How to get scrapy to use python 3 when both python versions are installed?

Question

Quick question regarding the version of python that's being used by scrapy. I installed scrapy from the AUR repository on archlinux and it defaults on using python 2.7. Scrapy has support forpython 3.3+. Does anyone know how to force it to use 3.3 without uninstalling 2.7, can't find anything on it on the internet.

Answer 1

Use virtualenv. You can install it with pip.

What I would normally do is go to the project folder, and create a virtual environment (envname) with the following command:

virtualenv -p python3 envname

Enable it source envname/bin/activate and install everything you want. Now you have a Python3 environment (I think you need to install Scrapy again for the current environment).
