gulp-babel 编译报错怎么解决？

Question

var gulp = require('gulp');
var babel = require('gulp-babel');

gulp.task('default', () => {
    return gulp.src('es6/index.js')
        .pipe(babel({
            presets: ['es2015']
        }))
        .pipe(gulp.dest('dist'));
});

刚开始编译时报：Couldn't find preset “es2015” relative to directory
然后安装了babel-preset-es2015
又报Couldn't find preset "react" relative to directory

请问这是什么原因？该如何解决

你项目工程下有 .babelrc 文件吗？ 检查下里面是否有重复设置
