Javascript 清理任务后Gulp EN0ENT缺少目录错误？

我正在开始为一个项目学习吞咽。我想这是一个新手的错误，但我还没有弄明白

这是我的gulpfile.js：

这就是我收到的错误。每次我运行脚本时都会发生这种情况。接下来我运行它时，它工作正常。 冲洗，重复：

$ gulp
[23:15:50] Using gulpfile ~/Projects/test/gulpfile.js
[23:15:50] Starting 'default'...
[23:15:50] Starting 'clean'...
[23:15:50] Finished 'clean' after 644 μs
[23:15:50] Starting 'durp'...
[23:15:50] 'durp' errored after 26 ms
[23:15:50] Error: ENOENT: no such file or directory, stat './dist'
[23:15:50] 'default' errored after 29 ms

$ gulp
[23:15:51] Using gulpfile ~/Projects/test/gulpfile.js
[23:15:51] Starting 'default'...
[23:15:51] Starting 'clean'...
[23:15:51] Finished 'clean' after 431 μs
[23:15:51] Starting 'durp'...
[23:15:51] Finished 'durp' after 27 ms
[23:15:51] Finished 'default' after 30 ms

$ 

这很奇怪，因为我不希望出现比赛状态，因为我是在系列赛中跑步，而且不管怎样，清洁任务总是先跑。人力资源管理。

del不接受回调，但返回承诺。清洁功能应如下所示：

功能清洁{ 返回del'./dist'； } 您的durp任务在哪里被调用，什么是libguides？@thedancingcodeoops，libguides是一个工件；应该是杜普很晚了。
