Question

我创建了一个rake任务，用于导入带有 smarter_csv gem的csv。

抛出以下消息，如果有帮助，我添加了整个错误代码：

rake import_csv:import_csv

Tasks: TOP => import_csv:import_csv
(See full trace by running task with --trace)

这是rake任务的代码：

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

这解决了一点点。路线问题。

 ./csv_imports/file.csv

无法使用smarter_csv运行rake任务
