1) Following regex in ruby is throwing server start (compile) time error on Mac Book Pro while on Ubuntu it is working.
    # Clean all new line character
    string.gsub!(/(?<!\n)\n(?!\n)/, '')

   Error :
    undefined (?...) sequence: /(?<!\n)\n(?!\n)/ (SyntaxError)
   
   Solution :
   string.gsub!(/\r/,"")
   string.gsub!(/\n/," ")
