Hello, I'm using instantrails 2 to develop RubyOnRails projects on windows and need to update my ruby version to 1.8.7 (I'm still using 1.8.6). I downloaded ruby 1.8.7 here http://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.7.zip and unzipped files in the ruby folder of instantrails but when I check "ruby -v" I still got 1.8.6 (I tried a gem update and same thing, some gems won't update because they detect ruby 1.8.6 and not 1.8.7).
Any idea what I'm doing wrong??
You should check railsinstaller … or even better try to change to a linux distribution

The files you download are the source code, you'll have to compile it to have it available as a binary on your machine. Not sure how that squares with InstantRails, though. You might want to look at RailsInstaller from Engine Yard, which I gather is the latest thing for Windows + Rails. Someone else with experience using Posix software on Windows can probably point out my errors and what you should do.

Hello Javier and Walter,
First thanks for your reply. I already had a look at RailsInstaller but I would prefer not to change my development environment, just update ruby to 1.8.7...I'm gonna keep looking for a solution about that.
Olivier.
You can take a look at Pik gem, it works very similar to RVM with the difference that this works on windows =D
Here’s the URL: http://rubygems.org/gems/pik
I have done exactly what you describe and it did work. Did the files from the zip end up in the ruby/bin and ruby/lib folders? As this is Windows you probably should reboot if you havn't.
Reviewing I think I find I did something different. I downloaded binaries from http://ftp.ruby-lang.org/pub/ruby/binaries/mswin32/ruby-1.8.7-p330-i386-mswin32.zip and they worked fine. As someone said what you have downloaded is the source and you really do not need that.
Thank you all for the help, I used the binaries files you said (actually Walter was right from the beginning...) and it worked great!
