updated rack from 2.2.7 to 3.0.8 now I'm getting the following error after running bundle install:
C:/Ruby30-x64/lib/ruby/site_ruby/3.0.0/rubygems.rb:265:in `find_spec_for_exe': can't find gem rack (>= 0.a) with executable rackup (Gem::GemNotFoundException)
from C:/Ruby30-x64/lib/ruby/site_ruby/3.0.0/rubygems.rb:284:in `activate_bin_path'
from C:/Ruby30-x64/bin/rackup:25:in `<main>'
the error started when the gem rack-session apparently was requiring an newer version or rack:
C:/Ruby30-x64/lib/ruby/gems/3.0.0/gems/rack-2.2.7/lib/rack/session/cookie.rb:155:in `<class:Cookie>': undefined method `DelegateClass' for Rack::Session::Cookie:Class
so I updated it to the latest version, and removed the older version of rack, now I'm getting the error, what do I do?
The rackup executable was extracted from rack to the separate rackup gem since rack 3.0.0. Thus, to use the rackup command with rack >= 3.0, you also have to add
gem "rackup"
to your Gemfile.
