What could prevent the creation of a gem specification file?

Question

I tried to update the specs on a gem that didn't have a .specification file.

1. cd {application_home_directory}
2. rake gems:refresh_specs

When I did, I received the recursive warning:

config.gem: Unpacked gem in vendor/gems has no specification file. 
Run 'rake gems:refresh_specs' to fix this.

I've also tried this, which also fails to create a specification without any error/warning:

1. cd vendor/gems/gemname
2. gem specification gemname > .specification

What could prevent the creation of a gem specification file in these cases?

Answer 1

Do you have config.gem statements for your gems in your environment.rb file? In my experience, you need to have the gems set up in your configuration in order for rake gems:refresh_specs to know about them.
