Error on Plug command in Vim

[JustinY97]

Explain the problem here ... I am getting an error when I run the :source ~/.vimrc telling me that Plug is not a recognized command. I have added the plug.vim in my .vim/autoload folder. but nothing works.

call plug#begin()

    Plug 'preservim/nerdtree'

call plug#end()

:version gives
