If Vim's Python interface path settings aren't working properly, completion won't work with Python-based plugins, such as jedi-vim. Or when using vim-geeknote
function Vim_An error was detected while processing GeeknoteToggle:

I get the error.
This happens because the Python referenced by Vim's Python interface is different from the Python you intended.
On a Mac, this happens when you install Python with Homebrew and use MacVim-KaoriYa.
Check version and sys.path on the command line
~$ python -c 'import sys; print(sys.version); print(sys.path);'

It turns out that version and sys.path are different. If you try using standard Python for Mac
~$ /usr/bin/python -c 'import sys; print(sys.version); print(sys.path);'

The sys.path is slightly different, but the version is the same, and you can see that Vim uses this Python.

let $PYTHON_DLL = "/usr/local/Cellar/python/2.7.9/Frameworks/Python.framework/Versions/2.7/Python"
And check version and sys.path again

The version has changed, but sys.path hasn't changed. So I decided to call Python from vim using the system function and add it to sys.path.
:!which python
Try it, make sure you have a Python PATH, and put it in vimrc
let s:python_path = system('python -', 'import sys;sys.stdout.write(",".join(sys.path))')
python <<EOM
import sys
import vim
python_paths = vim.eval('s:python_path').split(',')
for path in python_paths:
if not path in sys.path:
sys.path.insert(0, path)
EOM
If you write, you can see that sys.path has been added.
However, with this, even if you do not need the Python interface, system will be called every time you start Vim, so set it only when using a plugin that requires a Python interface using NeoBundleLazy etc.
Finally set it like this.
NeoBundleLazy 'davidhalter/jedi-vim', {
\ 'autoload': {'filetypes': ['python']}
\}
:
"python sys.path setting" {{{
if filereadable('/usr/local/Cellar/python/2.7.9/Frameworks/Python.framework/Versions/2.7/Python')
let $PYTHON_DLL = "/usr/local/Cellar/python/2.7.9/Frameworks/Python.framework/Versions/2.7/Python"
endif
function! s:set_python_path()
let s:python_path = system('python -', 'import sys;sys.stdout.write(",".join(sys.path))')
python <<EOT
import sys
import vim
python_paths = vim.eval('s:python_path').split(',')
for path in python_paths:
if not path in sys.path:
sys.path.insert(0, path)
EOT
endfunction
" }}}
let s:hooks = neobundle#get_hooks("jedi-vim")
function! s:hooks.on_source(bundle)
call s:set_python_path()
:
endfunction
"setting the path option
autocmd MyVimrc FileType python
\ let &l:path = system('python -', 'import sys;sys.stdout.write(",".join(sys.path))')
Finally, I added the setting of Vim's path option. This is used for include completion of neocomplete & neocomplcache and for directories that are searched when using gf.
How to fetch Python sys.path is described in How to use include completion of neocomplcache.vim-forever incomplete I referred to.
