Question

I ran the brew command to install Facebook homebrew tap. I have a M1 Apple Silicon Chipset and use a terminal under Rosetta for brew commands.

brew tap facebook/fb

I got the error message:

I searched for the facebook/fb tap on Google, I found a GitHib repo but reporting errors is unactivated: https://github.com/facebook/homebrew-fb

Answer 1

The simplest solution you can do is fork the Facebook/FB repository into your GitHub account then change the 19th line in buck.rb file. It should be like this:

old one: depends_on java: "1.8"

new one: depends_on "openjdk@8"

The reason we do this Buck still relies on Java 8. After you do this you can simply open your terminal and write:

brew tap {yourGithubAccountName}/homebrew-fb

then

brew install buck
