scrapy crawl cnblog时为什么总出现下面的这堆错误

zouxfbj 2017-08-02 08:52:46

[size=14px]今天开始学习scrapy框架，当执行爬虫敲入命令scrapy crawl cnblogs时，总是提示下面这一大堆，网上也搜不到相关的解释，忘论坛大家帮忙解答一下。

scrapy crawl cnblogs ，其中cnblogs是我的爬虫name

我的笔记本是64位，安装的是python2.7 ，安装目录在c:\python27

安装scrapy前，各依赖项都安装成功，在python命令行下
执行import lxml，没报错，
执行import twisted，没报错，
执行import OpenSSL，没报错，
执行import zope.interface，没报错，

然后安装的是Scrapy 0.14.4

在D盘创建目录cnblog，然后在此目录下执行scrapy startproject cnblogSpider
然后用pcCharm打开一个新项目，把目录设置成上述目录，然后随便写了一个爬虫模块的代码，保存在cnblogspider/spiders目录下
文件取名，cnblogs_spider.py, 文件里的代码就这几行

#coding:utf-8
import scrapy
class CnblogsSpider(scrapy.Spider):
name = "cnblogs"
allowd_domains = ["cnblogs.com"]
start_urls = ["http://www.cnblogs.com/qiyeboy/default.html?page=1"]
def parse(self,response):
pass

然后在D:\cnblogs\cnblogsSpider>目录下运行 scrapy crawl cnblogs，然后总是报这堆错误

D:\cnblogs\cnblogsSpider>scrapy crawl cnblogs
