arm64 macOS ("Apple Silicon", "M1") install friction

1. Please specify the following:

• OS: [e.g. OS X, Ubuntu, Windows, etc.]: macOS Big Sur 11.0.1
• Shell (Bash, PowerShell, Zsh, etc.): Zsh

2. Description This is informational, for those looking to run eb on their ARM Macs.

1. Python 3.7.2 doesn’t build under macOS arm64. Update this line to refer to 3.9.1, which does build. You may have to follow pyenv’s docs to ensure you have the prerequisite software installed.
2. With a usable Python installed, rerun the eb installer. It may fail while installing cryptography into a virtualenv; see https://github.com/pyca/cryptography/issues/5702. If so, you’ll have to build it from source. To do this, follow the instructions here to get prereqs, then finally rerun the eb installer script with the flags the cryptography build docs prescribe:

LDFLAGS="-L$(brew --prefix openssl@1.1)/lib" CFLAGS="-I$(brew --prefix openssl@1.1)/include" ./scripts/bundled_installer

1. Follow the “Finishing up” instructions from the eb installer.

Regarding @hishamMounir’s approach, that worked for me after installing python with pyenv I did: brew install awsebcli and everything worked.

I had to install Python manually then, I built cryptgraphy and installed, then I used Homebrew to install the ebcli package instead of building the script, and it worked
