When installing a package with homebrew, you’ll most likely get the latest version.

Usually that’s okay, but what if you need an older version of that package?

In such a scenario, you can install from an older formula url:

$ brew install <formula_url>

Example

Let’s say you want to install chromedriver version 2.22.

First, uninstall chromedriver if it’s already installed:

$ brew rm chromedriver

Now find the formula in homebrew-core:

The formula filename should be chromedriver.rb.

Open the file in GitHub and click History.

Use the commit message as a reference to find the version that you desire:

Open the file at that point in history.

Finally, click on Raw to get the url of the raw file.

Copy it and paste it after brew install:

$ brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/14c7f7415bd2feaf49def7ad53fe5f6eb32f9265/Formula/chromedriver.rb

Voila, you have an older version of chromedriver installed with brew!
