\*Hi,

Re upgrading to the latest version of Ruby is there a command line /  
gems  
type upgrade approach, or do I need to download the “\*Ruby 1.8.5  
One-Click  
Installer  
[http://rubyforge.org/frs/download.php/12751/ruby185-21.exe](http://rubyforge.org/frs/download.php/12751/ruby185-21.exe)Stable  
version (  
_recommended_)” and use this to update my windows install?

Thanks

then I  
guess?

I don’t think anything like that exists. There was a thread sometimes  
ago about preserving installed gems across installation (I don’t  
remember what they did come to).

Just be aware that it will probably wipe out anything in your ruby  
directory, including gems and anything else, last I heard.
