When I run rails server, 'Could not find jsonapi-parser-0.1.1.beta2' error shows up.
~/ruby_on_rails/test/sampleapp$ rails s
Could not find jsonapi-parser-0.1.1.beta2 in any of the sources
Run `bundle install` to install missing gems.

Could not find jsonapi-0.1.1.beta4 in any of the sources
jsonapi beta4 is not available. only beta5, beta 1,beta2 are available. you could find this here
Add this line in your gemfile if not and then run bundle install.
gem 'jsonapi-parser', '~> 0.1.1.beta2'
gem 'jsonapi', '~> 0.1.1.beta5'
This might be due to the method which requires jsonparser which is not included in your rails app.
