Now this is my first question here. I’m trying to install Ruby On Rails

  • 0

Now this is my first question here. I’m trying to install Ruby On Rails for the first time on my Macbook, following this guide: http://hivelogic.com/articles/compiling-ruby-rubygems-and-rails-on-snow-leopard/

I think, Ruby and RubyGems are set up correctly, but when I call the "sudo gem install rails"-command, the terminal sends back the following warnings and errors:

WARNING: Installing to ~/.gem since /usr/local/lib/ruby/gems/1.8 and /usr/local/bin aren’t both writable.

WARNING: You don’t have /Users/benjaminkowalski/.gem/ruby/1.8/bin in your PATH, gem executables will not run.

ERROR: Error installing rails: rdoc requires json (~> 1.4, runtime)

Since I’m no expert with the terminal – what should I do next? Google and Stackoverflow don’t tell..

    That error comes from using an older version of Ruby to install the current version of Rails.

    The tutorial you are using had you install Ruby 1.8.7. I don’t know offhand if Ruby 1.8.7 will install Rails 3.1.1 (current as of this post). I’d recommend trying to install Ruby 1.9.2 and then using it to install Rails 3.1.1.

    To make this Ruby version thing easier, I’d highly recommend trying RVM. Its dead simple and incredibly useful for maintaining and using multiple versions of Ruby concurrently.
