アイテムをインポートすると、私のスパイダーは無駄になりますか？

Question

私の問題は何らかの理由でスパイダーがフレームワークによって見つからないように見えることです。私はこのクモを得た：

import scrapy 
from scrapy.http import Request 
from propreties.items import htmltableitem 


class SymbolspiderSpider(scrapy.Spider): 
    name = "symbolspider" 

    def start_requests(self): 
     for i in range(0,10): 
      yield Request('https://www.google.com/finance?q=%27&restype=company&noIL=1&num=50&ei=VPBjWJHKK9S7U6_dmvgM&start='+str(i)) 

    def parse(self, response): 
     l=ItemLoader(item=htmltableitem(), response=response) 
     l.add_xpath('htmltable', ".//*[@id='gf-viewc']/div/div[2]/form/table/tbody/child::*") 
     return l.load_item() 

私がscrapy crawl symbolspider -o output.csvそれエラーを実行すると：

Traceback (most recent call last): 
    File "/usr/bin/scrapy", line 11, in <module> 
    sys.exit(execute()) 
    File "/usr/lib/python3.5/site-packages/scrapy/cmdline.py", line 142, in execute 
    _run_print_help(parser, _run_command, cmd, args, opts) 
    File "/usr/lib/python3.5/site-packages/scrapy/cmdline.py", line 88, in _run_print_help 
    func(*a, **kw) 
    File "/usr/lib/python3.5/site-packages/scrapy/cmdline.py", line 149, in _run_command 
    cmd.run(args, opts) 
    File "/usr/lib/python3.5/site-packages/scrapy/commands/crawl.py", line 57, in run 
    self.crawler_process.crawl(spname, **opts.spargs) 
    File "/usr/lib/python3.5/site-packages/scrapy/crawler.py", line 162, in crawl 
    crawler = self.create_crawler(crawler_or_spidercls) 
    File "/usr/lib/python3.5/site-packages/scrapy/crawler.py", line 190, in create_crawler 
    return self._create_crawler(crawler_or_spidercls) 
    File "/usr/lib/python3.5/site-packages/scrapy/crawler.py", line 194, in _create_crawler 
    spidercls = self.spider_loader.load(spidercls) 
    File "/usr/lib/python3.5/site-packages/scrapy/spiderloader.py", line 51, in load 
    raise KeyError("Spider not found: {}".format(spider_name)) 
KeyError: 'Spider not found: symbolspider' 

おかしい事は、私はラインfrom propreties.items import htmltableitemを削除すると、それは今クモを検出しているが、単なる事実のにエラーが生成さアイテム呼び出しが不明であることを示します。何が起こっている ？

Answer 1

それは

from googlefinance.items import htmltableitem 

ではなく

from propreties.items import htmltableitem 

する必要があります

最初に、propretiesという名前のScrapyプロジェクトを作成した後、ソースコードを変更せずにディレクトリをgooglefinanceに変更しました。

propretiesのすべてのエントリをコードに置き換え、scrapy.cfgの内容もチェックしてください。
