I’m having problems starting my Rails web server. I try to enter “rails server” in the cmd prompt but I get the following error:

C:\Ruby193\demo>rails server
←[31mCould not find gem 'jquery-rails (>= 0) x86-mingw32' in the gems available
on this machine.←[0m
←[33mRun `bundle install` to install missing gems.←[0m

but whenever I then do a bundle install to install the missing gem, I get this error:

C:\Ruby193\demo>bundle install

An error occured while installing json (1.6.6), and Bundler cannot continue.
Make sure that `gem install json -v '1.6.6'` succeeds before bundling.

I then tried to install json without any luck. Any suggestions?
