vim-isort not working with anaconda isort

[brityboy]

FIrst of all, very cool plugin, thank you for making this.

I followed the instructions and when I hit pip install isort, I was happy to see this response from my terminal

Requirement already satisfied: isort in /anaconda/lib/python2.7/site-packages

I selected the lines I wanted to sort, hit Ctrl-i and got this in response

No isort python module detected, you should install it. More info at https://github.com/fisadev/vim-isort

Confused, I tried setting my python version with this in my vimrc file

let g:vim_isort_python_version = 'anaconda/lib/python2.7/site-packages'

But got this as a response

Trying this let g:vim_isort_python_version = 'anaconda/lib/python2.7' returned the same result as above

Help please? Thanks for the awesome plugin!

I also hit
:py import isort and got this in response

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/anaconda/lib/python2.7/site-packages/isort/__init__.py", line 25, in <module>
    from . import settings
ImportError: cannot import name settings

When opening up python via terminal, the command import isort works

Thanks again!

I find the g:vim_isort_python_version option confusing. It looks like you might be able to specify a path to a python interpreter, but in reality it is only looking for a match on the string python3 or python2. Providing anything but those two strings results in the confusing error mentioned above:
