Press ENTER or type command to continue

What's my problem?

    you apparently use Vundle, Neobundle and pathogen and perhaps even vim-plug to load plugins. You should clean this up and decide one one single plugin manager to use. Or use the native package feature that comes with Vim 8 – Christian Brabandt Sep 24 '18 at 14:51

    Christian is right, you should have a look at this and this – statox Sep 24 '18 at 14:56
  • Is it problem if I use 2 or higher plugin manager? – PersianGulf Sep 24 '18 at 15:43

    You have just discovered it is @PersianGulf :-) You could make it work with some effort perhaps, but I wouldn't recommend it. – Martin Tournoij Sep 24 '18 at 15:47

    @PersianGulf Strictly speaking, no. But practically, yes, because you're unnecessarily overcomplicating things, which is the root of your issue in this question. You wouldn't use pacman, yum and apt to manage packages on your Linux install, right? :) Same thing here. Each plugin manager works toward the same goal, but does so in its own way. Having all 3 intermix simultaneously is begging for problems. – ZeroKnight Sep 24 '18 at 18:11

The error message comes from the last line of your vimrc:

Plug 'rdnetto/YCM-Generator' , { 'branch': 'stable'}

This is a call to the Plug command of the Vim-plug plugin manager. To work, this line should be surrounded by the following lines as it's stated in the readme:

call plug#begin('~/.vim/plugged')
Plug 'rdnetto/YCM-Generator' , { 'branch': 'stable'}
call plug#end()

Now your real problem is that you try to use three or four different plugins managers: that is totally unnecessary. Instead you should have a read at our question What is the difference between the vim plugin managers?, decide which plugin manager you want to use and use only this one for all of your plugins.

At a second reading of your vimrc: you have plugins that you're trying to install several time (i.e. vim-fugitive) I guess it means that you blindly copied the vimrc of other people and mixed them together without understanding every line. That is not a good idea (your question is the proof of what I'm saying). You would probably loose less time crafting your own vimrc to fit your own needs than debugging someone else's config.
