My recommendation

In my Vim The front of the configuration file , There's a piece of code ：

if empty(glob('~/.vim/autoload/plug.vim'))

silent !curl -fLo ~/.config/nvim/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

autocmd VimEnter * PlugInstall --sync | source $MYVIMRC

endif

It will make vim Check every time you start vim-plug Has it been installed . If not ,vim Will try to install vim-plug, And it runs automatically :PlugInstall . If you're using a Neovim, Please put ~/.vim/autoload/plug.vim Switch to ~/.config/nvim/autoload/plug.vim
