私の vimrc は /usr/share/vim/vimrc にあり、使用したいテーマの .vim ファイルがあります。.vim テーマ ファイルを配置したディレクトリと、vimrc ファイルで変更した内容は? これが私のvimrcファイルです：
" All system-wide defaults are set in $VIMRUNTIME/debian.vim (usually just
" /usr/share/vim/vimcurrent/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

" 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 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)
