Neovim prompts that there is no matching automatic command

Question

After installing the vim airline plug-in, every time I open a file, I will be prompted that there is no matching automatic command.
Can you turn off this prompt?

The following is my init.vim configuration file:

call plug#begin('~/.config/nvim/plugged') " vim-plug 初始化

"""
" 插件列表
"""

Plug 'vim-airline/vim-airline'
Plug 'vim-airline/vim-airline-themes'

" 结束插件列表
call plug#end()

You can put :version的输出贴一下，如果insert_expand的前面是减号-, that is, your VIM installation does not support automatic completion, so an error will be reported every time. As shown in the picture below:
