Powerline Installation Issues for Vim/Tmux on Mac OSX 10.10.5

If you don’t want to try ronkag’s suggestion of trying vim-airline, here’s some things to try to get Powerline working correctly on your setup:

1. You’re ~/.vimrc looks a little funny, like it might be missing some stuff. Here’s mine for reference:

set nocompatible              " be iMproved, required
filetype off                  " required                                        

" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
" alternatively, pass a path where Vundle should install plugins
"call vundle#begin('~/some/path/here')

" let Vundle manage Vundle, required
Plugin 'VundleVim/Vundle.vim'


" plugin on GitHub repo
Plugin 'tpope/vim-fugitive'

" Git plugin not hosted on GitHub
Plugin 'git://git.wincent.com/command-t.git'


" All of your Plugins must be added before the following line
call vundle#end()            " required
filetype plugin indent on    " required
" To ignore plugin indent changes, instead use:
"filetype plugin on
"
" Brief help
" :PluginList       - lists configured plugins
" :PluginInstall    - installs plugins; append `!` to update or just :PluginUpdate
" :PluginSearch foo - searches for foo; append `!` to refresh local cache
" :PluginClean      - confirms removal of unused plugins; append `!` to auto-approve removal
"
" see :h vundle for more details or wiki for FAQ
" Put your non-Plugin stuff after this line

set laststatus=2         

if has("gui_running")
       let s:uname = system("uname")
          if s:uname == "Darwinn"
                    set guifont=Inconsolata for Powerline:h15
                       endif
                   endif


set guifont=Inconsolata for Powerline:h15
let g:Powerline_symbols = 'fancy'
set encoding=utf-8
set t_Co=256

" enable syntax highlighting
syntax enable

" show line numbers
set number

" set tabs to have 4 spaces
set ts=4

" indent when moving to the next line while writing code
set autoindent

" expand tabs into spaces
set expandtab   

" when using the >> or << commands, shift lines by 4 spaces
set shiftwidth=4

" show a visual line under the cursor's current line 
set cursorline

" show the matching part of the pair for [] {} and ()
set showmatch

" enable all Python syntax highlighting features
let python_highlight_all = 1 

2. What you have in your ~/.tmux.conf file doesn’t look right either. You have to specify the actual file path of where the powerline.conf file is. For example, mine looks like this:

source /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/powerline/bindings/tmux/powerline.conf

3. Assuming you did correctly install all of the fonts from the fonts package (you should double check since you did it manually), and this may be an obvious one, but don’t forget to select a Powerline font in Terminal preferences! Any font that has “for powerline” in it should work.
