I’ve been working with Ruby professionally for over 3 years now and
I’ve grown frustrated with two of its most popular development tools:
RVM and Bundler. For those that may not know, RVM is the Ruby version
manager and it allows unprivileged users to download, compile,
install, and manage many versions of Ruby instead of being stuck with
the one that is installed globally by your distro’s package manager.
Bundler is the tool that allows developers to keep a version
controlled “Gemfile” that specifies all of the project’s dependencies
and provides utilities to install and update those gems. These tools
are crucial because Ruby developers often work with many applications
that use different versions of Ruby and/or different versions of gems
such as Rails. Traditional GNU/Linux distributions install packages
to the global /usr
directory, limiting users to a single version of
Ruby and associated gems, if they are packaged at all. Traditional
package management fails to meet the needs of a lot of users, so many
niche package managers have been developed to supplement them.
