问题
When I download something using gem I'd like to be able to just download the gem, and then choose whether or not I want to install it. I'm asking this because I'd like to install a particular gem on more than one computers ( without installing from the internet on each one ).
回答1:
gem fetch
So, something like $ gem fetch gosu ... this will leave gosu-0.7.14.gem in the current directory.
This will work even if you have already installed it.
回答2:
Most of the gems are hosted on github.com right now, you just have to clone the repo.

Yes it is. Browse to the package's page on RubyGems.org and follow the download link.
Eg. from https://rubygems.org/gems/pony to https://rubygems.org/downloads/pony-1.4.gem
