Error installing scrapy 0.22 (on Ubuntu 12.04): &#

Question

When trying to install Scrapy from the command line using pip
sudo pip install scrapy
I get the following error:
error: command 'gcc' failed with exit status 1

Looking a few lines up in the error output, I see that the error occurs while trying to install the 'cryptography' package which seems to be a dependency of pyOpenSSL

I tried installing pyOpenSSL on its own and it gives the same error. Reading through the error output, I find that the likely cause of this error is a missing file:

ffi.h: No such file or directory

How should I proceed from here?

Answer 1

Try with

sudo apt-get install libffi libffi-dev
