尝试使用 xlrd 或 shutil 访问文件夹中的文件时出现权限被拒绝问题 [英] permission denied issue when trying to access files in a folder with xlrd or shutil

问题描述

我删除了它，但我将取消删除，因为我认为它可能有用.并发布我当时没有意识到的实际发生的事情.

原始问题:我正在尝试打开一组 excel 文件，其中一个文件当前由另一个用户打开.所有其他文件都有效，但我收到权限被拒绝"错误.

Original Question: I'm trying to open a set of excel files where one is currently open by another user. All of the other files work, but this one I get 'permission denied' errors.

Windows 为您提供了只读"打开文件的选项，但我似乎无法在 python (xlrd) 中找到等效项，因此我想我会将文件复制到临时位置并打开它；但这也不起作用.无论哪种情况，我都会得到:

Windows gives you the option to "read only" open the file, but I can't seem to find an equivalent in python (xlrd), so I thought I would copy the file to a temp location and open it; but that doesn't work either. In either case, i get:

IOError: [Errno 13] Permission denied:

是否可以:

• 在 xlrd 中以只读模式(如 windows)打开一个 excel 文件
• 复制另一个用户当前正在使用的文件

谢谢！

推荐答案

事实证明，我失败的文件也被其他用户打开，所以当我通过 Windows 资源管理器访问它们时，另一个用户似乎很自然打开文件会导致权限被拒绝错误；然而，真正的问题是，当我在文件夹中循环时，我试图访问 Excel 为访问该文件的其他用户创建的临时文件.

As it turns out, I the files that were failing were also open by other users, so when I went to access them through windows explorer it seemed natural another user having the file open would cause the permission denied error; however the real issue is that as I was looping through the folder I was attempting to access the temp files created by Excel for the other user who was accessing the file.

因此，对于用户打开的给定文件old_file.xlsx"，他们的 excel 实例创建了~$old_file.xlsx"

So, for a given file "old_file.xlsx" that a user had open, their instance of excel created "~$old_file.xlsx"

我是如何解决这个问题的:

How I got around this was:

files_to_check = [f for f in os.listdir(PATH) if os.path.isfile(f)]
files_to_check = [f for f in files_to_check if '~' not in f and 'xlsx' in f]

基本上，只要确保它们是我计划通过的非临时 xlsx 文件.

basically, just making sure that they're the non-temp, xlsx files that I planned to go through.
