i beginner of ruby on rails , doing online assignment: https://drive.google.com/file/d/0bwvt4e6dqqn4zjgwdzfgazzbzve/view

repository: https://github.com/jhu-ep-coursera/fullstack-course1-module3

however, encountered problems (step 5 of getting started in file) when tried started.

the error got shown below:

an error occurred while loading ./spec/recipes_app_spec.rb. failure/error: capybara.default_driver = :poltergeist  nameerror: uninitialized constant capybara # ./spec/recipes_app_spec.rb:1:in `<top (required)>'   no examples found.   finished in 0.00034 seconds (files took 0.23609 seconds load) 0 examples, 0 failures, 1 error occurred outside of examples

how can fix problem? many thanks!!!

it means capybara not available in ruby on rails app. file called "gemfile" inside ror app, , inside gemfile line says:

gem 'capybara'

if don't see need add it. once you've done that, go console, go root directory of ror app , run

bundle install

once you've done that, in test helper file need add line

require 'capybara/rails'

there lot of information capybara available on github page located here: https://github.com/teamcapybara/capybara
