Downloading and processing files and images . scrapy provides reusable item pipelines for downloading files attached to a particular item (for example, when you scrape products and also want to download their images locally). these pipelines share a bit of functionality and structure (we refer to them as media pipelines), but typically you’ll either use the files pipeline or the images pipeline. Once you have created a virtualenv, you can install scrapy inside it with pip, just like any other python package.(see platform specific guides below for non python dependencies that you may need to install beforehand) python virtualenvs can be created to use python 2 by default, or python 3 by default.
