Lint only works when saving files (using jedi)

[qifei9]

Problem:

the lint info never change when I type, it only updates when every time I save the file with :w. Both pylint and flake8 were tested, and even when I use a minimal init.vim and coc-settings.json and uninstall all the other plugins, the problem always remains.

Update:

It seems coc-json works fine for json files. Lint updates without saving file.

init.vim:

call plug#begin('~/.local/share/nvim/plugged')

Plug 'neoclide/coc.nvim', {'branch': 'release'}

call plug#end()


let g:coc_global_extensions = ['coc-python']

CocConfig:

{
    "python.jediEnabled": true
}

neovim v0.4.2
python 3.7.4

It can't work with unsaved buffer.

Q: MPLS doesn't work with unsaved buffer.

A: Yes, it's not. You have to save your buffer to make it work.

The FAQ only says about MPLS while I used jedi. Does it actually mean that both of MPLS and jedi do not work with unsaved buffer?

Should be both.
