Question

此代码片段在Angular 4中按预期工作：

Observable.forkJoin(
  Observable.of('test1'),
  Observable.of('test2')
).map(result => {
  console.log(result);
}).subscribe();

此片段在rxjs 6中不再起作用：

forkJoin(
  of('test1'),
  of('test2')
).pipe(map(result => {
  console.log(result);
})).subscribe();

我收到以下编译错误：

ERROR in app/services/bundles/karaf-bundles.service.ts(47,12): error TS2345: Argument of type 'OperatorFunction<[string, string], void>' is not assignable to parameter of type 'OperatorFunction<any, any>'.
  Types of parameters 'source' and 'source' are incompatible.

如何在Angular 6中映射forkjoin？

Answer 1

我自己弄清楚了：我从“ rxjs / observable / forkJoin”而不是“ rxjs”导入了错误的forkJoin。

Angular 6，rxjs 6 fork加入地图
