Rails 3 Server Startup problem with fastercsv

Question

I have a rails 2.3.5 app getting upgraded to Rails 3. I did every thing I am required to do for upgrading and when I start the rails server using

rails server

it gives me this

Please switch to Ruby 1.9's standard CSV library.  It's FasterCSV plus
support for Ruby 1.9's m17n encoding engine.

I am using ruby-1.9.2-p0 and have fastercsv (1.5.3) gem installed. with the help of puts statements, i was able to track down where the error occurred. i found that the execution stops at this line

Bundler.require(:default, Rails.env) if defined?(Bundler)

in application.rb file. I tried many things but none worked .. please help..

Answer 1

Remove fasterCSV from your Gemfile in the application. Bundler is trying to require FasterCSV because you have it specified in the Gemfile.

Answer 2

with 1.9 you no longer need/can use the fastercsv gem, since it's bundled in the std lib. Now you just need to do:

require 'csv'
CSV.open("temp.csv", "w") do |csv|
  csv << ["line1row1", "line1row2"]
  csv << ["line2row1", "line2row2"]
  # ...
end
