치료 자습서 : 치료 크롤링을 실행할 수 없습니다. dmoz

Question

마지막 질문에서 충분히 명확하지 않다는 것을 알고 있기 때문에 새로운 질문을하고 있습니다. 나는 자습서를 따르려고 노력하고 있지만 중요한 단계 인 "scrap crawl dmoz"명령에 붙어 있습니다. 코드는이 코드입니다 (파이썬 셸에서 작성한 내용이며 .py 확장) :

ActivePython 2.7.2.5 (ActiveState Software Inc.) based on 
Python 2.7.2 (default, Jun 24 2011, 12:20:15) 
[GCC 4.2.1 (Apple Inc. build 5664)] on darwin 
Type "copyright", "credits" or "license()" for more information. 
>>> from scrapy.spider import BaseSpider 

class dmoz(BaseSpider): 
    name = "dmoz" 
    allowed_domains = ["dmoz.org"] 
    start_urls = [ 
     "http://www.dmoz.org/Computers/Programming/Languages/Python/Books/", 
     "http://www.dmoz.org/Computers/Programming/Languages/Python/Resources/" 
    ] 

    def parse(self, response): 
     filename = response.url.split("/")[-2] 
     open(filename, 'wb').write(response.body) 

>>> 

내가 괜찮을 사용하고 디렉토리 트리를 검색 :

을 지금은 "scapy 크롤링 DMOZ"나는이 얻을 실행하려고하면

$ scrapy crawl dmoz

아무도 내가 밟고있는 단계가 무엇인지 잘못 알고 있습니까? 도움 주셔서 감사합니다. 이것은 제 첫 번째 프로그래밍 경험이므로 매우 어리석은 문제 일 수 있습니다.

Answer 1

들여 쓰기가 올바르지 않습니다. 그것은해야한다 :

>>>from scrapy.spider import BaseSpider 

>>>class dmoz(BaseSpider): 
     name = "dmoz" 
     allowed_domains = ["dmoz.org"] 
     start_urls = [ 
      "http://www.dmoz.org/Computers/Programming/Languages/Python/Books/", 
      "http://www.dmoz.org/Computers/Programming/Languages/Python/Resources/" 
     ] 

     def parse(self, response): 
      filename = response.url.split("/")[-2] 
      open(filename, 'wb').write(response.body) 

난 당신이 IDLE의 코드를 붙여 복사 생각하십시오 들여 쓰기 클래스입니다.

Answer 2

그것은 들여 쓰기 문제가 아니에요, 오류 메시지는 분명하다 :

File "/Users//Documents/tutorial/tutorial/spiders/dmoz_spider.py", line 1 
ActivePython 2.7.2.5 (ActiveState Software Inc.) based on 
      ^
SyntaxError: invalid syntax 

당신은 명확 사본이 더 코드없는 유휴에서 시작하는 문자열을 포함 IDLE의 코드를 붙여 있습니다.

복사 붙여 넣기 대신 편집기를 열고 실제 튜토리얼 코드를 입력하면 더 잘 배우고 실수로 붙여 넣기하지 않을 것입니다.
