.

Thanks , @brigandimedacta brew doctor solved the issue for me.
Below is the output of the it.

Warning: Homebrew/homebrew-core was not tapped properly! Run:
  rm -rf "/opt/homebrew/Library/Taps/homebrew/homebrew-core"
  brew tap homebrew/core

running both commands solved issue for me.

I had to add the below 3 lines into ~/.zshrc after installing python3.8 with brew install --build-from-source python@3.8 on my MacBook M1 2020 -

export LDFLAGS="-L/opt/homebrew/opt/python@3.8/lib"
export PKG_CONFIG_PATH="/opt/homebrew/opt/python@3.8/lib/pkgconfig"
export PATH="/opt/homebrew/opt/python@3.8/bin:$PATH"
