Stuck installing Rails: rails s and bundle exec rails server error

Question

I am using Windows 7, Ruby 2.2.1, and Rails 4.2.0. I get the following error after running rails s or bundle exec rails server:

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!

You will have to install the correct dll for nokogiri. When i first started i used windows for about 6 months before moving to linux for ruby development. It is noticeably faster and you don't run into as much weirdness as in windows. I recommend installing a virtual machine with ubuntu 14.04 on it. — Austio, Mar 09 '15 at 02:07
I may just find an old HDD somewhere install Ubuntu onto it. looks like windows isn't the way to go. — David Czerepak, Mar 09 '15 at 02:48
You will save yourself alot of heartache. I experience a lot of pain before i spent the time to switch and wish i had not waited that long. — Austio, Mar 09 '15 at 12:47

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.

I'm pretty much installing to learn Ruby. I'm going to try and older version for Ruby, but if its the Gems I don't see how I will get around this. It seems its not just nokogiri. — David Czerepak, Mar 09 '15 at 02:51

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.
