How can i resolve the problem?

Answer 1

You don't need to include rails-api gem in your Rails 5 app's Gemfile. It's already merged into Rails 5.

Reference

Answer 2

I tried all the above suggestion from Babar but didn't work, so i tried one little thing that work which is adding gem 'listen' to the gem file. it works for me!!

Answer 3

rails-api generate scaffold user email:string password:string auth_token:string

No need of writing rails-api, just use rails. Rails::API has been merged into Rails 5.0, so no need of gem 'rails-api'.So remove it from gemfile.After than you may get error when you try to migrate.So you have to include listen gem.
