I have 1.9.1 installed (from zip). My scripts use the win32-service gem, so installed it with: > gem install win32-service This installed the following gems without error: win32-api (1.4.0) win32-service (0.6.1) windows-api (0.3.0) windows-pr (1.0.3) When I run the script, I get this in a pop-up dialog: “This application has failed to start because msvcrt-ruby18.dll was not found.” And the first line of console error is: C:/ruby/lib/ruby/gems/1.9.1/gems/windows-api-0.3.0/lib/windows/api.rb:1:in `require’: 126: The specified module could not be found. - C:/ruby/lib/ruby/gems/1.9.1/gems/win32-api-1.4.0-x86-mswin32-60/lib/win32/api.so (LoadError) I _think_ that means that one or more of those gems are compiled against the older Ruby. I’m a gems n00b. Does gems not check for this mismatch of ruby versions? How can I get these gems for Ruby 1.9.1? Thanks for any help. -Grant ---

I’ve exposed the same concern here: [http://rubyforge.org/pipermail/rubygems-developers/2009-April/004522.html](http://rubyforge.org/pipermail/rubygems-developers/2009-April/004522.html) Cleverly enough, Aaron P. just blogged on how to overcome this issue, at least form the gem developer perspective: [http://tenderlovemaking.com/2009/05/07/fat-binary-gems-make-the-rockin-world-go-round/](http://tenderlovemaking.com/2009/05/07/fat-binary-gems-make-the-rockin-world-go-round/) I’m going to work with him on improve this mechanism so gem developers can distribute binary gems painlessly at RubyForge. If someone works on a series of patches for RubyGems, that can help too 😉 Regards, ---

For my immediate needs, does that mean I’m should give up and go back to 1.8 for now? I don’t expect every gem to be rebuilt, but I’m guessing that mswin32-api and windows-api are pretty crucial to any ruby/Windows work. I guess I’d expect that someone would have built 1.9.1 versions of these by now, but Google is not finding any for me. -Grant ---

Looks like you’ll either have to try and compile them from source (conceivably possible, if you’ve installed the devkit [1]) or downgrade.

I ran “gem --remote list” and I didn’t see a 1.9.1 version of the gems, so I assume there isn’t one. I ended up just downgrading to the newest 1.8 release. Seems to be working fine. ---
