Before installing Homebrew you will need to install Rosetta2 emulator for the new ARM silicon (M1 chip). 1- install Rosetta2 via terminal using command line :

/usr/sbin/softwareupdate --install-rosetta --agree-to-license

This will install rosetta2 .

2- After installing Rosetta2 above you can then use the Homebrew cmd and install Homebrew for ARM M1 chip: using this command line:

arch -x86_64 /bin/bash -c "$(curl -fsSL raw.githubusercontent.com/Homebrew/install/..)"

3- Once Homebrew for M1 ARM is installed use this Homebrew command to install packages:

arch -x86_64 brew install
