我将 rxjs 更新到 6.1.0。而且我想将我的导入重构为新样式。我是说：

import { Observable, of } from 'rxjs';

但这给了我一个错误：

// return Observable.of(data); 
error TS2339: Property 'of' does not exist on type 'typeof Observable'.

地图导入工作（我认为）

import { map } from 'rxjs/operators';

return this.http.post(url, data).pipe(
    map(res => res)
)

我该怎么办？

我还附加了我的依赖项

"@angular/animations": "^6.0.0",
"@angular/common": "^6.0.0",

之前 

 import 'rxjs/add/observable/of';
    // or 
    import { of } from 'rxjs/observable/of
const source = Observable.of(1, 2, 3, 4, 5);

    const subscribe = source.subscribe(val => console.log(val));

在 RXJS:6 中，语法也发生了变化，也导入了而不是Observable.of使用of

import { Observable, of } from 'rxjs';

const source = of(1, 2, 3, 4, 5);

const subscribe = source.subscribe(val => console.log(val));

现在是：

import { of } from 'rxjs/observable/of';
