An instillation of Capybara depends on two things: the Ruby programming language and Bundler, to manage the Ruby dependencies.
Let's check to see if you have Ruby on your local machine.
Open up your Mac terminal and type in:
We can see on this machine, yes, we do have Ruby.
If you don't have Ruby, the easiest way to install it is through Homebrew.
To check if you have Homebrew, type:
Yes. We do have Homebrew on this machine.
If you do not have Homebrew, just go to Homebrew website.
Select the line of installation code, copy it, and paste this in the Mac 0S terminal prompt.
Okay, let's paste it.
Since we already have Homebrew, let's abort this.
Once you have Brew installed, just type in
brew install ruby
and Ruby will start installing after updating Homebrew.
Next, we need to install Bundler.
Bundler will manage all of our Ruby dependencies.
To install Bundler in the Mac terminal, just type in:
gem install bundler
The two commands we'll be using most of all is
bundle install to update all of the Ruby dependencies of the project, and
bundle execute in order to execute our tests.
