Package Management – Install Packages Through apt-get or gem?

aptitudegemrubyruby-on-railsUbuntu

If a package is available both through apt-get and gem, which one should I choose?

I'm on Ubuntu and I don't know if I should install rake through apt-get or gem.

I use both apt-get and gem packages a lot.

What are the pros and cons with each?

You should always use RubyGems to install any kind of Gems (eg. Rails) to reduce confusion.

Ruby on Rails: gem install versus apt-get

I installed rvm, I still don't know why there was such a mess but now I can just force a certain ruby version easily, and I know where all the gems get installed into. (into the rvm directory) Works for me.

The simplest way to download a gem without installing rubygems

To download a single gem use (using loudmouth gem as an example):

gem fetch loudmouth
Fetching: loudmouth-0.2.4.gem (100%)
Downloaded loudmouth-0.2.4

to download all gems that your Rails 3 app depends on run:

bundle package

This will download all gems (and their dependencies) and place them into vendor/cache (without installing them).

You can then burn all the gems in vendor/cache to a CD and physically bring it to the other server without net access.
