Visual studio code 不能吞咽

我如何解决这个问题？我正在使用VSCode并试图在我的项目中安装gulp。这有什么问题

SyntaxError: Cannot use import statement outside a module
    at Module._compile (internal/modules/cjs/loader.js:895:18)
    at Object.Module._extensions..js (internal/modules/cjs/loader.js:995:10)
    at Module.load (internal/modules/cjs/loader.js:815:32)
    at Function.Module._load (internal/modules/cjs/loader.js:727:14)
    at Module.require (internal/modules/cjs/loader.js:852:19)
    at require (internal/modules/cjs/helpers.js:74:18)

gulpfile.js

import { src, dest } from 'gulp';
import sass from 'gulp-sass';
import minifyCSS from 'gulp-csso';


function style() {
    return src('./scss/**/*.scss')
        .pipe(sass())
        .pipe(minifyCSS())
        .pipe(dest('./css'))
}

const _style = style;
export { _style as style };

终端代码：gulp_风格

节点——实验模块gulpfile.js及其工作后 并将gulpfile.js更改为此类型

const gulp = require('gulp');
const sass = require('gulp-sass');
const minifyCSS = require('gulp-csso');


function style() {
    return gulp.src('./scss/**/*.scss')
        .pipe(sass())
        .pipe(minifyCSS())
        .pipe(gulp.dest('./css'))
}

exports.style = style;
