rubygems - How to install a downloaded Ruby gem file?

Question

How does "gem install" works ? It is not intuitive...

My gem is really here :

[root@localhost Téléchargement]# ll *.gem
-rw-rw-r-- 1 jean jean 16353818 mar  5 11:39 ruby-processing-1.0.9.gem

But an idiomatic "gem install" does not see it...

[root@localhost Téléchargement]# gem install  ruby-processing-1.0.9.gem 
ERROR:  could not find gem ruby-processing-1.0.9.gem locally or in a repository

What's wrong with that ?

Maybe I have not fully understood the question. But if you just want to install a gem that you have on your local machine, all you need to do from the console is go into the directory containing your gem and gem install --local your.gem.
