我想将src文件夹编译到build文件夹中，但是gulp-babel没有创建任何文件，并且看不到任何错误。
gulp.task('build', () => {
gulp
.src(['./src/**/*.js'])
.pipe(
babel({
presets: ['@babel/preset-env']
})
)
.pipe(gulp.dest('build/'))
})
日志：
[10:52:18] Starting 'build'...
[10:52:18] Finished 'build' after 5.85 ms
我的SCSS文件有相似的源和目标，并且可以完美运行，所以据我所知这不是路径问题。
