scrapy 홈 페이지 에 따라(https://doc.scrapy.org/en/latest/intro/install.html#things-tat-are-good-to-know)의 요구.다음 과 같은 요 구 를 만족 시 켜 야 합 니 다. 

The minimal versions which Scrapy is tested against are:

Twisted 14.0
lxml 3.4
pyOpenSSL 0.14

현재 기계 에 설 치 된 module 버 전 을 확인 하 십시오.다음 과 같 습 니 다.

 pip list | egrep 'Twisted|lxml|pyOpenSSL'
lxml (3.3.3)
pyOpenSSL (0.13)
Twisted (18.9.0)
Twisted-Core (13.2.0)
Twisted-Web (13.2.0)
