Daha önce scrapy yaptırdım, hiç sorun yaşamadım, sorun ne?

14.04  python  python-2.7  virtualenv  pip

@hbdgaf Ben şimdi kurdum ve başka bir sorun var demek istedim
— Lynob
@hbdgaf burada yeni hata pastebin.com/cpCRDVxH
— Lynob
@hbdgaf bunu yaptı ve düzeltti, sadece dedin ki Separate question then. Or you could try chat.ben de hatayı göstereyim demiştim, ne biliyorsun, boşver
— Lynob
@hbdgaf, bir dahaki sefere, eğer o zaman bu tür soruları soracağım, gerekirse, sohbet salonları için gerçekten kullanılmaz, bu yüzden sık sık burada
— Lynob
@hbdgaf onları yakmayı sağlar, soruyu silmek istedim ancak cevabı kaybeden kullanıcının cevap vermesini istemiyorum

Ben de bu hatayı aldım. Problem şu

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

Bunu yapmalısın:

sudo apt-get install libffi-dev
— görünüyor

Bunu denedim ve ben de libssl-dev'i kurmak zorunda kaldım
— Lynob
Ben çalışırken bu sorunu yaşıyorum pip3 install cairocffi. Bunu çözdü. Teşekkür ederim!

Amazon Linux:sudo yum install libffi-devel

Yeni bir 14.04 kurulumundan sonra, python-dev, libffi-dev, libssl-dev, libxml2-dev ve libxslt1-dev paketlerini kurmak zorunda kaldım. Bunlar kurulduktan sonra pip install scrapyiyi çalıştı.

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

Ben bu hatayla yüzleşiyorum: `------------------------------------------ / bin / python -u -c "setuptools alma, tokenize; __ file __ = '/ tmp / pip-build-0R1XKL / lxml / setup.py'; exec (derleme (getattr (tokenize, 'open', open) ( dosya )) .read (). change ('\ r \ n', '\ n'), dosya , 'exec')) "install --record /tmp/pip-T9Uhnd-record/install-record.txt --single- sürüm-harici olarak yönetilen - derleme "hata kodu 1 / tmp / pip-build-0R1XKL / lxml /` ile başarısız oldu

Aşağıdaki iki komutu kullanarak scrapy kurdum:

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

sudo apt-get install python-scrapy

Scrapy versiyonunu kontrol ederek,

scrapy -V
