npm run prod 错误：SyntaxError: Unexpected token = at new Script (vm.js:83:7)

如何解决npm run prod 错误：SyntaxError: Unexpected token = at new Script (vm.js:83:7)

我需要在 Laravel 应用程序上运行 npm run prod 但出现错误：

SyntaxError: Unexpected token = at new Script (vm.js:83:7)

操作系统是 Ubuntu 20,04 节点版本是 15.12.0 npm 版本 7.7.5。

有 known issue on Ubuntu 20,04 because of node version 10 但我升级了还是一样。也试过 node -v 15.2

> npm run production    

> production
> mix --production
