并找到很长的加载 sass.vim
它来源：
if exists("loaded_sass_syntax_checker")
finish
endif
let loaded_sass_syntax_checker = 1
"bail if the user doesnt have the sass binary installed
if !executable("sass")
finish
endif
"use compass imports if available
let g:syntastic_sass_imports = ""
if executable("compass")
let g:syntastic_sass_imports = system("compass imports")
endif
function! SyntaxCheckers_sass_GetLocList()
let makeprg='sass '.g:syntastic_sass_imports.' --check '.shellescape(expand('%'))
let errorformat = '%ESyntax %trror:%m,%C on line %l of %f,%Z%m'
let errorformat .= ',%Wwarning on line %l:,%Z%m,Syntax %trror on line %l: %m'
let loclist = SyntasticMake({ 'makeprg': makeprg, 'errorformat': errorformat })
let bn = bufnr("")
for i in loclist
let i['bufnr'] = bn
endfor
return loclist
endfunction
这个文件有什么问题？
