Gulp error: The following tasks did not complete: default, sass

Question

我已经为我正在构建的项目创建了一个 gulpfile.js 文件。当我尝试运行它时，出现此错误。

[18:29:03] Using gulpfile ~\Documents\codeprojects\antenna\gulpfile.js
[18:29:03] Starting 'default'...
[18:29:03] Starting 'sass'...
[18:29:03] The following tasks did not complete: default, sass
[18:29:03] Did you forget to signal async completion?

这是我的 gulpfile.js 代码

var gulp = require('gulp');
var sass = require('gulp-sass');
var plumber = require('gulp-plumber');

gulp.task('sass', function() {
    gulp.src('public/stylesheets/style.scss')
      .pipe(plumber())
      .pipe(sass())
      .pipe(gulp.dest('public/stylesheets'));
});

gulp.task('watch', function() {
    gulp.watch('public/stylesheets/*.scss', ['sass']);
});

gulp.task('default', gulp.series('sass', 'watch'));

Answer 1

gulp.task('sass', function() {
    return gulp.src('public/stylesheets/style.scss')  // return added here
      .pipe(plumber())
      .pipe(sass())
      .pipe(gulp.dest('public/stylesheets'));
});

// the return above will suffice to "signal async completion"

gulp.task('watch', function() {
    // gulp.watch('public/stylesheets/*.scss', ['sass']);  // old gulp v3 synatx
    gulp.watch('public/stylesheets/*.scss', gulp.series('sass'));  // v4 syntax
});

此外，您需要切换到插件 gulp-dart-sass 而不是 gulp-sass。它支持更新的功能，例如 @use。
