Hi,

I’m having some problems running a self made generator. When I want to  
list the generators with: rails g, my generator shows up in the list.  
But when I want to run it, I get Could not find generator error.

module MyGem  
module Core  
class InstallGenerator \< Rails::Generators::Base  
source\_root File.expand\_path(’…/templates’, **FILE** )

```
        def copy_initializer
            delete_stylesheets
            copy_stylesheets
        end

        private

        def delete_stylesheets
            remove_file "public/stylesheets/style.css"
        end

        def copy_stylesheets
            copy_file "stylesheets/style.css",

```

“public/stylesheets/style.css”  
end  
end  
end  
end

Anyone who has an idea what might be wrong?

it looks like it has something to do with my namespacing. When I create  
a second generator without namespaces, everything seems to work fine.

Does anyone know what to do in case of namespacing?
