Since Windows doesn't support rvm (Ruby version Manager), how do we have
on the same PC? Virtual machines can be used but it is kind of troublesome.

These allow you to keep multiple versions of Ruby on the same system. Once you've installed a version manager, and installed your own Ruby version, you won't mess with your system's Ruby and its Gems, which is the greatest benefit. No more sudo !
There's nothing you need to do to manage two different Rails versions. The only thing you'll want to do is gem install rails to get the latest version and create your new project with rails new myapp . That will make sure the new project starts with Rails 5.1 (or whatever is the latest at the time).
Use uru. It is a multi-platform ruby environment manager. You can download the Windows version here: https://bitbucket.org/jonforums/uru/wiki/Downloads
Install the tool
Assuming C:\tools is on PATH and uru_rt.exe was extracted to C:\tools
C:\tools>uru_rt admin install This adds uru.bat file to the tools directory.
Register ruby
uru admin add C:\ruby200\bin List available rubies
uru ls 174 : jruby 1.7.4 (1.9.3p392) 2013-05-16 2390d3b on Java HotSpot(TM) 200p255 : ruby 2.0.0p255 (2013-07-07 revision 41812) [i686-linux] => system : ruby 2.1.0dev (2013-07-06 trunk 41808) [i686-linux] Switch ruby version
uru 174 ---> Now using jruby 1.7.4 tagged as `174` More commands can be found here: https://bitbucket.org/jonforums/uru/wiki/Examples
I use Pik to manage multiple versions of ruby on a Windows machine.
Install the pik gem
> gem install pik Successfully installed pik-0.2.6 1 gem installed Install pik to a location that’s in your path, but someplace other than your ruby\bin dir.
>echo %path% PATH=c:\pik;c:\ruby\Ruby187\bin; >pik_install C:\pik Thank you for using pik. Installing to C:\pik pik is installed Install Ruby 1.9.2 using RubyInstaller and add the new Ruby version to pik registry.
>pik add C:\Ruby192\bin List the available Ruby versions:
>pik list 187: ruby 1.8.7 (2010-01-10 patchlevel 249) [i386-mingw32] * 192: ruby 1.9.2p0 (2010-08-18) [i386-mingw32] To switch to Ruby 1.9.2:

In Rails 2.x, set the RAILS_GEM_VERSION in config/environment.rb file:
RAILS_GEM_VERSION = '= 2.3.8' unless defined? RAILS_GEM_VERSION In rails 3, use the Gemfile to specify the Rails version:
gem "rails", "3.0.0" If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
