Tôi đã từng cài đặt phế liệu trước đây, không bao giờ có vấn đề, có gì sai?

14.04  python  python-2.7  virtualenv  pip

@hbdgaf Ý tôi là tôi đã cài đặt nó ngay bây giờ và tôi gặp một vấn đề khác
— Lynob
@hbdgaf đây là lỗi mới pastebin.com/cpCRDVxH
— Lynob
@hbdgaf đã làm điều đó và đã sửa nó, chỉ là bạn đã nói Separate question then. Or you could try chat.nên tôi nghĩ tôi nên hiển thị lỗi, bạn biết không,
— đừng bận tâm
@hbdgaf ok lần sau, tôi sẽ hỏi những câu hỏi như vậy nếu tôi phải, cảm ơn, không thực sự được sử dụng cho các phòng chat đó là lý do tại sao tôi thường đăng bài ở đây
— Lynob
@hbdgaf cho phép ghi chúng, tôi muốn xóa câu hỏi nhưng tôi không muốn người dùng trả lời bị mất
— Lynob

Câu trả lời:

Tôi cũng nhận được lỗi này. Vấn đề là

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

Bạn nên làm điều này:

sudo apt-get install libffi-dev
— dường như

đã thử điều đó và tôi cũng phải cài đặt libssl-dev
— Lynob
Tôi đã gặp vấn đề đó trong khi cố gắng pip3 install cairocffi. Nó đã giải quyết nó. Cảm ơn bạn!

Từ bản cài đặt mới 14.04, tôi đã phải cài đặt các gói python-dev, libffi-dev, libssl-dev, libxml2-dev và libxslt1-dev. Một khi chúng đã được cài đặt, pip install scrapyhoạt động tốt.

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

Đây là nhật ký đầy đủ của tôi: gist.github.com/donhuvy/1cc55b4ed6a5c8a6e458fce62c51e337 Tôi cố gắng cài đặt phế liệu trên CentOS 7 - x64

Tôi đã cài đặt phế liệu bằng cách sử dụng hai lệnh sau:

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

sudo apt-get install python-scrapy

kiểm tra phiên bản của phế liệu bằng cách,

scrapy -V
