Homebrew install specific version of formula?

Question

How do I install a specific version of a formula in homebrew? For example, postgresql-8.4.4 instead of the latest 9.0.

Answer 1

If you can't find your version with brew search , you can also try going over the commit logs for your formula to find the version you want:

here is an example for installing an older version of nginx via brew:

• ngxnx formula commit log

• see nginx: update 1.6.3 bottle eba75b9a1a474b9fc4df30bd0a32637fa31ec049

From there, we can install 1.6.3 with the sha and raw git url:

brew install https://raw.githubusercontent.com/Homebrew/homebrew/eba75b9a1a474b9fc4df30bd0a32637fa31ec049/Library/Formula/nginx.rb
