Angular 6, rxjs 6 fork加入地图

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();

这里的剪辑不再适用于 rxjs 6：

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

我得到以下编译错误：

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.
    Type 'Observable<any>' is not assignable to type 'Observable<[string, string]>'.
      Types of property 'source' are incompatible.
        Type 'import("/Users/moritzvieli/node_modules/rxjs/internal/Observable").Observable<any>' is not assignable to type 'import("/Users/moritzvieli/repo/cltmgmtconsole/web/node_modules/rxjs/internal/Observable").Observ...'.

如何在 Angular 6 中映射一个 forkjoin？

Answer 1

我自己想通了：我从“rxjs/observable/forkJoin”而不是“rxjs”导入了错误的forkJoin。
