支付宝小程序

小程序基础库: 2.7.15
使用框架: React

复现步骤

1.使用以下命令构建cross-env NODE_ENV=test taro build --type alipay
2.获取构建产物打开调试工具
3.控制台报错
TypeError: Constructor Map requires 'new'
at ze.Map ()
at new ze (taro.js:2)
at Object. (taro.js:2)
at Object._ (taro.js:2)
at l (runtime.js:1)
at Module._ (app.js:2)
at l (runtime.js:1)
at t (runtime.js:1)
at Array.r [as push] (runtime.js:1)
at Object.GfhN (app.js:2)

期望结果

能正常运行

实际结果

taro运行时代码报错，导致小程序页面注册失败，无法打开页面

补充信息

初步排查，在Taro运行时代码里有一段event-source的逻辑，这里对Map进行了继承扩展并创建实例暴露出去。在测试环境打包构建压缩的时候，这里的实例化的动作括号丢失了，导致最终产物中这里没有进行实例化创建
// 源码
class EventSource extends Map {
removeNode (child: TaroNode) {
const { sid, uid } = child
this.delete(sid)
if (uid !== sid && uid) this.delete(uid)
}

removeNodeTree (child: TaroNode) {
this.removeNode(child)
const { childNodes } = child
childNodes.forEach(node => this.removeNodeTree(node))
}
}

export const eventSource: IEventSource = new EventSource()
// 构建产物
class ze extends Map {
removeNode(e) {
const {sid: t, uid: n} = e;
this.delete(t),
n !== t && n && this.delete(n)
}
removeNodeTree(e) {
this.removeNode(e);
const {childNodes: t} = e;
t.forEach(e=>this.removeNodeTree(e))
}
}
const He = new ze;
