Question

我正在使用此“初学者指南”指南：https://css-tricks.com/gulp-for-beginners/

这是我的gulpfile.js：

var gulp = require('gulp');
// Requires the gulp-sass plugin
var sass = require('gulp-sass');


gulp.task('sass', function() {
  return gulp.src('sass/**/*.sass') // Gets all files ending with .sass in /sass
    .pipe(sass())
    .pipe(gulp.dest('css'))
});


gulp.task('watch', ['sass'], function (){
  gulp.watch('app/scss/**/*.scss', ['sass']); 
});

我只想让Gulp正常工作，但是我不确定我的本地环境设置是否不正确，我不知道该怎么办。

要么我的gulpfile编写不正确，要么我担心macbook出现问题，因为我一直在努力使gulp，咕unt声或其他cli东西无法正常工作。

我的终端窗口：

$ gulp watch
assert.js:350
    throw err;
    ^

AssertionError [ERR_ASSERTION]: Task function must be specified

    at require (internal/modules/cjs/helpers.js:22:18)

GulpFile向我抛出错误：AssertionError [ERR_ASSERTION]：必须指定任务功能
