Gulp error - "ReferenceError: series is not defined"

Question

我在这一行收到这个引用错误：

gulp.watch(paths.src.html, series(copyHtml, browserSyncReload));

我不知道如何解决这个问题。有什么建议吗？

gulpfile.js

// BrowserSync
function browserSync(done) {
    browsersync.init({
        open: false,
        server: {
            baseDir: paths.dist.base
        },
    });
    done();
}

// BrowserSync Reload
function browserSyncReload(done) {
    browsersync.reload();
    done();
}

// Watch files
function watchFiles() {
    gulp.watch(paths.src.html, series(copyHtml, browserSyncReload));
    gulp.watch("./tailwind.js", css);
    gulp.watch(paths.src.js, series(minifyJs, browserSyncReload));
}

// Complex tasks
const build = gulp.series(clean, css, minifyCss, minifyJs, purgeCSS);
const watch = gulp.parallel(watchFiles, browserSync);

exports.build = build;
exports.default = watch;

使用 gulp.series 修复它：

gulp.watch(paths.src.html, gulp.series(copyHtml, browserSyncReload));
