Failed building wheel for cryptography. Could not build wheels for cryptography which use PEP 517 and cannot be installed directly
sudo apt-get install python3 python3-dev python3-pip libxml2-dev libxslt1-dev zlib1g-dev libffi-dev libssl-dev
I couldn't install Scrapy on my system after I upgraded pip to 20.0.2.
And what file do I have to install manually in order to make it work?
Please help me out.
