=======================Windows解决办法如下=======================

在$home/.vimrc(_vimrc)或在vim安装目录的_vimrc(.vimrc)文件中加入以下内容

set smarttab " 根据文件中其他地方的缩进空格个数来确定一个tab是多少个空格

set tabstop=4 " 表示一个table显示出来多少个空格

set shiftwidth=4 " 每一级缩进是多少个空格

set expandtab " 将tab扩展成空格

set autoindent " 继承前一行的缩进方式，特别适用于多行注释

set number " 显示行号

set ruler " 打开状态栏标尺

set iskeyword+=_,$,@,%,#,- " 带有如下符号的单词不要被换行分割

" 自选文件编码格式

" Multi-encoding setting, MUST BE IN THE BEGINNING OF .vimrc!
"
if has("multi_byte")
   " When 'fileencodings' starts with 'ucs-bom', don't do this manually
   "set bomb
set fileencodings=ucs-bom,chinese,taiwan,japan,korea,utf-8,latin1
   " CJK environment detection and corresponding setting
if v:lang =~ "^zh_CN"
     " Simplified Chinese, on Unix euc-cn, on MS-Windows cp936
    set encoding=chinese
    set termencoding=chinese
    if &fileencoding == ''
      set fileencoding=chinese
    endif
elseif v:lang =~ "^zh_TW"
     " Traditional Chinese, on Unix euc-tw, on MS-Windows cp950
    set encoding=taiwan
    set termencoding=taiwan
    if &fileencoding == ''
      set fileencoding=taiwan
    endif
elseif v:lang =~ "^ja_JP"
     " Japanese, on Unix euc-jp, on MS-Windows cp932
    set encoding=japan
    set termencoding=japan
    if &fileencoding == ''
      set fileencoding=japan
    endif
elseif v:lang =~ "^ko"
     " Korean on Unix euc-kr, on MS-Windows cp949
    set encoding=korea
    set termencoding=korea
    if &fileencoding == ''
      set fileencoding=korea
    endif
endif
    " Detect UTF-8 locale, and override CJK setting if needed
if v:lang =~ "utf8$" || v:lang =~ "UTF-8$"
    set encoding=utf-8
