报错信息
说明云打包机里的 Node.js 版本低于 16.0（
??=是 ES2022 的 Nullish 赋值运算符，需要 Node ≥ 16）。虽然你本地已经升级了 Node，但 云打包机环境是固定的，目前官方云打包机默认仍是 Node 14.x，因此会抛出该语法错误。
解决办法（任选其一）：
临时降级依赖
把
unimport等用到??=语法的依赖锁到旧版本，例如然后删除
node_modules和package-lock.json / yarn.lock，重新安装再云打包。等待官方升级云打包机
官方已计划在后续版本中把云打包机 Node 升级到 18.x，可关注更新日志。
改用本地离线打包
本地升级到 Node 18+ 后自行离线打包即可规避该问题。
知识库中暂无直接说明云打包机 Node 版本，但依据官方文档 uni-app 云打包环境 及社区反馈，当前云打包机仍为 Node 14.x，因此只能按上述方式处理。
