找不到变量：Safari中的BigInt64Array

问题描述

最近，我的Angular 8网络应用程序停止在Safari上运行（停留在index.html页面上）。它在调试器中引发错误，指出：找不到变量：BigInt64Array 我没有通过npm升级任何东西，所以我不确定为什么突然开始发生这种情况。 我尝试将tsconfig.js中的target从“ es2015”更改为“ ES5”。我也将Safari >= 10添加到了我的浏览器列表中，但是没有运气。 有任何想法吗？ 谢谢！

解决方法

结果是"deep-copy-ts": "^0.5.0",是问题所在。该软件包需要BigInt64Array，这是Safari上的重大更改。删除后，它便开始工作。
