not working on node12 #41

在反复切换node版本后确定,只在node14上生效 node12上还是会报错

invalid expression: Unexpected token '.' in

    name?.value !== 1

是的，你说的没错。

我在MDN的文档上又确认了一遍，Node.js 对 optional chainig, nullish coalesing 语法的兼容性是从 V14 开始的：https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Optional_chaining#browser_compatibility

根本原因是：https://github.com/JuniorTour/vue-template-babel-compiler/issues/29#issuecomment-1005424023

临时优化方案是：“修改 package.json 中的 engine 字段到 >=14.0.0”

https://github.com/JuniorTour/vue-template-babel-compiler/blob/95ed545f0322ee106293835e9e37f92a1d934092/package.json#L12
