Node.js 我得到；AssertionError[ERR_ASSERTION]：必须指定任务函数"；当我大口大口地跑的时候

在某些情况下，我试图为微软团队开发应用程序。因此，我决定遵循以下步骤，但在生成应用程序包（zip文件）时遇到了一个问题。我在Win10上

以下是我的node和gulp版本

$ gulp -v
CLI version: 2.2.0
Local version: 4.0.0

$ node -v
v12.14.1

我的错误：(

gulpfile.js

var gulp = require('gulp');
var zip = require('gulp-zip');
var del = require('del');

gulp.task('clean', function() {
    return del([
        'manifest/**/*'
    ])
});

gulp.task('generate-manifest', function() {
    gulp.src(['src/static/images/contoso*', 'src/manifest.json'])
        .pipe(zip('helloworldapp.zip'))
        .pipe(gulp.dest('manifest'));
});

gulp.task('default', ['clean', 'generate-manifest'], function() {
    console.log('Build completed. Output in manifest folder');
});

我读过其他一些文章，其中提到我必须降级节点并吞咽，但我运气不好

gulp.task('generate-manifest', function() {
    return gulp.src(['src/static/images/contoso*', 'src/manifest.json'])  // change here
        .pipe(zip('helloworldapp.zip'))
        .pipe(gulp.dest('manifest'));
});

gulp.task('default', gulp.series('clean', 'generate-manifest', function() {  // change here
    console.log('Build completed. Output in manifest folder');
}));

无需降级gulp或node。只需使用gulp4语法而不是gulp3

var gulp = require('gulp');
var zip = require('gulp-zip');
var del = require('del');

gulp.task('clean', function() {
    return del([
        'manifest/**/*'
    ])
});

gulp.task('generate-manifest', function() {
    gulp.src(['src/static/images/contoso*', 'src/manifest.json'])
        .pipe(zip('helloworldapp.zip'))
        .pipe(gulp.dest('manifest'));
});

gulp.task('default', ['clean', 'generate-manifest'], function() {
    console.log('Build completed. Output in manifest folder');
});

gulp.task('generate-manifest', function() {
    return gulp.src(['src/static/images/contoso*', 'src/manifest.json'])  // change here
        .pipe(zip('helloworldapp.zip'))
        .pipe(gulp.dest('manifest'));
});

gulp.task('default', gulp.series('clean', 'generate-manifest', function() {  // change here
    console.log('Build completed. Output in manifest folder');
}));
