By default, Bundler installs gems into a shared location, but they can also be installed directly into your application. Once this specification is in place, Bundler installs all required gems (including the full gem dependency tree) and logs the results for later inspection. See the section below on using bundler.īundler allows you to specify which gems your application depends upon, and optionally which version those gems should be. This flag can be set as default by replacing -user-install by -no-user-install in /etc/gemrc (system-wide) or ~/.gemrc (per-user, overrides system-wide).īundler solves these problems to some extent by packaging gems into your application. Gems can be installed system wide by running the gem command as root, appended with the -no-user-install flag. Note: This can be made the default option by configuring the following ~/.gemrc file: This is required for executable gems to work without typing out the full location, although libraries will work without having to modify your path. ~/.profile export GEM_HOME="$(ruby -e 'puts Gem.user_dir')" The recommended way to setup that is by manually specifying your $GEM_HOME, which then can be appended to your $PATH environment variable in order to allow RubyGems binaries to be executed: This is considered the best way to manage gems on Arch, because otherwise they might interfere with gems installed by Pacman. It can be installed with the rubygems package, which is a dependency of ruby.īy default in Arch Linux, when running gem, gems are installed per-user (into ~/.local/share/gem/ruby/), instead of system-wide (into /usr/lib/ruby/gems/). Somewhat comparable to what pacman is to Arch Linux. RubyGems is a package manager for Ruby modules (called gems), The Java implementation of Ruby, JRuby can be installed with the jruby package.
You can then query the docs with: ri Array, ri Array.pop etc.
Install ruby-rdoc and ruby-docs for the documentation itself. To make documentation available through the ri command-line tool, The easiest way is to use one of RVM, chruby AUR, rbenv, asdf-vm AUR. If you want to run multiple versions on the same system (e.g. To install IRB, install the ruby-irb package. Ruby is a dynamic, interpreted, open source programming language with a focus on simplicity and productivity.įor the latest version of Ruby, install the ruby package.
