I've been following this lynda tutorial online on 'Ruby on Rails.' I've downloaded Ruby, devkit and rails on to my computer. After I created sample_app and tried to run bundle install, but it keeps telling me make sure that 'gem install json -v 1.8.2' succeeds before bundling" I try to run gem install json -v 1.8.2 and other variations including "gem install json -v 1.8.2 --verbose", "gem install json --platform=ruby" but everytime I get an error saying that it failed to build gem native extensions. The same thing happened when I was following the downloading devkit tutorial and I tried to install JSON as per its instructions. I've tried using gem update system 2.3.0 but that doesn't work either. What could be wrong?

Typically this will happen on Windows because not all the commands are availible. I would recommended that you either use VirtualBox with an Ubuntu image or use Cloud9 IDE.

I just experienced the same problem myself. I am working my way from Windows to a Mac but not quite there just yet. Windows is ok for Rails development (been doing so for 3 years) although it does present some unique issues occasionally. Check out the following link to downgrade RubyGems to 1.8.29 and then try running bundle install again.
