使用一些常见的JS构建工具，例如Rollup.js，tsup等，bundle代码后运行，日志中即可看到报错信息。

webpack可以声明ue是外部模块，相信其它构建工具也会有类似的设置。

webpack可以声明ue是外部模块，相信其它构建工具也会有类似的设置。

确实可以声明是外部模块的，但是它们一般会作类似这样的操作：
dynamic import interop in rollup.js
在tsup中，确实也声明了外部模块，转换后的代码是commonjs的。比如，我把"ue"设置为外部模块后，它会转成直接调用require函数的代码：
image
目前我的方式是遵循这些打包器的习惯，设置了__esModule为true。

解决方案可参考 #1253
或者，当构建工具没有良好的配置选项时，参考本issue的思路也能避开这个问题，但做法并不符合ECMA规范。
