Question

Я учусь Scrapy, из документации Scrapy в http://doc.scrapy.org/en/1.0/intro/overview.html входе I

scrapy runspider stackoverflow_spider.py -o top-stackoverflow-questions.json

и CMD подскажет

ImportError: DLL load failed: %1 is not a valid Win32 application.

Деталь:

Answer 1

Я имел та же проблема. Я загружаю и устанавливаю Win64OpenSSL_Light-1_0_2h, и это сработало.

pip install -I cryptography
