意外“：”和意外“）”错误

Question

我的红宝石版本中运行下面的代码1.8.7

require 'csv' 

FILENAME = 'filename' 

cleansed_output = File.open('filename_cleaned.csv','wb') 

CSV.open(FILENAME, encoding: 'ISO8859-1') do |output| 
    row_number = 1 
    loop do 
    begin 
     break unless row = output.shift 
     cleansed_output << row.to_csv 
    rescue CSV::MalformedCSVError => e 
     puts "Malformed row #: #{row_number}" 
    ensure 
     puts "Row number: #{row_number}" if row_number % 10000 == 0 
     row_number += 1 
    end 
    end 
end 

cleansed_output.close 

和我得到了以下错误：

csv_cleanser2.rb:7: syntax error, unexpected ':', expecting ')' 
CSV.open(FILENAME, encoding: 'ISO8859-1') do |output| 
          ^
csv_cleanser2.rb:7: syntax error, unexpected ')', expecting $end 
CSV.open(FILENAME, encoding: 'ISO8859-1') do |output| 

我试图用分隔符来清理csv。任何人都知道问题在这里？

谢谢！

你使用Ruby 1.8.7，但你要使用1.9哈希语法：

CSV.open(FILENAME, encoding: 'ISO8859-1') do |output| 

尝试使用旧校舍哈希火箭：

CSV.open(FILENAME, :encoding => 'ISO8859-1') do |output|
