Installing gems for a single user

ruby-talk
1

I'm used to using gems locally where I can install them systemwide. But
in a shared hosting environment, where there might be several systemwide
gems installed by the host, there may be gems I want to install just in
my home directory. Does RubyGems support this? In a way that your Ruby
program can access both the systemwide and local gems?

Thanks!

Sure:

  mkdir ~/.gems
  export GEM_HOME=/home/jennyw/.gems
  wget http://code.whytheluckystiff.net/sources/rubyforge-0.0.1.gem
  gem install rubyforge-0.0.1.gem

And you should be able to `gem list`, `gem install`, etc.
  
In scripts where you don't have control over the environment and RubyGems is
already loaded, use:

  Gem.use_paths("/home/jennyw/.gems")

For other concrete examples, you might scan:

My solution: compile and install Ruby in ~/software (or similar) and
use *that* Ruby for everything, including gems. No permission
problems.
