How can I install Homebrew into /opt/?
I'm on the new M1 MacBook Pro. I'm trying to install gtk+3 (which has native apple silicon support) via Homebrew. First it told me
Cannot install in Homebrew on ARM processor in Intel default prefix (/usr/local)! Please create a new installation in /opt/homebrew using one of the "Alternative Installs" from: https://docs.brew.sh/Installation You can migrate your previously installed formula list with: brew bundle dump
I tried to run the terminal via Rosetta 2, but gtk+3 needs ARM support to install, so that didn't work.
I tried to manually unzip the code line in docs.brew.sh in /opt/ but it told me I don't have permission. I tried to sudo it, but to no avail. Any help?
Edit 1: for full message:
brew install gtk+3

Edit 2: Created a folder called 'Home-brew' in /opt/ and opened terminal there, tried sudo and everything:
oresttokovenko@Orests-MacBook-Pro-2 Homebrew % sudo chmod 755

Answer
I've used the script written by Noah Rubin;
/bin/bash -c "$(curl -fsSL https://gist.githubusercontent.com/nrubin29/bea5aa83e8dfa91370fe83b62dad6dfa/raw/48f48f7fef21abb308e129a80b3214c2538fc611/homebrew_m1.sh)"
worked like a charm! Here is his youtube video on this topic for more info; https://youtu.be/nv2ylxro7rM
Edit: Forgot to mention, this script installs the homebrew into /opt/homebrew
