Assuming you are working your way through the tutorial at

http://doc.scrapy.org/en/latest/intro/tutorial.html#our-first-spider

you probably forgot to import the BaseSpider class with

from scrapy.spider import BaseSpider

as shown in the code snippet in the "Our first Spider" section of the
tutorial.
