jedi-vim failed to initialize Python: ":py/py3 import jedi" gives "ImportError: cannot import name 'settings'"

I get the following error every time I start VIM

Error: jedi-vim failed to initialize Python: jedi#setup_py_version: Vim(py3file):Traceback (most recent call last): (in function jedi#init_python[3]..<SNR>72_init_python[50]..jedi
#setup_py_version, line 18)

I am running on Mac OS X El Captain 10.11.2. Vim is version 7.4.1063, python is version 3.4.3. Jedi is 0.9.0. Both python and vim are installed using brew, vim is installed using --with-python3 flag. :py3 command works, but trying to do :py3 import jedi results in the following

Traceback (most recent call last):

    from jedi import settings
ImportError: cannot import name 'settings'

I tried reinstalling everything and re-installing vim with env vi_cv_path_python=/usr/local/bin/python3 brew install --force vim --with-python3 command as was suggested in a similar issue.

Here is :version output for more info.

Weird it happened to me today, my Python is 3.7

Please refer to this comment https://github.com/davidhalter/jedi-vim/issues/841#issuecomment-402297069

I’m pretty sure it’s an issue on brew with 3.7.
