I used to install scrapy before, never had issues, what's wrong?

@hbdgaf did that, and fixed it, it's just that you said Separate question then. Or you could try chat. so I thought I should show the error, you know what, nevermind — Lynob, Jul 19, 2014 at 9:44
@hbdgaf ok next time, I will ask such questions there if I have to, thanks, not really used for chat rooms that's why i often post here — Lynob, Jul 19, 2014 at 10:21
@hbdgaf lets burn them, i wanted to delete the question but I don't want for the user who answered it to lose rep — Lynob, Jul 19, 2014 at 13:54

I got this error, too. The problem is

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

You should do this:

sudo apt-get install libffi-dev

From a fresh installation of 14.04, I had to install python-dev, libffi-dev, libssl-dev, libxml2-dev, and libxslt1-dev packages. Once those were installed, pip install scrapy worked fine.

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

I have installed scrapy by using following two commands:

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

sudo apt-get install python-scrapy

check the version of scrapy by,

scrapy -V
