编译相应的gulp文件

Question

使用gulp &使用'gulp.watch'的Gulp-sass，如何返回监视列表中已更改项目的目录名称，以便我可以将sass编译为css？

这就是我目前所拥有的;正如你所看到的，只有一个目录被编译为主题1.如果主题2或3在SASS中发生变化，主题1 css将被更新。我希望它是有条件的，以便任何一个根据不同的变化而变化。

'use strict'; 

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

gulp.task('sass', function() { 
    return gulp.src('./wp-content/themes/1/assets/sass/**/*.scss') 
     .pipe(sass.sync().on('error', sass.logError)) 
     .pipe(gulp.dest('./wp-content/themes/1/')); 
}); 

gulp.task('sass:watch', function() { 
    gulp.watch('./wp-content/themes/1/assets/sass/**/*.scss', ['sass']); 
    gulp.watch('./wp-content/themes/2/assets/sass/**/*.scss', ['sass']); 
    gulp.watch('./wp-content/themes/3/assets/sass/**/*.scss', ['sass']); 
});

虽然这是非常硬编码，这是我刚刚找到的解决方案。

'use strict'; 

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

gulp.task('sass', function() { 
    // return gulp.src('./wp-content/themes/giggleselc/assets/sass/**/*.scss') 
    //  .pipe(sass.sync().on('error', sass.logError)) 
    //  .pipe(gulp.dest('./wp-content/themes/giggleselc/')); 
}); 

gulp.task('sass:watch', function() { 
    var n1 = gulp.watch('./wp-content/themes/1/assets/sass/**/*.scss', ['sass']); 
    var n2 = gulp.watch('./wp-content/themes/2/assets/sass/**/*.scss', ['sass']); 
    var n3 = gulp.watch('./wp-content/themes/3/assets/sass/**/*.scss', ['sass']); 

    n1.on('change', function(f) { 
     return gulp.src('./wp-content/themes/1/assets/sass/**/*.scss') 
      .pipe(sass.sync().on('error', sass.logError)) 
      .pipe(gulp.dest('./wp-content/themes/1/')); 
    }); 
    n2.on('change', function(f) { 
     console.log('Change Event:', f); 
     return gulp.src('./wp-content/themes/2/assets/sass/**/*.scss') 
      .pipe(sass.sync().on('error', sass.logError)) 
      .pipe(gulp.dest('./wp-content/themes/2/')); 
    }); 
    n3.on('change', function(f) { 
     return gulp.src('./wp-content/themes/3/assets/sass/**/*.scss') 
      .pipe(sass.sync().on('error', sass.logError)) 
      .pipe(gulp.dest('./wp-content/themes/3/')); 
    }); 
});
