I have Win 7 Pro. I have upgraded from Ruby 1.9.3 to 2.1.3, and the correct DevKit.
I now have problems with my Watir automated testing. In order to blame/absolve Ruby, I need to revert to Ruby 1.9.3 and the correct DevKit.
Is there an easy way to revert without deleting my current Ruby and Devkit?
I'm not a techie, but I think I can have two versions of Ruby in different folders simply by modifying the "Path" in Control Panel.
How would I maintain two versions of DevKit?
Further info: I do not use Rails.
you can temporary change the ruby in unix machine, try it in windows:
rvm list
will output something like this:
rvm rubies
ruby-1.8.7-p371 [ i686 ]
ruby-1.8.7-p374 [ i686 ]
ruby-1.9.3-p327 [ x86_64 ]
* ruby-1.9.3-p392 [ x86_64 ]
ruby-1.9.3-p484 [ x86_64 ]
ruby-2.0.0-p247 [ x86_64 ]
ruby-2.1.1 [ x86_64 ]
=> ruby-2.1.2 [ x86_64 ]
# => - current
# =* - current && default
# * - default
as you see, my current ruby is 2.1.2, you can change it by typing
rvm use ruby-1.9.3-p484
