C compiler can't create executables

Question

I'm trying to install the elastic beanstalk cli, like so:

./aws-elastic-beanstalk-cli-setup/scripts/bundled_installer

But I'm getting the following error:

python-build: use openssl from homebrew
python-build: use readline from homebrew
Downloading Python-3.7.2.tar.xz...

For some reason, the installation script isn't detecting the C compiler. Of course, both the gcc and the cc commands work in the terminal. I'm using macOS 11.1. How do I fix this?

You need to run the commands using Roseta, and arch command can be used to run commands via Rosetta:

arch -x86_64 ./aws-elastic-beanstalk-cli-setup/scripts/bundled_installer
