Problem with ARM package selection when installing homebrew git on an Intel MacBook Air

Question

I was trying to install homebrew git but I got this Error: Cannot install on Intel processor in ARM default prefix (/opt/homebrew)!

I have an Intel processor MacBook Air (13-inch, Early 2015) running macOS Monterey 12.6.5

To install brew - the first step seemed OK:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

I then want to install a different git with brew install git and that's when the error happens. What might I do to understand / fix this?

Answer 1

For whatever reason your homebrew installation ended up in the wrong directory. To fix, do the following

• sudo rm -r /opt/homebrew
• Quit (Cmd-Q) Terminal and restart it
• /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

After the installation, run type brew again. If it returns /usr/local/bin/brew, you are all set.
