Now that we have Homebrew installed, we are finally ready to install CouchDB.
Please note that before Homebrew installs CouchDB, it will install all of its dependencies, which include such things as: Erlang, Spidermonkey, ICU, and so on. This section might take up to 10-15 minutes to complete, because they are being compiled locally on your machine. Don't worry if it seems like it's taking too long; this is normal.
We are going to install CouchDB using Homebrew.
brew install couchdb -v
