Scrapy traceback错误(无效语法)

Question

我已经关注了几个教程，并且不断地获得SyntaxError：

C:\Users\Luis\mercado>scrapy crawl mercado -t csv
Traceback (most recent call last):
  File "C:\Users\Luis\Anaconda2\Scripts\scrapy-script.py", line 5, in 
<module>
    sys.exit(scrapy.cmdline.execute())
  File "C:\Users\Luis\Anaconda2\lib\site-packages\scrapy\cmdline.py", line 
149,
in execute
    cmd.crawler_process = CrawlerProcess(settings)
  File "C:\Users\Luis\Anaconda2\lib\site-packages\scrapy\crawler.py", line

    super(CrawlerProcess, self).__init__(settings)
  File "C:\Users\Luis\Anaconda2\lib\site-packages\scrapy\crawler.py", line

line 47, in _load_all_spiders
   for module in walk_modules(name):
  File "C:\Users\Luis\Anaconda2\lib\site-packages\scrapy\utils\misc.py", 
line 71
, in walk_modules
    submod = import_module(fullpath)
  File "C:\Users\Luis\Anaconda2\lib\importlib\__init__.py", line 37, in 
import_module
    __import__(name)
      File "C:\Users\Luis\mercado\mercado\spiders\spider.py",     line 7
            Class MercadoSpider(CrawlSpider):
SyntaxError: invalid syntax

你能帮我拿一下吗？

在Python中，class总是以小写形式编写。您的Python中存在语法错误。
