使用方法

　　将代码复制到本地 python 的 ide 中，
　　修改 第五行的mod 为要下载的包
　　修改 第六行version 为包的版本
　　运行即可

环境说明
　　需要 requests 依赖包 如果没有 pip install requests

代码

import requests, re, os, time, shutil

url = "https://unpkg.com/"

mod = "axios"
version = "0.21.4"

headers = {'Accept-Language': 'zh-CN,zh;q=0.8',

        else:

    return {"files": files, "folders": folders}


# 创建目录

    else:
        print("文件已存在")
