试过一些方法，比如存储路径用的绝对路径，都行不通，求解答

Answer 1

你的目录名过长，而且多级目录，是不是有点自己找苦吃，你确保这个目录存在吗？建议你简化目录结构并确保目录存在，如再不成功再发问题。有帮助请采纳！

Answer 2

用 you-get

Answer 3

能否发一下完整报错截图,
从如上报错来看是没找到对应文件夹
检测一下第一张图片是否成功下载,删除本地下载到的第一张图片重新跑一下试试有没有新报错,截图发一下上来

用相对路径修改了一下,运行的时候会在同目录下新建文件夹并存入

有帮助望采纳

Answer 5

你得问题，能不能截图完整

Answer 6

#a存储地址
a = 'C:/Users/TGananu/Desktop/下载/1.jpg'
#b存储名称为下载地址的简单处理（在名字末端加入‘-缩略图’）
b = 'C:/Users/TGananu/Desktop/下载/2.jpg'
#c存储地址
c = 'C:/Users/TGananu/Desktop/下载/3.jpg'

确保存储地址下有文件
如：a = 'C:/Users/TGananu/Desktop/下载/1.jpg'
先在目录 C:/Users/TGananu/Desktop/下载/ 下创建好jpg文件

Answer 7

在你用的字符串前面加一个r，你可以新建一个文件夹，os.chdir("路径"),全部下载到这个新的文件夹，然后再os.rename到你指定的文件夹，有用的话点一下采纳

Answer 8

应该是文件名问题，把那些符号去掉。

Answer 9

出现这种情况，首先查看目录是否有错，该目录文件是否存在。

其次在Python中“\”会被自动认为是转义字符，而非目录分隔符
