I am kinda new to ruby and new to ruby on rails. I originally had 1.9.1 installed but that caused errors when trying to install gems and compile them. I then installed 1.8.6 and then that has errors when trying to use postgresql. What version is the best to install on a windows machine where gems install and work and databases seem to work correctly? I am running Windows 7. Is there a huge difference between 1.9.1 and 1.8.7 and 1.8.6? Its kinda confusing for a person new to rails and ruby. I am still teaching myself ruby so maybe i should just grab the best version for that then worry about rails. Thanks, --Nick
