Prepare your vim environment to work with clang-format

Question

Problem

E319: Sorry, this command is not available in this version.

Problem
When I start the vim environment and try to reformat the code (CTRL + K), I get this warning on the screen

Environment:
System: Mac OS X

Settings:
Vim:

VIM - Vi IMproved 8.0 (2016 Sep 12, compiled Nov 17 2016 20:17:27)
MacOS X (unix) version
Included patches: 1-91

python:

python --version: Python 3.5.2

What am I doing

• Vim update: 7.3 → 8.0
  
• Python update: ~ 2.7 → ~ 3.5
  

• I updated the .vimrc file
  from
  map <C-K> :pyf .../clang-format.py<cr> imap <C-K> <c-o>:pyf .../clang-format.py<cr>
  on
  map <C-K> ggVG :py3f .../clang-format.py<cr> imap <C-K> <c-o>:py3f .../clang-format.py<cr>

• I am also updating the clang format file
