Python 2.7.10 and scrapy Installation on CentOS 6.7 AWS

I know there are similar posts, but I've followed many instructions on installing python. (I'm no linux expert)

But I've constantly hit different problems...

The latest problem was this error:

Could not find a version that satisfies the requirement Twisted>=10.0.0 (from scrapy) (from versions: )

Some externally hosted files were ignored as access to them may be unreliable (use --allow-external Twisted to allow). No matching distribution found for Twisted>=10.0.0 (from scrapy)

This is my third try after wiping the server clean and starting from scratch.

Can someone help me with setting up python 2.7.10 and scrapy in a CentOS 6.7 AWS server? What do other dev tools do I need to install beforehand?
