Question

I created a fresh project using rails new Project -d=postgresql. If I then run rails server, I get the following error message:

C:/GemRepository/gems/actionpack-3.1.3/lib/action_dispatch.rb:34:in `require': cannot load such file -- active_model (LoadError)
    from C:/GemRepository/gems/actionpack-3.1.3/lib/action_dispatch.rb:34:in `<top (required)>'
    from C:/GemRepository/gems/railties-3.1.3/lib/rails/commands/server.rb:3:in `require'
    from C:/GemRepository/gems/railties-3.1.3/lib/rails/commands/server.rb:3:in `<top (required)>'
    from C:/GemRepository/gems/railties-3.1.3/lib/rails/commands.rb:48:in `require'
    from C:/GemRepository/gems/railties-3.1.3/lib/rails/commands.rb:48:in `<top (required)>'
    from script/rails:6:in `require'
    from script/rails:6:in `<main>'

I also tried

gem which active_model

which returned

C:/GemRepository/gems/activemodel-3.1.1/lib/active_model.rb

Please help me.

Answer 1

Well, I managed to solve it.

I restarted my computer, deleted everything from my gem repository, reinstalled rubygems (ruby setup.rb) and reinstalled rails (gem install rails).

Thanks anyway 🙂
