求助：为毛我的scrapy程序无法运行，实在查不出问题

行走的小布鞋

我写了个简单的scrapy程序，用于爬取网上的一些内容，代码如下：
items.py

1. from scrapy.item import Item, Field
   
2. 
   
3. class DmozItem(Item):
   
4. 
   
5.     title = Field()
   
6.     link = Field()
   
7.     comment = Field()

复制代码

dmoz.py如下：

1. from scrapy.spiders import Spider
   
2. from scrapy.selector import Selector
   
3. 
   
4. from dmoz.items import DmozItem
   
5. 
   
6. class dmoz(Spider):
   
7.         name = 'Dmoz'
   
8.         allowed_domains = ['dmoztools.net']
   
9.         start_urls = ['http://dmoztools.net/Society/Philosophy/Aesthetics/']
   
10. 
    
11.         def parse(self, response):
    
12.                 for sel in response.xpath('//*[@id="site-list-content"]/div[1]/div[3]'):
    
13.                         item = DmozItem()
    
14.                         item['title'] = sel.xpath('a/@href').extract()
    
15.                         item['link'] = sel.xpath('a/div/text()').extract()
    
16.                         item['comment'] = sel.xpath('div/text()').extract()
    
17.                         yield item

复制代码

我的工程和代码目录如下
dmoz/dmoz/items.py
dmoz/dmoz/spiders/dmoz.py

报错提示：

ImportError: No module named items
这个错误已经很明显了吧，另外这个items是你自己写的python吧，你搜索“python import 自己的模块”基本就能得到答案
