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没有提供更新的原理图

Answer 1

将以下内容添加到polyfills.ts

{{1}}

Answer 2

在此问题得到解决之前有一种解决方法，

尝试在index.html head标记中添加以下内容

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

Answer 3

ReferenceError：未定义global

修复

来自https://github.com/angular/angular-cli/issues/9920：Node shims have been removed in 6.0

解决方案：破解的代码就是问题所在。至少那是角度的立场。例如。向aws-sdk等报告

Answer 4

根据本文档（并由我测试）：https://aws-amplify.github.io/amplify-js/media/angular_guide

您只需要将此行添加到顶部的polyfills.ts文件中：

这应该可以修复它，并且是正确的方法。
