angular - Observable.zip 不是函数

Question

VM95422:27 ORIGINAL EXCEPTION: WEBPACK_IMPORTED_MODULE_3_rxjs_Observable.Observable.zip is not a function

尝试了各种导入

// import 'rxjs/add/operator/zip';
// import 'rxjs/add/observable/zip-static';
// import 'rxjs/add/operator/zip';
import 'rxjs/operator/zip';

尝试像那样使用它:

const zippedUsers: Observable<User[]> = Observable.zip<User>(this.usersObservable);

Angular 4， typescript 2.1.6

package.json:

"rxjs": "^5.1.0",

Answer 1

也许是这样的

import {Observable} from "rxjs/Observable";
import "rxjs/add/observable/zip";

然后是这样的:

Observable.zip(this.someProvider.getA(), this.someProvider.getB())
        .subscribe(([a, b]) => {
            console.log(a);
            console.log(b);
        });
