How can I resolve these errors when I open a file with vim?

So when I open a file (i.e., vi examples.R) on my Ubuntu 20.04 laptop, I get the following string of errors:

Error detected while processing /home/mikel/.vimrc:
line    1:
E319: Sorry, the command is not available in this version: call plug#begin('~/.vim/plugged')
line    2:
E492: Not an editor command: Plug 'sheerun/vim-polyglot'
line    3:
E492: Not an editor command: Plug 'trevordmiller/nova-vim'
line    4:
E492: Not an editor command: Plug 'jalvesaq/Nvim-R'
line    6:
E319: Sorry, the command is not available in this version: call plug#end()
Press ENTER or type command to continue

My ~/.vimrc file is:

call plug#begin('~/.vim/plugged')
Plug 'sheerun/vim-polyglot'
Plug 'trevordmiller/nova-vim'
Plug 'jalvesaq/Nvim-R'

call plug#end()

I don’t even know where to begin when diagnosing this issue. Do any of you have any thoughts? Thank you!

Answer

It looks like you broke your .vimrc, and that your vi is just an alias to vim. Try either fixing up your configuration (it looks to me that Vundle got messed up somehow) or delete ~/.vimrc and start again.
