当我试图删除一个非空文件夹时,我得到一个“访问被拒绝”错误。我在尝试中使用了以下命令:os.remove("/folder_name")。

删除一个非空文件夹/目录最有效的方法是什么?


当前回答

它有助于删除包含所有文件和文件夹的目录

import os


def rrmdir(path):
    for entry in os.scandir(path):
        if entry.is_dir():
            rrmdir(entry)
        else:
            os.remove(entry)
    os.rmdir(path)

其他回答

删除一个文件夹,即使它可能不存在(避免Charles Chow回答中的竞态条件),但当其他事情出错时仍然有错误(例如权限问题,磁盘读取错误,文件不是目录)

对于Python 3.x:

import shutil

def ignore_absent_file(func, path, exc_inf):
    except_instance = exc_inf[1]
    if isinstance(except_instance, FileNotFoundError):
        return
    raise except_instance

shutil.rmtree(dir_to_delete, onerror=ignore_absent_file)

Python 2.7的代码几乎是一样的:

import shutil
import errno

def ignore_absent_file(func, path, exc_inf):
    except_instance = exc_inf[1]
    if isinstance(except_instance, OSError) and \
        except_instance.errno == errno.ENOENT:
        return
    raise except_instance

shutil.rmtree(dir_to_delete, onerror=ignore_absent_file)

您可以尝试下面的代码删除文件或文件夹,而不管它们是空的还是非空的。

import shutil
import os

directory = "path/to/the/root/folder"
files_in_directory = os.listdir(directory)

for file in files_in_directory:
    try:
        path_to_file_or_folder = os.path.join(directory, file)
        shutil.rmtree(path_to_file_or_folder)
    except:
        os.unlink(path_to_file_or_folder)

基于kkubasik的答案,在删除之前检查文件夹是否存在,更健壮

import shutil
def remove_folder(path):
    # check if folder exists
    if os.path.exists(path):
         # remove if exists
         shutil.rmtree(path)
    else:
         # throw your exception to handle this special scenario
         raise XXError("your exception") 
remove_folder("/folder_name")

在我的情况下,删除的唯一方法是使用所有的可能性,因为我的代码应该运行cmd.exe或powershell.exe。如果是你的情况,只需要用下面的代码创建一个函数就可以了:

        #!/usr/bin/env python3

        import shutil
        from os import path, system
        import sys

        # Try to delete the folder ---------------------------------------------
        if (path.isdir(folder)):
            shutil.rmtree(folder, ignore_errors=True)

        if (path.isdir(folder)):
            try:
                system("rd -r {0}".format(folder))
            except Exception as e:
                print("WARN: Failed to delete => {0}".format(e),file=sys.stderr)

        if (path.isdir(self.backup_folder_wrk)):
            try:
                system("rd /s /q {0}".format(folder))
            except Exception as e:
                print("WARN: Failed to delete => {0}".format(e),file=sys.stderr)

        if (path.isdir(folder)):
            print("WARN: Failed to delete {0}".format(folder),file=sys.stderr)
        # -------------------------------------------------------------------------------------

它有助于删除包含所有文件和文件夹的目录

    for entry in os.scandir(path):
        if entry.is_dir():
            rrmdir(entry)

            os.remove(entry)
    os.rmdir(path)
