Powerline in vim errors setting up

Question

I installed powerline using pip install as per their installation recommendations. I have it working fine in both zsh as a prompt and tmux as a statusline yet I can't get it to work in vim.

When I add the following to my vimrc:

python from powerline.vim import setup as powerline_setup
python powerline_setup()
python del powerline_setup

I get the following errors

Error detected while processing /home/jordan/.vimrc:
line    1:
E319: Sorry, the command is not available in this version: python from powerline.vim import setup as powerline_setup
line    2:
E319: Sorry, the command is not available in this version: python powerline_setup()
line    3:
E319: Sorry, the command is not available in this version: python del powerline_setup

EDIT: After checking that my version of vim (vim.gnome) is compiled with python support I noticed it is (python3). So I changed the vimrc to use python3 as per the installation instructions and get the following:

Error detected while processing /home/jordan/.vimrc:
line    1:
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named 'powerline'
line    2:
Traceback (most recent call last):
  File "<string>", line 1, in <module>
NameError: name 'powerline_setup' is not defined
line    3:
Traceback (most recent call last):
  File "<string>", line 1, in <module>
NameError: name 'powerline_setup' is not defined

Any ideas, im at my wits end with this!

SOLVED EDIT: I was unable to get it to work with python3 but it seems that is the only version of python supported in vim.gnome and vim.basic.

I installed vim.nox apt install vim-nox-py2 with python 2 support and it all works. Hopefully this solves somebody else a headache.

Solution

I fixed it as follows:

1. edit ~/.vimrc and changepython to python3 in each of the 3 lines in the original question above
2. sudo apt-get install python3-pip
3. pip3 install --user powerline-status
