*nix is much better for development in general, and those who disagree are just plain wrong (in my supreme opinion). Still, sometimes we are forced to work on Windows (someone from “above” orders such an unspeakable thing, and the others, lesser human beings are oblidged to comply).
Download: Ruby Installer Downloads
Install Ruby somewhere in under C:\, like C:\Ruby25-x64, and make sure to check the option that adds Ruby executables to your path, and also check the option to associate .rb files with the Ruby installation.
Here for the deprecated < 2.4: Ruby DevKit < 2.4
Install it under <Path-To-Your-Ruby-Install-Div\devkit, something like:
C:\Ruby25-x64\devkit
With the command line, navigate to that directory and run:
ruby dk.rb init
Then open C:\Ruby25-x64\devkit\config.yml and add the line:
- C:/Ruby25-x64
Note that we used a forward slash “/” in this specific case, not the windows style backslash “\”.
Then run:
ruby dk.rb install
And we also need setup the gem sources. For this company, we need to remove the “https” url because the firewall is blocking it for some reason… and… add only the “http” one.
gem sources --add http://rubygems.org gem sources --remove https://rubygems.org gem sources --clear gem sources --update
If you don’t understand those commands, try reading:
gem sources --help
