我有以下几点

import logo from './logo.svg';
import './App.css';
import AppBar from '@mui/material/AppBar';
...
import axios from "axios";
import { useState, useEffect } from 'react';
...
function App() {
}

一切正常，但当我试着运行测试时，我得到...

({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,jest){import axios from './lib/axios.js';
                                                                                      ^^^^^^

    SyntaxError: Cannot use import statement outside a module

       5 | import Typography from '@mui/material/Typography';
       6 | import Box from '@mui/material/Box';
    >  7 | import axios from "axios";
         | ^

如果我删除Axios代码，一切正常，那么为什么导入失败呢？
