When I run the command: bundle exec rspec spec\features\01_visit_home_spec.rb , I get the below error.

To add this, when I executed "bundle install" at first, ffi gem is not listed in the installed gem files. And the above image(error) shows the dependency on ffi gem.
I tried to install ffi gem individually and then run the test. It still failed, displaying the same error.
Please help.
