我尝试用一​​个gulp编译我的sass然后autoprefixit gulp-autoprefixer但我得到一个错误.

var gulp = require('gulp'),
    sass = require('gulp-sass'),
    autoprefixer = require('gulp-autoprefixer');

gulp.task('test', function(){
    gulp.src('_sass/main.sass')
        .pipe(sass())
        .pipe(autoprefixer()) 
        .pipe(gulp.dest('./assets/css')); 
});

我正在尝试运行这个Gulpfile.js,我正在使用:

"gulp": "~3.9.0",
"gulp-sass": "~2.0.4",
"gulp-autoprefixer": "~3.0.1",

和NPM版本 1.3.10

当我跑gulp test我得到这个:
