If you post your Gemfile & Gemfile.lock this would be easier to help debug. (If you're pointing to any gems/code from private repos make sure you remove the username/password from the appropriate fields) – Jay Dorsey

your rspec-rails blocks the upgrade. That bundler output shows this part:

actionpack (< 4.3, >= 3.0)

So rspec-rails blocks anything bigger that 4.2.

Release the rspec-rails contraint ~> 3.4.2 to something more relaxed like ~> 3.5 and try again 

bundle update rails rspec-rails

In general, when upgrading Rails, try bundle update rails together with all the Gems that have specific version requirements for Rails or that are mentioned from bundler.

That happened to me when I was trying to update to rails 6. here is my workaround.

source 'https://rubygems.org'
git_source(:github) { |repo| "https://github.com/#{repo}.git" }

ruby '2.6.3'


gem 'rails', '6.0.0.rc1'
gem 'sqlite3'
gem 'activerecord-jdbcsqlite3-adapter', platforms: [:jruby]
gem 'activerecord-import'
gem 'bootsnap'
gem "rspec"


group :development do
  # Access an interactive console on exception pages or by calling 'console' anywhere in the code.
  gem 'web-console', '>= 3.3.0'
  gem 'listen', '>= 3.0.5', '< 3.2'
  # Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring
  gem 'spring'
  gem 'spring-watcher-listen', '~> 2.0.0'
end

platforms :rbx do
  gem 'rubysl', '~> 2.0'
  gem 'rubinius-developer_tools'
end

Remove your Gemfile.lock and add this to your Gemfile:

source 'https://rubygems.org'

and don't forget to update your other gems.

I have faced this issue when I used these gems with versions:

  • gem 'rspec-rails', '~> 3.4.2'
  • gem 'factory_girl_rails', '~> 4.7.0'

It worked for me after removing gem version from specified gem.

  • gem 'rspec-rails'
  • gem 'factory_girl_rails'
