Question

我有两只蜘蛛，它们都有相同的名字（错误的是人类）。

class ProductSpider(scrapy.Spider):
    name = 'Product'

当我爬行时，两只蜘蛛都爬了。

所以，当我更改其中一个蜘蛛的名称（另一个蜘蛛仍然具有相同的名称Product）时：

scrapy crawl Product

我收到以下错误：

Traceback (most recent call last):
  File "/usr/local/bin/scrapy", line 11, in <module>
    sys.exit(execute())
  File "/Library/Python/2.7/site-packages/scrapy/cmdline.py", line 143, in execute
    _run_print_help(parser, _run_command, cmd, args, opts)

    cmd.run(args, opts)

    self.crawler_process.crawl(spname, **opts.spargs)
  File "/Library/Python/2.7/site-packages/scrapy/crawler.py", line 150, in crawl
    crawler = self._create_crawler(crawler_or_spidercls)
  File "/Library/Python/2.7/site-packages/scrapy/crawler.py", line 165, in _create_crawler
    spidercls = self.spider_loader.load(spidercls)
  File "/Library/Python/2.7/site-packages/scrapy/spiderloader.py", line 40, in load
    raise KeyError("Spider not found: {}".format(spider_name))
KeyError: 'Spider not found: Product'

但是，在调试时，当我将名称Product更改为随机的新名称foo时，它可以正常工作。

我不明白。为什么会这样？

KeyError：未找到蜘蛛[Scrapy]
