我已经安装了emmet-vim，并且一切正常。 当我在vimrc中添加此内容时：
let g:user_emmet_install_global = 0
autocmd FileType html,css EmmetInstall
出现下一个错误：
Error detected while processing FileType Auto commands for "html":
E492: Not an editor command: EmmetInstall
有我的vimrc：
" If using a dark background within the editing area and syntax highlighting
" turn on this option as well
"set background=dark
" Uncomment the following to have Vim jump to the last position when
" reopening a file
"if has("autocmd")
" au BufReadPost * if line("'\"") > 1 && line("'\"") <= line("$") | exe "normal! g'\"" | endif
"endif
" Uncomment the following to have Vim load indentation rules and plugins
" according to the detected filetype.
"if has("autocmd")
" filetype plugin indent on
"endif
" The following are commented out as they cause vim to behave a lot
" differently from regular Vi. They are highly recommended though.
"set showcmd " Show (partial) command in status line.
"set showmatch " Show matching brackets.
"set ignorecase " Do case insensitive matching
"set smartcase " Do smart case matching
"set incsearch " Incremental search
"set autowrite " Automatically save before commands like :next and :make
"set hidden " Hide buffers when they are abandoned
"set mouse=a " Enable mouse usage (all modes)
" Source a global configuration file if available
if filereadable("/etc/vim/vimrc.local")
source /etc/vim/vimrc.local
endif
