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

  1: /home/users/xxx/.vimrc
  2: /home/users/xxx/tools/share/vim/vim73/colors/darkblue.vim
  3: /home/users/xxx/tools/share/vim/vim73/syntax/syntax.vim
  4: /home/users/xxx/tools/share/vim/vim73/syntax/synload.vim
  5: /home/users/xxx/tools/share/vim/vim73/syntax/syncolor.vim
  6: /home/users/xxx/tools/share/vim/vim73/filetype.vim
  7: /home/users/xxx/tools/share/vim/vim73/plugin/getscriptPlugin.vim
  8: /home/users/xxx/tools/share/vim/vim73/plugin/gzip.vim
  9: /home/users/xxx/tools/share/vim/vim73/plugin/matchparen.vim
 10: /home/users/xxx/tools/share/vim/vim73/plugin/netrwPlugin.vim
 11: /home/users/xxx/tools/share/vim/vim73/plugin/rrhelper.vim
 12: /home/users/xxx/tools/share/vim/vim73/plugin/spellfile.vim
 13: /home/users/xxx/tools/share/vim/vim73/plugin/tarPlugin.vim
 14: /home/users/xxx/tools/share/vim/vim73/plugin/tohtml.vim
 15: /home/users/xxx/tools/share/vim/vim73/plugin/vimballPlugin.vim
 16: /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

  1 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.
  3 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
  8 syntax on
  9 if &term =~ "xterm"
 10   if has("terminfo")
 11     set t_Co=8
 12     set t_Sf=^[[3%p1%dm
 13     set t_Sb=^[[4%p1%dm
 14   else
 15     set t_Co=8
 16     set t_Sf=^[[3%dm
 17     set t_Sb=^[[4%dm
 18   endif
 19 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=8
     set t_Sf=^[[3%p1%dm
     set t_Sb=^[[4%p1%dm
   else
     set t_Co=8
     set t_Sf=^[[3%dm
     set t_Sb=^[[4%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
