Gulp任务编译babel

Question

完全披露我在Mean Stack Mundo中相当新，

我的gulp任务看起来像这样：

gulp.task('compile:babel', () => {
return gulp.src(['**/*.es6.js', '!node_modules/**'])
           .pipe(babel({optional: ['es7.decorators']}))
           .pipe(gulp.dest('.'));
})

当我通过命令行运行gulp时，我收到此错误：

C:\projects\BellaMusic\source>gulp
C:\projects\\BellaMusic\source\gulpfile.js:30
gulp.task('compile:babel', () => {
                        ^
SyntaxError: Unexpected token )

    at module.exports (C:\Users\Gizzmo\AppData\Roaming\npm\node_modules\gulp\node_modules\liftoff\node_modules\flagged-respawn\index.js:17:3)

我不知道造成这种情况的原因或在哪里开始任何想法都会非常感激。
