How can I use rack 1.3.0 with rails. I tried putting gem 'rack', '1.3.0' in Gemfile and did bundle update rack but it says
Bundler could not find compatible versions for gem "rack":
In Gemfile:
rails (= 3.0.9) depends on
rack (~> 1.2.1)
rack (1.3.0)
I am having issues with rack version <= 1.2.3 here lib/rack/utils.rb#L495. I don't see this in rack 1.3.0, so wanted to give a try. But clearly rails is not allowing to use rack 1.3.
Is there any workaround?
The short answer is: you can't use rack 1.3 with Rails 3.0. As the error states, Rails 3.0.9 depends on Rack 1.2.x with x >= 1.
If you need rack 1.3, you should try Rails 3.1 which currently depends on rack ~> 1.3.2 (i.e. 1.3.x with x >= 2). An alternative could be to change the actionpack gemspec locally to require rack 1.3. But then you are on your own and there will probably be grues coming out of holes and eating all your loved ones...

How to upgrade the rack gem from v2 to v3 for rails 7?
If you try to use:
gem 'rack', '>= 3'
Bundle will show you the result of the upgrade:
Bundler could not find compatible versions for gem "rack":
In Gemfile:
rack (>= 3)
rails (~> 7.0.4) was resolved to 7.0.4, which depends on
actionpack (= 7.0.4) was resolved to 7.0.4, which depends on
rack (~> 2.0, >= 2.2.0)
For the beginning of 2023 it's not possible to upgrade rack to v3 for rails v7.0 because it's not prepared yet. Please follow this PR to get the latest information on the ongoing process:
https://github.com/rails/rails/pull/46594
https://github.com/rails/rails/pull/47052
I am using Administrate in my rails app, it is upgraded from 0.9.0 to 0.15.0 version. After that rack is upgraded to 2.2.3 as following.
I also using grape and wine_bouncer with Doorkeeper for authorization.
wine_bouncer requires Grape > 0.10 and < 1.2
Due to this incompatible version issue, I want to keep my rack version as 2.0.8 and grape is 1.2.5. How can I force rack down to 2.0.8? I don't see rack in gemfile.
Add to Gemfile gem 'rack', '= 2.0.8' and after run bundle command. Now rack version is 2.0.8
I have to bring a fix that was made on rack 1.4.5 to my 1.36 rack. Can not upgrade rack as ruby is not happy with it
Bundler could not find compatible versions for gem "rack":
In Gemfile:
sass-rails (~> 3.1.4) ruby depends on
rack (~> 1.3.6) ruby
rack (1.4.5)
w/o this fix (https://github.com/rack/rack/blob/rack-1.4/lib/rack/deflater.rb), my app error is randomly throwing app errors.
What is the best way to just bring this change without having to change the version.
Thank you so much for your help!

2 ways comes to my mind
either monkey patching
or
creating a repo fork from 1.3.6 version patching that and using that repo.
I'm trying to get Helios (https://github.com/helios-framework/helios) to work with an existing Ruby on Rails 3.1 application. But there's a conflict regarding rack version; bundle install gives me this:
Bundler could not find compatible versions for gem "rack":
In Gemfile:
helios (>= 0) ruby depends on
rack (~> 1.4) ruby
rails (>= 3.1) ruby depends on
rack (1.3.9)
Any ideas on how to proceed?
My setup: Rails 3.0.9, Ruby 1.9.2
I want to check the gem version for my app through the Rails console. In my gemfile, I have
gem 'rack', '1.2.3'
Ran bundle install after. In the Rails console,
>> Rack.version
=> "1.1"
Any idea why?
UPDATE
Gemfile.lock
GEM
remote: http://rubygems.org/
specs:
actionpack (3.0.9)
...
rack (~> 1.2.1)
...
rack (1.2.3)
rack-mount (0.6.14)
rack (>= 1.0.0)
warden (1.0.4)
rack (>= 1.0)
DEPENDENCIES
...
rack (= 1.2.3)
...
There are several rack versions listed in gemfile.lock.
Rack.version
will return the protocol version,
Rack.release
is probably what you are you looking for.
https://github.com/rack/rack/blob/master/lib/rack.rb#L14
Otherwise:
Gem.loaded_specs["rack"]
Example:
Gem.loaded_specs["rack"]
# => #<Gem::Specification name=rack version=1.3.2>
Gem.loaded_specs["rack"].version
# => #<Gem::Version "1.3.2">
Gem.loaded_specs["rack"].version.to_s
# => "1.3.2"
Every gem has ::VERSION constant..
so just use Rack::VERSION or OpenSSL::VERSION in console which should give you the version of gem loaded in that console.
we can use bundle list or bundle show to list all Gems included by the bundle.
Maybe you have multiple version of rack installed, try running gem uninstall rack and see if it offers you two options to choose from, Rack 1.1 and Rack 1.2.3. If so, choose to uninstall Rack 1.1.
If this still does not work, just uninstall Rack and try running bundle update.
I had this problem when I was using multiple rake versions 0.8.7 and 0.9.2, this helped me.
