brew bundle
brew bundle --global

Downgrade an application to a non-managed version

The easy way

brew unlink kubernetes-helm
#install version 2.13.0
brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/ed9dcb2cb455a816f744c3ad4ab5c18a0d335763/Formula/kubernetes-helm.rb
brew switch kubernetes-helm 2.13.0

The hard way

source alternative source

formula_name='kubernetes-helm'
formula_version='2.13.1'

cd $(brew --repository)/Library/Tapshomebrew/homebrew-core
git log master -S${formula_version} -- Formula/${formula_name}.rb
commit_id='<something>'  # insert commit id

git checkout -b ${formula_name}-${formula_version} ${commit_id}
HOMEBREW_NO_AUTO_UPDATE=1 brew install ${formula_name}
# pin application if needed

git checkout master
git branch -d ${formula_name}-${formula_version}

Gotchas

  • moreutils installs its own old version of parallel, which conflicts with the parallel formulae; install the standalone gettext, parallel and sponge to have their recent version
