Question

So I was trying to configure my rails 3.0.9 app to use HTTPS and SSL by adding the following line to my environment configuration

config.middleware.insert_before ActionDispatch::Static, "Rack::SSL"

and defining Rack::SSL dependency in my Gemfile

gem 'rack-ssl', :require => 'rack/ssl'

For some reason that didn’t work so I tried to roll back the gem dependency first by undoing the above and then

gem cleanup

that didn’t work so I did the following stupid thing:

gem uninstall rack-ssl

and

gem uninstall railties

which uninstalled both railties 3.0.9 and 3.1.0.

Obviously I did a few bad things along the way but now I can’t run rails and I get the following error:

Can anyone help me? I tried uninstalling and reinstalling the rails gem but nothing’s working.

edit: I realized that switching to the system version of ruby (from my rvm default) fixed the problem, so I uninstalled and then reinstalled rvm, ruby, rails, and all of my gems. That didn’t entirely fix the problem, but I decided to take a quick look at my Gemfile.lock and noticed that rack-ssl was still in there. Deleting that did the trick.

Answer 1

You should be able to restore it with gem install railties -v 3.0.9
