找不到变量: Safari中的BigInt64Array

Question

就在最近，我的Range8web应用程序停止了Safari (卡在index.html页面上)的工作。它在调试器中抛出一个错误，声明：找不到变量:BigInt64Array，，我没有通过npm升级任何东西，所以我不知道为什么突然开始发生这种情况。我尝试将target从tsconfig.js中的"es2015“改为”es2015“。我还将Safari >= 10添加到浏览器列表中，但没有运气。有什么想法吗？谢谢!

事实证明，"deep-copy-ts": "^0.5.0",是问题所在。这个包需要BigInt64Array，是Safari上的重大变化。一旦移除它就开始工作了。
