If the file wasn’t found, it iterates over the next directories until the file is found. When you type “ ruby” command, your shell tries to find the file in the first directory. /usr/bin (where “ ruby” is actually located).So $PATH variable has multiple directories, separated by “ :” (colon): usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin Debugging Example - Save the World with Ruby.The truth about Object-Oriented programming.
Arrays of Arrays (two-dimensional arrays in Ruby).Strings, Data Types and Objects in Ruby.For example, gem developers can consult information on DLL loading, MSYS2 library dependency, path separator, and shell escaping.

Running the setup file again will remove RubyInstaller from your computer.
This is required for setting up gems with C extensions. Toward the end of setup, you can instruct the utility to run "ridk install" in order to install the MSYS2 and development toolchain. In addition to the Ruby environment, the downloaded package includes a necessary set of RubyGems and extensions, making it possible to integrate the tool with MSYS2 installations. It's a Ruby language execution environment for Windows users, which comes wrapped in an installer and portable edition, ready to help you write code in Ruby and deploy applications immediately. If you're interested in the Ruby programming language, you can easily install all the necessary tools with RubyInstaller.
