이 오류도 발생했습니다. 문제는

 No package 'libffi' found
 c/_cffi_backend.c:13:17: fatal error: ffi.h: No such file or directory
 #include <ffi.h>

이 작업을 수행해야합니다.

sudo apt-get install libffi-dev

14.04를 새로 설치 한 후에는 python-dev, libffi-dev, libssl-dev, libxml2-dev 및 libxslt1-dev 패키지를 설치해야했습니다. 일단 설치되면 pip install scrapy정상적으로 작동했습니다.

sudo apt-get install python-dev libffi-dev libssl-dev libxml2-dev libxslt1-dev
pip install scrapy

다음 두 명령을 사용하여 scrapy를 설치했습니다.

sudo apt-get install python-dev libffi-dev libssl-dev libxml2-dev libxslt1-dev

sudo apt-get install python-scrapy

스크랩의 버전을 확인하여
