Error detected while processing vimrc: - how to take pugins in vim

Question

Today I was making my custom vimrc, but it gives me this error. It is not allowing me to use any plugins. Can somebody help by telling what I am doing wrong? These lines are the error that it is showing:

You need to install vim-plug, you can find instructions on how to do that here: https://github.com/junegunn/vim-plug#installation
