runsequence下面的代码是不是很有效?
var gulp = require('gulp');
var del = require('del');
var browserify = require('gulp-browserify');
var concat = require('gulp-concat');
var runSequence = require('run-sequence');
var nodemon = require('gulp-nodemon');
gulp.task('clean', function(cb) {
console.log('YOLO1');
del(['build/*'], cb);
});
gulp.task('copy', function() {
console.log('YOLO2')
return gulp.src('client/www/index.html')
.pipe(gulp.dest('build'));
});
gulp.task('browserify', function() {
console.log('YOLO3')
return gulp.src('client/index.js')
.pipe(browserify({transform: 'reactify'}))
.pipe(concat('app.js'))
.pipe(gulp.dest('build'));
});
gulp.task('build', function(cb) {
console.log('YOLO4')
runSequence('clean', 'browserify', 'copy', cb);
});
gulp.task('default', ['build'], function() {
gulp.watch('client/*/*', ['build']);
nodemon({ script: './bin/www', ignore: ['gulpfile.js', 'build', 'client', 'dist'] });
});
当前输出:
YOLO4,
YOLO1
渴望输出:
YOLO4,
YOLO1,
YOLO3,
YOLO2
我不确定为什么runSequence只执行第一个任务而无法执行其余任务?任何想法?

del
不接受回调,但会同步返回:(请参阅https://github.com/gulpjs/gulp/blob/master/docs/recipes/delete-files-folder.md中的第一个示例)
gulp.task('clean', function() {
console.log('YOLO1');
return del(['build/*']);
});
