【问题描述】：
IE 中的错误： vendor.js (82613,35)
const emitsWrappingTags = (node) => {
return !!node.kind;
};
基本上说IE不知道箭头函数是什么。

我已经为他们看到了多个类似的问题和解决方案，但没有一个适用于我的项目。 无论上述设置如何，Typescript 都会编译为 es6。我猜它与节点包有关，但找不到。
【问题讨论】：
-
那你的
tsconfig.app.json目标可能在那里被覆盖了？ -
很遗憾没有。我已经添加了 tsconfig.app.json 来发帖。
-
啊，但是它来自
vendor.js，这意味着它来自一个已经编译好的第三方库。你应该找出哪个是:)
