javascript - 我该如何解决这个错误 'The following tasks did not complete: default, Did you forget to signal async completion? '

Question

这是我的 gulpfile.js

const gulp = require('gulp');
gulp.task('default', function () {
});

我在终端中写入gulp响应是..

[19:47:02] Using gulpfile D:\DEV64\LearningJS\gulpfile.js

[19:47:02] Starting 'default'...

[19:47:02] The following tasks did not complete: default

[19:47:02] Did you forget to signal async completion?

我能做什么？

Answer 1

在 Gulp 3.x 中，您不需要发出完成信号。但从 Gulp 4.x 开始，您需要这样做。

Gulp 自动将回调函数作为其第一个参数传递给您的任务。在您的情况下，简单的方法是调用回调。

gulp.task('default', function(done) {
  console.log("Started");
  done();
});
