@hdgaf ने ऐसा किया, और इसे ठीक कर दिया, यह सिर्फ इतना है कि आपने कहा Separate question then. Or you could try chat.इसलिए मैंने सोचा कि मुझे त्रुटि दिखानी चाहिए, आप जानते हैं कि क्या, कभी नहीं

@hbdgaf ठीक है अगली बार, मैं वहां ऐसे प्रश्न पूछूंगा अगर मुझे धन्यवाद देना है, तो वास्तव में चैट रूम के लिए उपयोग नहीं किया जाता है, इसलिए मैं अक्सर यहां पोस्ट करता

मुझे भी यह त्रुटि मिली। यह समस्या है

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

तुम्हें यह करना चाहिए:

sudo apt-get install libffi-dev

कोशिश की कि और मुझे libssl-dev को भी स्थापित करना था
— लिनोब जूल
कोशिश करते समय मुझे वह समस्या हो गई है pip3 install cairocffi। इसका हल निकाला। धन्यवाद!

14.04 की एक ताज़ा स्थापना से, मुझे अजगर-देव, लिबफी-देव, लिबासल-देव, लिबक्सएमएल 2-देव, और लिबक्सस्लेट 1-देव संकुल स्थापित करना पड़ा। एक बार स्थापित होने के बाद, pip install scrapyठीक काम किया।

मैंने निम्नलिखित दो आदेशों का उपयोग करके स्क्रैपी स्थापित किया है:

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

sudo apt-get install python-scrapy

द्वारा स्क्रैपी के संस्करण की जाँच करें,
