Question

我正在使用gulp将javascript / css文件复制到dist文件夹。有时它可以工作，但有时2个任务仍未完成。我以为这是一个时序问题，所以我已经安装了运行顺序，但是即使那样，并且.on（'end'）回调我的代码似乎也不起作用。所以我可能一直想念其他东西。

function errorHandler(error) {

错误日志保持空白，因此我不知道在哪里查找。

任何想法都将不胜感激。干杯！

您必须在任务中返回流，而不仅仅是从任务结束处返回。参见signal task completion及其中的示例。

当流，promise，事件发射器，子进程或可观察对象为从任务返回时，成功还是错误通知gulp是否继续或结束。

所以

gulp.task('clean', function () {
  return gulp.src('./client/dist/*')
    .pipe(clean({ force: true }));

  // return;
});

对所有任务进行更改。

大吃一惊，一些任务未完成
