I have a CSV file that contains blank rows like this:
row A
row B
row C
row D
How should I proceed to remove those blank rows to have:
row A
row B
row C
row D
I found many topics on this subject for other languages but none in Ruby.

Three simple steps:
data = File.read('data.csv') # Read the file
cleaned = data.gsub(/^$n/, '') # Remove blank lines, from [1]
File.open('out.csv', 'w') # Write the cleaned data
[1] Remove empty lines from string

You don't have to delete the blank lines, just skip them:
require "csv"
CSV.foreach("path/to/file.csv", skip_blanks: true) do |row|
# handle row, it won't be blank
end
