Clean your Gemfile, removing the merge conflicts and try again. Also verify the Rails version you need:
source 'https://rubygems.org'
git_source(:github) do |repo_name|
repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("https://stackoverflow.com/")
"https://github.com/#{repo_name}.git"
end
