如果使用的节点版本高于6.x.x。尝试以下代码。它将解决此问题。

def dedup(lst):
    mx = max(lst) + 1
    dupcnt = 0
    delcnt = 0
    start = 0
    for i in range(1, len(lst) + 1):
        if i == len(lst) or (lst[i] != lst[start]):
            lst[start - delcnt] = lst[start] + dupcnt * mx
            delcnt += dupcnt
            start = i
            dupcnt = 0
        else:
            dupcnt += 1
    dupidx = len(lst) - delcnt
    for i in range(0, len(lst) - delcnt):
        dupcnt = lst[i] // mx
        if dupcnt:
           lst[i] %= mx
           for j in range(dupidx, dupidx+dupcnt):
              lst[j] = lst[i]
           dupidx += dupcnt
    return lst

print(dedup([1,2,2,2,3,4,4,5]))
>>> [1, 2, 3, 4, 5, 2, 2, 4]

Answer 2

从此包路径导入Observable：

import { Observable } from 'rxjs/Observable';

Answer 3

如果您使用的是角度版本6，则可以使用

//创建和实用方法

import { Observable, Subject, pipe } from 'rxjs';

//运算符都来自rxjs /运算符

import { map, takeUntil, tap } from 'rxjs/operators';
