无法使用smarter_csv运行rake任务

Question

I created a rake task for import a csv with smarter_csv gem.

Throws the following message, i added the entire error code if it helps:

rake import_csv:import_csv

This is the code on the rake task:

namespace :import_csv do
  desc "import csv file"
  task import_csv: :environment do
    require 'smarter_csv'
    filename = '/csv_imports/file.csv'
    options = {:key_mapping => { :downcase_header => true }}
    SmarterCSV.process(filename, options) do |array|
      CsvImports.create( array.first )
    end
  end

end
