I have also run gem list , and these gems are installed. Is it an issue with certain gem versions?

Also, it's 64-bit Windows; could it be in issue with that? I installed the 32 bit, so it should be compatible, right? I will try to uninstall and re-install everything with the 64-bit version of the DevKit and Ruby.

Thanks!

Answer 1

I had a very similar issue just today. I tried to do a new installation of ruby and rails today and I couldn't get "rails server" to work for the exact same reason.

In order to get this to work, you need to run gem install nokogiri --platform="ruby" but this fails on Windows because nokogiri doesn't compile properly on Windows.

It's supposed to work with the pre-compiled binary installation that RubyGems pulls down, but I think there's a bug somewhere in RubyGems or nokogiri that's causing this to not work right now, but I'm not sure.

Answer 2

Yeah, so I rolled back to 2.0.0. and it worked. You get "DL is deprecated, please use Fiddle" which I found here, Ruby 2.0.0p0 IRB warning: "DL is deprecated, please use Fiddle" , is just a warning. Still switching to Ubuntu soon.
