你是直接引用的我的 ES6 模块吗？如果是，添加以下这个插件:@babel/plugin-transform-optional-chaining

` /**

• babel.config.js - Babel 工程配置
• =============================================================
• Created By: Yaohaixiao
• Update: 2023.2.27 */ module.exports = { presets: [['@babel/preset-env']], plugins: [ // 配置“可选链操作符”（babel插件） '@babel/plugin-transform-optional-chaining', '@babel/plugin-transform-spread', '@babel/plugin-transform-object-rest-spread' ], assumptions: { arrayLikeIsIterable: true } } `

应该可以确定是你的项目没有配置 配置“可选链操作符”（babel插件） 的解析插件的问题了
