Why doesn't Vim recognize that I have Python installed?

Question

I'm on the latest version of Arch Linux. The version of Vim from the Arch repos doesn't have python support, so I downloaded the source code and built it from that. I have checked, and Python support is enabled. I have Python installed on my system. However, when I try to start vim with a plugin which requires Python, I get a warning before vim opens, and the plugin doesn't function properly: vim-llp: python required. Do I have to tell vim that Python exists during the installation process or something?

The :version output is the following:

Answer 1

This vim is compiled without python:

-python
-python3

You can also see has().

To fix this you’ll need to install a vim built with python support.
