open 只能创建文件，不能创建文件夹，你需要在写文件前验证文件是否存在，如果不存在需要在写入前创建文件夹

import requests
import os  # 追加 os 引用

headers = {
    'Cookie': '_ga=GA1.2.1574857442.1641026894; _gid=GA1.2.607461508.1641026894; kw_token=WRFKXNRRLBB',

}
key = '薛之谦' #input('请输入要下载的歌手：')
pn = 1 #input('需要下载第几页：')

url = 'https://www.kuwo.cn/api/www/search/searchMusicBykeyWord?key={}&pn={}'.format(key,pn)
resp = requests.get(url, headers=headers)

# print(resp.json())

    rid = data['rid']

    # print(name)
    new_url = 'https://link.hhtjim.com/kw/{}.mp3'.format(rid)
    response = requests.get(new_url)
    if not os.path.exists('kuwo'): # 如果文件夹不存在则创建
        os.mkdir('kuwo')
    
    with open('kuwo/%s.mp3' % name, 'wb') as f:
        f.write(response.content)
        print(name, '下载成功')
