Unable to import name when starting Scrapy project

My project name is NOTHS.

The following scripts are for spider.py

and items.py

that I have used.

spider.py

:

from scrapy.spider import BaseSpider
from scrapy.selector import HtmlXPathSelector
from NOTHS.items import NOTHS
class MySpider(BaseSpider):
    name = "main"
    allowed_domains = ["notonthehighstreet.com"]
    start_urls = ["http://www.notonthehighstreet.com"]
    def parse(self, response):
        hxs = HtmlXPathSelector(response)
        titles = hxs.select("//a[@class='title']")
        items = []
        for titles in titles:
            item = NOTHS()
            item ["title"] = titles.select("a/text()").extract()
            item ["link"] = titles.select("a/@href").extract()
            items.append(item)
        return items 

      

        
        
        
      

    

items.py

:

from scrapy.item import Item, Field
class CraigslistSampleItem(Item):
    title = Field()
    link = Field()

      

        
        
        
      

    

When I run this, the following error occurs:

C:\Users\ACER\Documents\works\source code\NOTHS>scrapy crawl main
:0: UserWarning: You do not have a working installation of the service_identity
module: 'No module named service_identity'.  Please install it from <https://pyp

What am I doing wrong?
