无法使用smarter_csv运行rake任务
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 Digest::Digest is deprecated; use Digest I, [2017-03-01T11:46:08.551994 #7029] INFO -- : ** [Raven] Raven 0.14.0 configured not to send errors. rake aborted!

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
这解决了点。 路线问题。
./csv_imports/file.csv
