问题描述
我正在尝试使用 Python 2.7 在 Windows 上复制文件，但有时会失败.
I am trying to copy files on Windows with Python 2.7, but sometimes this fails.
shutil.copyfile(copy_file, dest_file)
我收到以下 IOError:
I get the following IOError:
[Errno 2] No such file or directory
但是文件确实存在！问题是文件的路径太长.(> 255 个字符)
But the file does exist! The problem is that the path of the file is too long. (> 255 characters)
如何复制这些文件?在其他应用程序中打开它们不是问题.
How do I copy these files? It isn't a problem to open them in other applications.
要创建路径过长的文件，请创建一个文件名尽可能长的文件，并将包含的文件夹移到树结构的更深处.
To create a file with a too long path, create a file with an as long as possible file name and move the containing folder deeper down a tree structure.
我一直在尝试其中一些方法但没有成功:http://timgolden.me.uk/python/win32_how_do_i/copy-a-file.html

推荐答案
我不确定 255 字符的限制，所以我偶然发现了 这篇文章.在那里我找到了一个可行的答案:在路径之前添加 \?.
I wasn't sure about the 255 char limit so I stumbled on this post. There I found a working answer: adding \? before the path.
shutil.copyfile("\\?\" + copy_file, dest_file)
我发现使用长路径会导致 Windows 出现问题.我使用的另一个技巧是缩短路径:
edit: I've found that working with long paths causes issues on Windows. Another trick I use is to just shorten the paths:
import win32api
path = win32api.GetShortPathName(path)
