# Ruby Application: Ruby Also called rubyinstaller, ruby installer, mri ruby Ruby, Productivity The Ruby language on Windows. RubyInstaller is the usual path. The process is ruby.exe. It is not Python. ## What you need to know Ruby on Windows is usually RubyInstaller. It is not Python. ruby.exe is MRI. RubyInstaller is the usual Windows build. python.exe is a different language. - **What is it?**: Language runtime **Still current?**: Yes, see Current status **Official download?**: Use the vendor link in this article Feex says If gem install fails on a native extension, I run ridk install from RubyInstaller. I do not pip install that gem, and I do not switch to python.exe. ## What is Ruby? ruby.exe is MRI Ruby. RubyInstaller wraps it for Windows. Python is python.exe. Gems are not pip. ## If you have never used it If you need Ruby on Windows, use RubyInstaller from rubyinstaller.org, then ridk to get MSYS2 build tools when gems need them. python.org is a different language. Rails tutorials that say "install Ruby" mean this runtime, not Python. ## What is it used for? **Run .rb scripts and irb** ruby.exe. python.exe will not run that file. **gem install** RubyGems. Native gems need ridk / MSYS2 from RubyInstaller, not a Python venv. **Rails and other frameworks** Those sit on this runtime. A Node or Python stack is a different tutorial. ## Who is it for? - People following a Rails on Windows guide - Anyone who typed ruby and got nothing - Users who almost installed Python for a .rb file ## Current status Ruby (1995) is a current language runtime from Ruby. The vendor still points Windows users at https://rubyinstaller.org/. ## How old is it? Ruby dates to 1995. RubyInstaller has been the practical Windows path for years. The old RailsInstaller brand is stale. Python is a sibling language, not a Ruby build. ## Versions Major channels first. Exact build numbers are not all verified here. RubyInstaller 3.x Ruby+Devkit ## System requirements Values follow the publisher's public guidance. Workload still changes the real need. ### Minimum | Operating system | A current supported Windows 10 or Windows 11 release, per the vendor | | ---------------- | -------------------------------------------------------------------- | | RAM | Enough for Windows plus this app. Heavy projects want more. | ## Resource profile - **CPU demand**: Follows what you open inside the app **RAM demand**: Follows documents, tabs, or libraries ## Installed processes These executables belong to this product when it is installed. | ruby.exe | Main Windows executable | | -------- | ------------------------------------ | | ridk.cmd | MSYS2 helper RubyInstaller documents | ## Startup components ruby.exe does not start with Windows unless a script in Startup calls it. ## File locations | Typical install | C:\Ruby3x-x64\\ | | --------------- | --------------- | ## File formats RB, GEMFILE ## Common problems ### Installed Python because the homework said "a scripting language" A .rb file needs ruby.exe. Python will not parse it. ### Native gem failed without MSYS2 RubyInstaller's ridk is the documented fix. That is not a Laragon issue. ## Getting unstuck ### Install from rubyinstaller.org (Ruby+Devkit if you will compile gems) ruby-lang.org documents the language. The Windows bits are RubyInstaller. ### ridk install when a gem needs a compiler MSYS2 toolchain. Visual C++ redist is a different runtime some gems still mention. ### where.exe ruby if the Store or another ruby.exe stole PATH Confirm Program Files\Ruby3x, not a random Downloads copy. ## Alternatives WSL Ubuntu plus apt ruby is another Windows path. Python and PHP are other languages. Laragon can add Ruby, but RubyInstaller is the usual standalone. ## Official help and downloads Start with the vendor.
