解决vim没有颜色的办法

首先打开vim，输入命令 scriptnames看看vim加载了哪些脚本。

:scriptnames

输出入下

  : /home/users/xxx/.vimrc
  : /home/users/xxx/tools/share/vim/vim73/colors/darkblue.vim
  : /home/users/xxx/tools/share/vim/vim73/syntax/syntax.vim
  : /home/users/xxx/tools/share/vim/vim73/syntax/synload.vim
  : /home/users/xxx/tools/share/vim/vim73/syntax/syncolor.vim
  : /home/users/xxx/tools/share/vim/vim73/filetype.vim
  : /home/users/xxx/tools/share/vim/vim73/plugin/getscriptPlugin.vim
  : /home/users/xxx/tools/share/vim/vim73/plugin/gzip.vim
  : /home/users/xxx/tools/share/vim/vim73/plugin/matchparen.vim
 : /home/users/xxx/tools/share/vim/vim73/plugin/netrwPlugin.vim
 : /home/users/xxx/tools/share/vim/vim73/plugin/rrhelper.vim
 : /home/users/xxx/tools/share/vim/vim73/plugin/spellfile.vim
 : /home/users/xxx/tools/share/vim/vim73/plugin/tarPlugin.vim
 : /home/users/xxx/tools/share/vim/vim73/plugin/tohtml.vim
 : /home/users/xxx/tools/share/vim/vim73/plugin/vimballPlugin.vim
 : /home/users/xxx/tools/share/vim/vim73/plugin/zipPlugin.vim

可见所有和语法及颜色相关的脚本都已经加载了，应该不是它们的问题。

在看.vimrc配置文件

   set nocompatible        " Vim settings, not Vi settings.  must be first
  2 set autoindent          " Auto align when insert new line, for instance, when using o or O to insert new line.
   set ruler               " Show ruler at the bottom-right of vim window
  4 set showcmd
  5 set backspace=indent,eol,start          " Enable delete for backspace under insert mode"
  6 colorscheme darkblue
  7 set number              " Show line number
   syntax on
   if &term =~ "xterm"
    if has("terminfo")
      set t_Co=
      set t_Sf=^[[%p1%dm
      set t_Sb=^[[%p1%dm
    else
      set t_Co=
      set t_Sf=^[[%dm
      set t_Sb=^[[%dm
    endif
  endif

从第9行开始，如果用的是xterm，那就就进行下面的颜色设置，那么如果系统用的不是xterm呢？于是赶紧查看，在shell终端输入如下命令

echo $TERM

结果如下

vt100+

果然不是xterm，怪不得没有颜色。

解决办法：打开shell配置文件，.bash_profile或.bashrc加入下面一行

TERM=xterm
export TERM

PS

  set nocompatible        " Vim settings, not Vi settings.  must be first
  set autoindent          " Auto align when insert new line, for instance, when using o or O to insert new line.
  set ruler               " Show ruler at the bottom-right of vim window
  set showcmd
  set backspace=indent,eol,start          " Enable delete for backspace under insert mode"
  colorscheme darkblue
  set number              " Show line number
  syntax on
  if &term =~ "xterm"
    if has("terminfo")
      set t_Co=
      set t_Sf=^[[%p1%dm
      set t_Sb=^[[%p1%dm
    else
      set t_Co=
      set t_Sf=^[[%dm
      set t_Sb=^[[%dm
    endif
  endif

.bashrc加入下面

TERM=xterm

export TERM

再运行下脚本source .bashrc或source .bash_profile

修改终端设置
