Errors in Gemfile - ruby-on-rails

Question

I've cloned my app from Github but I've got errors on Gemfile. So I think, this app. is still running on heroku and it said that all up to date when I've used following commands:
git status
//On branch master
Your branch is up-to-date with 'origin/master'.
nothing to commit, working tree clean
git push heroku
//Everything up-to-date
Also I could see output in heroku.
How to fix the error in Gemfile?
thanks.
//error as below:
There was an error parsing `Gemfile`: The `branch` option for `gem 'recaptcha'` is not allowed. Only gems with a git source can specify a branch. Bundler cannot continue.

I took off branch but got error as below when run bundle install:
bundle install
"Your Ruby version is 2.3.0, but your Gemfile specified 1.9.3"
Version 2.4 create the same error. So,I've changed to 2.3.0 - it went through until another error as below:
Results logged to
/usr/local/rvm/gems/ruby-2.3.0/extensions/x86_64-linux/2.3.0/json-1.7.5/gem_make.out
An error occurred while installing json (1.7.5), and Bundler cannot continue.
Make sure that gem install json -v '1.7.5' succeeds before bundling.

I've follow the answer suggested to use the old version 1.9.2 and I be able to use command bundle install but after pushing to heroku, I've got empty page on heroku and errors as below:

When I took off suggested line( with recaptcha), I could not see app. locally.
With this line I could see app. locally.
Errors without this line as below:

Answer 1

1- In reCAPTCHA project on Github there is not a branch rails3, so, remove that piece of your Gemfile.
gem 'recaptcha', :require => 'recaptcha/rails'
2- Since you are using ruby 2.2.x, and in Gemfile is 1.9.3 I suggest that you should install 1.9.3 (via rvm or via rvm or whatever you use to manage your ruby versions) in your machine and work with that in order to avoid other conflicts you may find, because you are using a legacy code.
rvm install 1.9.3
rvm use 1.9.3
now install gem bundler and after that blundle install your Gemfile

Answer 2

I did not get this error using Ruby 2.4.1. I did get the same error when I changed versions to 1.9.3, as specified in the Gemfile. I also don't see a branch called rails3 at the source on Github. I would try removing the branch option first.
gem 'recaptcha', require: 'recaptcha/rails'
