Unable to run Scrapy code - django

Question

I have written the following code:
spiders.test.py code:
from scrapy.spider import BaseSpider
from scrapy.selector import HtmlXPathSelector
from wscraper.items import WscraperItem
class MySpider(BaseSpider):
name = "ExampleSpider"
allowed_domains = ["timeanddate.com"]
start_urls = ["https://www.timeanddate.com/worldclock/"]
def parse(self, response):
hxs = HtmlXPathSelector(response)
titles = hxs.select("/html/body/div[1]/div[8]/section[2]/div[1]/table/tbody").extract()
#for titles in titles:
#title = titles.select("a/text()").extract()
#link = titles.select("a/#href").extract()
print title
The code for scraper.items is:
from scrapy.item import Item, Field
class WscraperItem(Item):
# define the fields for your item here like:
# name = scrapy.Field()
title = Field()
pass
I'm getting the following error on running the command "scrapy crawl ExampleSpider":

Answer 1

Spider name has to be str, not list, so:
class ExampleSpider(BaseSpider):
name = "timeandzone"
otherwise Scrapy spider loader fails to load it.

Answer 2

Basically, I had a compatibility issue.So, I installed Scrapy1.3.3 and this resolved the issue and yes as mentioned in the answer above spider name should be a string.
