Question

我有一个节点/ express / angular 2 app。在桌面safari / chrome中加载应用程序就可以了。没有错误。但是，如果我然后尝试将其启动到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

你的tsconfig.json中有es6作为目标吗？如果将其更改为es5，它应该可以工作。不幸的是，es6的Safari支持非常糟糕。我尝试使用core-js垫片，但这也没有用。

如果你仍想使用像Promise这样的超棒，你必须添加......

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

...也是你的tsconfig。这对我有用。
