Angular 2，iOS Safari 错误：eval@[native code]答案

【问题标题】：Angular 2, iOS safari Error: eval@[native code]Angular 2，iOS Safari 错误：eval@[native code]

【问题描述】：

我有一个 node/express/angular 2 应用程序。在桌面 safari/chrome 中加载应用程序就可以了。没有错误。但是，如果我尝试将其启动到 iOS Safari 移动浏览器中，我会收到：

Error: eval@[native code]

不太确定这是否是一些加载问题？还是兼容性问题？ index.hbs

【解决方案1】：

您的 tsconfig.json 中是否有 es6 作为目标？如果将其更改为 es5，它应该可以工作。不幸的是，对 es6 的 Safari 支持非常糟糕。我尝试使用 core-js shim，但也没有用。

如果你还想使用 Promise 之类的功能，你必须添加...

"files": [
  "../node_modules/typescript/lib/lib.es6.d.ts" 
],
"include": [
   "./*.*.ts" // where ever your typescript files are
]

...到你的 tsconfig 也是如此。这对我有用。
