[Chris Dukes]

Package: python-scrapy
Version: 1.0.0-1
Severity: important

Dear Maintainer,

* What led up to the situation?
Attempted to follow scrapy tutorial at http://doc.scrapy.org/en/latest/intro/tutorial.html
aptitude install scrapy
scrapy startproject tutorial
Failed with
Traceback (most recent call last):
  File "/usr/bin/scrapy", line 5, in <module>
    from pkg_resources import load_entry_point

pkg_resources.DistributionNotFound: The 'Scrapy==1.0.0' distribution was not found and is required by the application


* What exactly did you do (or not do) that was effective (or ineffective)?
Attempted installing pip prior to package.  Failed the same way.
Attempted clean install in docker container.  Failed the same way.
Completely reproducable with the following docker file
FROM debian:sid

RUN export DEBIAN_FRONTEND=noninteractive ;\
	apt-get update &&\
	apt-get -y dist-upgrade &&\
	apt-get -y install python-scrapy

RUN scrapy startproject tutorial

Currently attempting approach of creating docker container with python-pip to build scrapy from source.


* What outcome did you expect instead?
Expected a tutorial directory with skeleton scrapy project be created.
