Python Scrapy:导入错误：无法导入名称设置

我在尝试使用scrapy.conf.settings中的CrawlerProcess（settings）时出错，看起来scrapy文档中的内容不一致

我正在遵循一个旧的scrapy版本，我正在尝试使它与0.16的scrapy一起工作

这是我运行python脚本时出现的错误

from scrapy import project, signals
from scrapy.crawler import Settings
from scrapy.crawler import CrawlerProcess
from scrapy.xlib.pydispatch import dispatcher
from multiprocessing.queues import Queue
import multiprocessing

class CrawlerWorker(multiprocessing.Process):

    def __init__(self, spider, result_queue):
        multiprocessing.Process.__init__(self)
        self.result_queue = result_queue

        self.crawler = Crawler(Settings())
        if not hasattr(project, 'crawler'):
            self.crawler.install()
        self.crawler.configure()

        self.items = []
        self.spider = spider
        dispatcher.connect(self._item_passed, signals.item_passed)

    def _item_passed(self, item):
        self.items.append(item)

    def run(self):
        self.crawler.crawl(self.spider)
        self.crawler.start()
        self.crawler.stop()
        self.result_queue.put(self.items)

回溯（最近一次呼叫最后一次）：
文件“server.py”，第5行，在
从刮板进口刮板
文件“/home/me/spider/spider/scraper.py”，第6行，在
从crawlerworker导入crawlerworker
文件“/home/me/spider/spider/crawlerworker.py”，第2行，在
从scrapy.crawler导入设置
导入错误：无法导入名称设置

试试：

Traceback (most recent call last):
  File "server.py", line 5, in <module>
    from scraper import Scraper
  File "/home/me/spider/spider/scraper.py", line 6, in <module>
    from crawlerworker import CrawlerWorker
  File "/home/me/spider/spider/crawlerworker.py", line 2, in <module>
    from scrapy.crawler import Settings
ImportError: cannot import name Settings

尝试：
