我正在使用一个react挂钩通过axios从covid api获取数据,但是它抛出了一个错误
React Hook useEffect has a missing dependency: 'countries'. Either include it or remove the dependency array react-hooks/exhaustive-deps

import axios from 'axios';
import { useEffect, useState } from '

我正在尝试使用jest.spyOn()代替jest.mock进行测试,因为mock的返回值不能进行类型检查。但是,当我使用它时,我得到以下错误:

我尝试在useEffect中更新数据,但在控制台中显示警告。
