python-3.x - Python：PermissionError：[Errno 13] 与 windows 中的 copy_tree 函数

Question

我只是使用 Windows 中的函数 distutils.dir_util.copy_tree 从特定目录复制所有文件和子文件夹：

from distutils.dir_util import copy_tree
from datetime import datetime

directories_to_backup = {
    'folder_a' : 'e:\\folder_a',
}

now = datetime.now()
backup_name_folder = now.strftime("%Y%m%d-%H%M")

for name_folder, path_folder in directories_to_backup.items():
    print(f'Backuping up the folder {name_folder}')
    backup_full_path = f't:\\zzzBackup\\{backup_name_folder}\\{name_folder}\\'
    copy_tree(path_folder, backup_full_path)

它工作正常，直到它到达某个特定文件并出现以下错误：

Traceback (most recent call last):
  File "C:\Users\UserR\AppData\Local\Programs\Python\Python37\lib\distutils\file_util.py", line 48, in _copy_file_contents
    buf = fsrc.read(buffer_size)
PermissionError: [Errno 13] Permission denied

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

distutils.errors.DistutilsFileError: could not read from 'e:\folder_a\0\binlog': Permission denied

Process finished with exit code 1

如何更新 Windows 中的权限，以便我的脚本能够读取和复制文件？
