Issue Details

I'm heavily rely on anaconda to code python in v3.6, and I installed python and a batch of packages via miniconda. I want to get autocompletions for packages installed by miniconda, so I tried following workarounds.

1. configure g:ycm_python_sys_path and g:ycm_python_interpreter_path in .vimrc

NOT work

let g:ycm_python_interpreter_path = '/usr/local/miniconda3/bin/python'
let g:ycm_python_sys_path = ['/usr/local/miniconda3/lib/python3.6']

2. configure sys_path and interpreter_path in .ycm_extra_conf.py and load

work But this is not a solution for global environment.

def Settings( **kwargs ):
  return {
    'interpreter_path': '/usr/local/miniconda3/bin/python'
    'sys_path': [
      '/usr/local/miniconda3/lib/python3.6',
    ]
  }

3. configure g:ycm_python_sys_path, g:ycm_python_interpreter_path, g:ycm_extra_conf_vim_data and g:ycm_global_ycm_extra_conf in .vimrc and link to ~/.ycm_global_extra_conf.py

work .vimrc

let g:ycm_python_interpreter_path = '/usr/local/miniconda3/bin/python'
let g:ycm_python_sys_path = ['/usr/local/miniconda3/lib/python3.6']
let g:ycm_extra_conf_vim_data = [
 \'g:ycm_python_interpreter_path',
 \'g:ycm_python_sys_path']
let g:ycm_global_ycm_extra_conf = '~/.ycm_global_extra_conf.py'

~/.ycm_global_extra_conf.py

def Settings(**kwargs):
    client_data = kwargs['client_data']
    return {
        'interpreter_path': client_data['g:ycm_python_interpreter_path'],
        'sys_path': client_data['g:ycm_python_sys_path']
    }

Trial an error turned out to these results although I did not quite understand the differences.

configure g:ycm_python_sys_path and g:ycm_python_interpreter_path in .vimrc NOT work

It doesn't work because these options are not defined by YCM. They are just an example of how you can set sys.path and the Python interpreter path through Vim options with a global extra conf. You could name them to something completely different like g:my_sys_path and g:my_interpreter_path.

work But this is not a solution for global environment.

It is. You just need to use a global extra conf. See the g:ycm_global_ycm_extra_conf option.

If you have more questions, please ask them on the Gitter room or the ycm-users Google group.
