aws-sdk:从angular5更新为angular6后崩溃

Question

我刚从Angular 5.2更新到Angular 6.0,我的代码现在突破了这个错误:

core.js:1601 ERROR Error: Uncaught (in promise): ReferenceError: global is 
not defined
ReferenceError: global is not defined

有人知道这个问题吗？我尝试过更新,但似乎aws-sdk-js不提供更新的原理图

Answer 1

将以下内容添加到polyfills.ts中

// aws-sdk requires global to exist
(window as any).global = window;

Answer 2

在解决此问题之前有一个解决方法，

尝试在您的 index.html head 标签中添加以下内容

<script>
  if (global === undefined) {
    var global = window;
  }
</script>
