I'm new to installing packages in unix and python. I'm working on Bash on Ubuntu on Windows. I wanted to start learning Scrapy, which I installed using:

apt-get install scrapy

When I'm trying to create a project, I'm getting the following error:

root > scrapy startproject tutorial
Traceback (most recent call last):

I verified that the above file is available. I'm trying to understand if there is any prerequisite(s) I missed to install (which I doubt, as I understand that they are handled during installation - please correct me if I'm wrong), or is there anything I need to enable.

Thanks, Sasi

• What's wrong / what should be happening instead:
  I'm supposed to be able to start with scrapy, which I'm unable to.

• Strace of the failing command, if applicable: (If <cmd> is failing, then run strace -o strace.txt -ff <cmd>, and post the strace.txt output here)

root > strace -o strace.txt -ff scrapy startproject tutorial

ImportError: /usr/local/lib/python2.7/dist-packages/cryptography/hazmat/bindings/_openssl.so: cannot enable executable stack as shared object requires: Invalid argument

I'm guessing everyone's crypto libraries must have levelled recently (for some value of recent). #2562, #2553, #916, #442, #286 et al.
