const source = from([1, 2, 3, 4]);
const example = source.pipe(filter(e => e % 2 === 0));
const multiple = example.pipe(map(e => e * e));
const subscribe = multiple.subscribe(
 e => console.log(e),
 error => console.log(error),
 () => console.log('结束啦!')

rxjs版本问题吧，https://rxjs-cn.github.io/learn-rxjs-operators/
