如何在ruby 1.8.7中读取CSV？

Question

I just want to read a csv file and discard the header row.

When I do csv = CSV.read('file_name.csv','r') I get

.rvm/rubies/ruby-1.8.7-head/lib/ruby/1.8/csv.rb:98:in `read': can't convert String into Integer (TypeError)

When I do

csv = CSV.open('file_name.csv','r')
csv.shift

I get

.rvm/rubies/ruby-1.8.7-head/lib/ruby/1.8/csv.rb:639:in `get_row': CSV::IllegalFormatError (CSV::IllegalFormatError) from .rvm/rubies/ruby-1.8.7-head/lib/ruby/1.8/csv.rb:567:in `shift'

What is an example of successfully reading csv files and manipulating data in ruby 1.8.7?

Answer 1

Do it like this:

csv = CSV.read('file_name.csv')

"r" is not a correct parameter for CSV.read

Answer 2

The file line endings was the issue. I changed all of them to unix's LF.
