What is Ruby 1.9 standard CSV library? <p>When I try the FasterCSV gem on my application I get this error:</p> <pre><code>Please switch to Ruby 1.9's standard CSV library. It's FasterCSV plus support for Ruby 1.9's m17n encoding engine. </code></pre> <p>By the way, I'm using Rails 3, Ruby 1.9.2, and Rubygems 1.4.</p> <p>Can someone explain to me please how to use the standard CSV library for Ruby 1.9. I don't have any idea at all because I'm very new to Rails.</p>
