无法理解这是什么问题
nameTag = "div[class='designer_about'] a"
designsTag = "li[class='span-2']"
pullTags = Array.new(nameTag, designsTag)
错误:
designers_list_mirraw.rb:8:in `initialize': can't convert String into Integer (TypeError)
from designers_list_mirraw.rb:8:in `new'
from designers_list_mirraw.rb:8:in `<main>'
