【中文标题】更新到 Angular 6 和 rxjs 6 后 Plunker 坏了【英文标题】：Plunker broken after updating to Angular 6 and rxjs 6 【发布时间】：2018-12-19 15:49:09 【问题描述】：我有一个 Angular app in Plunker，因为我已经升级我的应用程序以使用 Angular 6 和 rxjs 6，所以它不再工作了。
这是我的config.js 文件：
var angularVersion;
if(window.AngularVersionForThisPlunker === 'latest')
angularVersion = ''; //picks up latest
else
angularVersion = '@' + window.AngularVersionForThisPlunker;
System.config(
//use typescript for compilation
transpiler: 'typescript',
//typescript compiler options
typescriptOptions:
emitDecoratorMetadata: true
,
paths:
'npm:': 'https://unpkg.com/'
,
//map tells the System loader where to look for things
map:

);
现在我收到这些错误：

【问题讨论】：
【参考方案1】：更换
rxjs:
defaultExtension: 'js'
,
与
rxjs:
main: 'index.js',
defaultExtension: 'js'
,
"rxjs/operators":
main: 'index.js',
defaultExtension: 'js'
,
为我工作
【讨论】：
【参考方案2】：我已经通过修改我的config.js 解决了如下问题：
var angularVersion;
if(window.AngularVersionForThisPlunker === 'latest')
angularVersion = ''; //picks up latest
else
angularVersion = '@' + window.AngularVersionForThisPlunker;

如果能描述解决问题的更改，那就太好了。否则我们将不得不做一个差异来找出解决问题的变化。以上是关于更新到 Angular 6 和 rxjs 6 后 Plunker 坏了的主要内容，如果未能解决你的问题，请参考以下文章
在 Angular 6 中选择带有 RxJS 的状态不起作用
