"babel-cli": "^6.26.0",
 "babel-core": "^6.26.3",
 "babel-preset-es2015": "^6.24.1",
"gulp-babel": "6",

如上代码所示，安装以上版本的babel插件，bable更新很快，当版本不一致会冲突，导致出现  Plugin/Preset files are not allowed to export objects, only functions   。

gulp压缩js代码如下

const uglify = require('gulp-uglify'); //js压缩
const babel = require("gulp-babel");


// gulp打包manager\page\dist\js
gulp.task('revJs',  ()=> {
    return gulp.src([filePath + '/page/dist/js/*.js'])
    .pipe(babel({//编译ES6
        presets: ['es2015']
    }))
    .pipe(uglify())//压缩js   
        .pipe(gulp.dest( 'dist/manager/page/dist/js'))
})
