【问题】
在折腾：
期间，运行scrapy项目，结果出错：
E:\Dev_Root\python\Scrapy\manta\manta>scrapy crawl manta -o respBody -t json E:\Dev_Root\python\Scrapy\manta\manta> |
【解决过程】
1.后来发现，之前也遇到类似的错误：
而且已经解决了，但是此处的错误，不是之前的那种。
2.参考：
去看看mantaspider.py中的内容为：
from scrapy.contrib.spiders import CrawlSpider
from scrapy.selector import HtmlXPathSelector
from scrapy.crawler import CrawlerProcess
from scrapy.http import Request
import re
class spider(CrawlSpider):
name="mantaspider"
start_urls=["http://www.manta.com/mb_44_A0139_01/radio_television_and_publishers_advertising_representatives/alabama"]
def parse(self,response):
hxs=HtmlXPathSelector(response)
f=open("responsebody","w")
f.write(response.body)
f.close()
next_href_list=hxs.select("//a[@class='nextYes']/@href")
is_next=False
#print response.body
if len(next_href_list):
is_next=True
next_href=next_href_list[0].extract()
print "*****************************"
print next_href
print "*****************************"
Request(str(next_href),self.parse)
internal_page_urls_list=hxs.select("//a[@class='url']/@href")
for internal_page_url in internal_page_urls_list:
internal_page_url=internal_page_url.extract()
Request(str(internal_page_url),self.parse_internal)
def parse_internal(self,response):
try:
item=[]
item["title"]=hxs.select("//h1[@class='profile-company_name']/text()").extract()
print "*****************************"
print item
print "*****************************"
except:
print "All items not found here"所以，得知了crawler的名字是mantaspider，所以换个名字试试，结果至少就可以正常运行了：

【总结】
在运行Scrapy项目时，不是：
| scrapy crawl 文件夹名字 -o respBody -t json |
而是：
先找到，形如xxxxSpider.py的文件，其中有类似于：
class spider(xxxxSpider): name="yourRealNameSipder"
的代码，其中的yourRealNameSipder，才是爬虫的名字，然后运行：
scrapy crawl yourRealNameSipder -o respBody -t json
才可以。
