import error
import { CacheSwitch, CacheRoute } from 'react-router-cache-route';

import error import { CacheSwitch, CacheRoute } from 'react-router-cache-route';

import CacheRoute, { CacheSwitch } from 'react-router-cache-route'文档不是这样写的吗？

import error import { CacheSwitch, CacheRoute } from 'react-router-cache-route';

大佬在哪找到的解决办法？
