Gulp错误:您是否忘记了异步完成信号? [英] Gulp error: Did you forget to signal async completion?

问题描述

使用gulp编译简单脚本的问题.运行时会导致您是否忘记了异步完成信号?"错误.

Problems with compiling what I see as a simple script using gulp. When ran it causes a "Did you forget to signal async completion?" error.

在互联网上看，这似乎是异步函数的问题，请阅读传递并添加完成的函数可以解决此问题.就我而言，情况并非如此，所以想知道我在做什么错.

Looking at the internet this seems to be a problem with async functions and read that passing and adding the done function would resolve this. In my case this isn't the case so wondering what else I'm doing wrong.

gulp.task("compile-less", done => {
  gulp
    .src("./app/design/frontend/Playsports/theme_frontend_base/web/css/_base.less")
    .pipe(less())
    .pipe(
      gulp.dest(() => {
        return "./pub/static/frontend/Playsports/gcn/en_GB/css/";
      })
    );
  done();
});

gulp.task("default", done => {
  gulp.series("compile-less");
  done();
});

我希望这不会出错并完成任务.

I would expect this to not error and complete the task.

推荐答案

这将是一般形式:

gulp.task("default", gulp.series("compile-less", done => {
  // do something else here
  done();
}));

对于您而言，我认为这已经足够:

In your case I believe this is sufficient:

gulp.task("default", gulp.series("compile-less"));
