uniapp 白屏, 有点懵逼

三方 npm 包使用了不支持的扩展运算符 "..."，Android 上使用的 jscore 对 "..." 支持不完善

解决方案
配置 babel 显式转译
将 package.json 依赖的三方库加到 vue.config.js 节点 transpileDependencies: ['模块名称',...]

@DCloud_heavensoft

是语法层面的问题吗? 我要头大了, 在 ios 就没问题..
太奇怪了

机型和系统信息发一下

版本信息, 所有机型都报错, 老哥, 求解啊

暂时没有办法定位具体文件，可通过删除代码或在项目中搜索，展开对象的用法

(function() {  
    const a = {  
        a: 1,  
        b: 2  
    }  
    console.log({
