无法使用smarter_csv运行rake任务

我创建了一个rake任务，用于导入一个csv与smarter_csv gem。无法使用smarter_csv运行rake任务

抛出下面的消息，我加了整个的错误代码，如果有帮助：

rake import_csv:import_csv

(See full trace by running task with --trace)

这是rake任务代码：

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

这是整个堆栈跟踪？ – phoet

这只是解决了难熬点。路线问题。

./csv_imports/file.csv
