Question

我在Windows的cmd行中运行gulp。当我编辑SCSS文件时，除非激活cmd窗口，否则不会启动gulp watch。这是正常行为吗？

这是我的gulpfile：

    // grab our packages
var gulp   = require('gulp'),
    sass = require('gulp-ruby-sass')
    autoprefixer = require('gulp-autoprefixer'),
    minifycss = require('gulp-minify-css'),
    rename = require('gulp-rename');;

// define the default task and add the watch task to it
gulp.task('default', ['watch']);


gulp.task('build-css', function() {
    return sass('src/scss/**/*.scss', {
        style: 'expanded'
    })
        .pipe(gulp.dest('public/css/'))
        .pipe(rename({suffix: '.min'}))
        .pipe(minifycss())
        .pipe(gulp.dest('public/css'));
});

// configure which files to watch and what tasks to use on file changes
gulp.task('watch', function() {
    gulp.watch('src/scss/**/*.scss', ['build-css']);
});
