Jedi-vim yield the error on startup: ImportError: bad magic number in 'jedi.common': b'\x03\xf3\r\n'

[petRUShka]

Issue

After update to commit https://github.com/davidhalter/jedi-vim/commit/a17b0333031bd3652ad4c6169caaed05ffb7c49d (Update Jedi to v0.17.2) Jedi won't start on python files with an error:

ERROR: could not import the "jedi" Python module: ImportError: bad magic number in 'jedi.common': b'\x03\xf3\r\n'

If I come back to https://github.com/davidhalter/jedi-vim/commit/a0207fadf9f165adac61f01abc07db0ae898cbe6 everything is working as usual.

Steps to reproduce

1. Setup vimrc_minimal_jedi:

set nocompatible

let script_dir = fnamemodify(expand('<sfile>'), ':h')
let &runtimepath .= ','.script_dir.','.script_dir.'/after'

" Put your config changes here.
" let g:jedi#show_call_signatures=1
let g:jedi#completions_enabled = 0

syntax on
filetype plugin indent on

2. cd ~/vim/plugged/jedi-vim and execute vim test.py -u vimrc_minimal_jedi.
3. Get the error.

This means that your Jedi installation is broken. Remove the folder and reinstall it.

(You can also just clear all pyc files in the Jedi folder)
