Install a previous version of chromedriver with brew

I want to install chromedriver version 79.0.3945.36 with brew. When I try to run

 brew cask install [email protected]

It fails saying [email protected] is unavailable: No Cask with this name exists.

Solution

I did a quick check, did not find cask formula has versioned ones.

The hack way of installing a old version of cask formula would be:

cd /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask, go the place where cask is referenced
git reset --hard c3c1b84b7a, this would effective set chromedriver to v79.0.3945.36
git checkout -b temp, checkout a new branch, which prevents brew auto-refresh your local master
brew install --cask chromedriver, this would install your desired version.

After that you can always do git checkout master and brew up to keep in sync with the latest master of homebrew-cask.

here is my installation log
