updating mongoid gem to verison 5.0.0 and rails to 4.0.0, it is giving issue "Bundler could not find compatible versions for gem "railties"

Question

while running Bundle install following error is coming

Bundler could not find compatible versions for gem "railties":

In Gemfile: devise (~> 3.2.4) was resolved to 3.2.4, which depends on railties (< 5, >= 3.2.6)

factory_girl_rails (~> 4.4.0) was resolved to 4.4.1, which depends on
  railties (>= 3.0.0)

jquery-payment-rails was resolved to 0.0.1, which depends on
  railties (~> 4.0.0)

jquery-rails (~> 3.0.0) was resolved to 3.0.4, which depends on
  railties (< 5.0, >= 3.0)

rails (~> 4.0.0) was resolved to 4.0.0, which depends on
  railties (= 4.0.0)

rspec-rails (~> 3.4.0) was resolved to 3.4.2, which depends on
  railties (< 4.3, >= 3.0)

sass-rails (~> 3.2.3) was resolved to 3.2.3, which depends on
  railties (~> 3.2.0.beta)

I have removed gemfile.lock file also, still it is giving issue

Ok, here's a little analysis on the situation on railties version requirements given the error given to you:

1) railties (>= 3.0.0)
2) railties (~> 4.0.0) => (< 4.1, >= 4.0.0)
3) railties (< 5.0, >= 3.0)
4) railties (= 4.0.0)
5) railties (< 4.3, >= 3.0)
6) railties (~> 3.2.0.beta) => (< 3.2.1, >= 3.2.0.beta)

All version dependencies here can coexist except 6) which comes from sass-rails gem. Try to update to latest version sass-rails and you'll be fine (5.0.4 is the latest release) since it uses railties (>= 4.0.0, < 5.0). Also, all sass-rails versions after 4.0.0 will work too since that's when the railties dependency changed - see this.

Update

I've checked your Gemfile and the minimum changes that you could do in order to get the desired mongo version is the following (changes are commented):

ruby '2.2.2'
## Sinatra App Gems
gem 'sinatra',      '~> 1.4.4'
gem 'sass',         '~> 3.4.13'

gem 'sinatra-env',  '~> 0.0.2'

end

group :development, :test do

group :test do
  gem 'database_cleaner',     '~> 1.5.1'
  gem 'faker',                '~> 1.5.0'
end

You should probably run bundle update after this changes, but be careful since this updates ALL gems according to your Gemfile.

updating mongoid gem to verison 5.0.0 and rails to 4.0.0, it is giving issue "Bundler could not find compatible versions for gem "railties"
