我从一个旧系统导出了一些粗糙的 mySQL CSV，我正在解析并加载到一个新的 Ruby on Rails 应用程序中。
下面是一个例子：
"1","1","When a ticket is marked as Resolved, revert the assigned_to to the one who started it",,"7","1","1.00","0.00","2",NULL,NULL,"1","2009-06-04 16:40:37","2009-06-04 16:40:37",NULL,"0000-00-00 00:00:00";"2","2","Email notifications when ticket is assigned to someone",,"1","1","1.00","0.00","1",NULL,NULL,"1","2009-06-04 16:41:21","2009-06-04 16:41:21",NULL,"0000-00-00 00:00:00";"3","1","When a ticket is marked as Resolved, revert the assigned_to to the one who started it - and notify",,"7","1","1.00","0.00","2",NULL,NULL,"1","2009-06-09 18:10:47","2009-06-09 18:10:47",NULL,"0000-00-00 00:00:00";"4","3","Change Password Capability","Fix the forgot password capability (and for bonus points, add capability for user to change once logged in.","7","1","0.00","0.00","1",NULL,NULL,"9","2009-06-09 18:13:45","2009-06-09 18:13:45",NULL,"0000-00-00 00:00:00";"5","4","Manager View","Don't need listed:

Status

字段用双引号括起来，以逗号结尾，行以分号结尾。正如您所希望看到的，在特定领域内有硬回报（？）。这就是它们在 CSV 文件中的显示方式，而不是换行符。
我用于解析 CSV 的 ruby 测试代码：
csv_file_path1 = 'data/file.csv'
CSV.foreach( csv_file_path2, { :row_sep => ";" } ) do |row|
puts row[1]
end
当我通过 rake 任务运行它时，我得到输出：
1
2
3
4
5
6
7
8
rake aborted!
Missing or stray quote in line 9
...
为什么它不能解析该字段中具有硬返回的行？谢谢。
编辑：更新以显示更多 CSV。
