如何修复Windows下Reddit Meme爬虫的Error 13权限拒绝问题

我开发了一个从Reddit爬取meme并保存到指定目录的Python程序，但每次运行代码时，都会在meme应保存的指定目录出现Error 13权限拒绝错误，已花费3天时间排查此问题，恳请帮助。

我的代码 #

import os
import praw
import requests
from datetime import datetime

def downloadMemes():
    # 获取Reddit凭证
    r = praw.Reddit(client_id = 'iV5Qtn1sC7-AvS26PfYRJw', 
                         client_secret = '3ZMMo2kKwN0a0uG2mly6GnN8rSmkPQ', 
                         user_agent = 'ytbot')

    # 检查输出文件夹是否存在
    if os.path.exists("memes"):
        pass
    if not os.path.exists("memes"):
        os.mkdir("memes")

    if os.path.exists("newMemes"):
        pass
    if not os.path.exists("memes"):
        os.mkdir("newMemes")

    # 根据星期几选择子版块和帖子数量
    dt = datetime.now()
    day = dt.weekday()
    if day == 0:
        subreddit = r.subreddit('Memes')
        posts = subreddit.hot(limit=9)
    if day == 1:
        subreddit = r.subreddit('dankmemes')
        posts = subreddit.hot(limit=9)
    if day == 2:
        subreddit = r.subreddit('AnarchyChess')
        posts = subreddit.hot(limit=9)
    if day == 3:
        subreddit = r.subreddit('ProgrammerHumor')
        posts = subreddit.hot(limit=9)
    if day == 4:
        subreddit = r.subreddit('school_memes')
        posts = subreddit.hot(limit=9)
    if day == 5:
        subreddit = r.subreddit('wholesomememes')
        posts = subreddit.hot(limit=9)
    if day == 6:
        subreddit = r.subreddit('AnimalMemes')
        posts = subreddit.hot(limit=9)
    
    # 下载帖子
    for post in posts:
        url = (post.url)
        file_name = url.split("/")
        file_name = file_name[-1]
        print(file_name)
        r = requests.get(url)

        with open("memes/" + file_name,"wb") as f:
            f.write(r.content)

报错信息 #

已尝试的解决方法 #

• 替换过循环逻辑
• 在Linux虚拟机上运行程序，错误完全一致
