Question

这是我的gulp脚本。我没有任何问题。但我改变了配置。当我跑这个时我得到了错误。＆＃39;合并复制组件＆＃39;任务不起作用。为了使其工作，我必须执行上一个任务。但我认为任务不会执行和完成，但与后来的任务同时工作。

我该如何解决这个问题？我想同步完成两项任务。

  var gulp = require('gulp'),
  //usemin = require('gulp-usemin'),
  wrap = require('gulp-wrap'),

创建任务：

gulp.task('filet', function() {
  gulp.src('src/components/**/*.*') 
      .pipe(gulp.dest('../admin/assets/components'));
 });

然后将其添加到您的另一个任务的依赖项

gulp.task('merge-copy-components', ['filter'], function() {
...

这将确保＆＃39;过滤＆＃39;任务在＆merge-copy-components＆＃39;。

如何在gulp中同步完成任务？
