麻烦解答下, 谢谢哈🙈

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',...]

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({
        ...a
    })
})();

麻烦问下, 造成这种错误只是第三方包 npm 包吗? 我本地也用了 ... 展开运算符

谢谢

d1y commented 4 years ago

我将可疑的几个 npm 包丢在了 vue.config.js 的 transpileDependencies

然而还是报错, 我生成了本地的打包app资源, 然后搜索 ..., 结果

代码片段(app-service.js): https://note.ms/ijbi

有点迷了, 貌似加 transpileDependencies 好像没有成功

不过特别奇怪的是, 我用调试服务, 就可以运行不报错了

fxy060608 commented 4 years ago

1.把normalize-url也加到transpileDependencies里边 2.调试期间，js代码运行在pc端，与真机运行环境不同

一直都是很正常的，今天是在没有任何更改第三方包的情况下，突然报这个错误了
