ubuntu14.04 - vim配置疑问

问题描述

问 题

在ubuntu14.04下，用的root用户操作，在家目录下没有 ~/.vimrc文件，因此修改/etc/vim/vimrc文件。
没修改之前 source vimrc即出现错误。

请问这是什么问题。
$ cat vimrc

" All system-wide defaults are set in $VIMRUNTIME/debian.vim and sourced by
" the call to :runtime you can find below. If you wish to change any of those
" settings, you should do it in this file (/etc/vim/vimrc), since debian.vim
" will be overwritten everytime an upgrade of the vim packages is performed.
" It is recommended to make changes after sourcing debian.vim since it alters
" the value of the 'compatible' option.

" This line should not be removed as it ensures that various options are
" properly set to work with the Vim-related packages available in Debian.
runtime! debian.vim

" Uncomment the next line to make Vim more Vi-compatible
" NOTE: debian.vim sets 'nocompatible'. Setting 'compatible' changes numerous
" options, so any other options should be set AFTER setting 'compatible'.
"set compatible

" Vim5 and later versions support syntax highlighting. Uncommenting the next
" line enables syntax highlighting by default.
if has("syntax")
syntax on
endif

" 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

请问这里面有什么问题吗？

我现在需要加一个PHP不全的功能。
echo autocmd FileType php set omnifunc=phpcomplete#CompletePHP>>vimrc
source vimrc
现在出现了这个错误，是什么问题呢。

解决方案

source是用于配置当前shell环境的，vim不能用source命令。vim在下次启动后会自动读取vimrc，并不需要source。

~/.vimrc不存在可以用touch ~/.vimrc来创建，vim启动的时候会自动去读取它。
