ios - Angular 5 应用程序无法在 ios8 (Browserstack) 中运行

Question

我已经在运行 IOS8 (Safari) 的 iPhone 6 和 Browserstack 中测试了我的 Angular 5 应用程序。 Angular 应用程序未运行，我只看到一个空白页面和此 Javascript 错误。

有什么建议吗？

这是我的 package.json 文件。我在想我在此处添加的某些包导致了一些冲突并阻止了应用程序的显示。以前我的应用程序能够在 IOS8 中运行，但那是在 Angular 4.4 中，我没有使用 mdbootstrap 库。

遇到了类似的问题。它应该通过提供正确的 polyfill 来解决。

您可以在此处找到浏览器支持信息 https://angular.io/guide/browser-support

如果您使用 JIT 编译器(而非 AOT)，那么 safari 至少需要 ES7 reflect polyfill。Safari 7 & 8 也需要 ES6

如果您仍然使用旧的基于 intl 的管道，那么不要忘记包含它们。

对于旧版浏览器，core-js/es/... 导入通常可以解决问题。

转到您的 src/polyfills.ts 并启用所需的 polyfill。

还有一个fetch polyfill在生成项目的readme中提到，polyfill.ts中没有。

导入“whatwg-fetch”；//运行 `npm install --save whatwg-fetch`
