我尝试使用shutil删除一个目录及其内含的所有文件，如下所示：
import shutil
from os.path import exists
if exists(path_dir):
shutil.rmtree(path_dir)
很遗憾，我的解决方案不起作用，会抛出以下错误：
FileNotFoundError: [Errno 2] No such file or directory: '._image1.jpg'
快速搜索显示我在遇到该问题时并不孤单。
据我所知，rmtree函数相当于rm -Rf $DIR shell命令，但实际上并非如此。
p.s.为了重建目的，请使用ln -s /path/to/original /path/to/link来创建符号链接示例。
很奇怪，我在删除文件夹时使用shutil.rmtree() 无论是在包含软链接的还是不包含软链接的情况下都没有问题，在Windows 10和Ubuntu 20.04.2 LTS上都可以正常工作。
不过你可以尝试下面的代码，我已经在Windows 10和Ubuntu上测试过了。
from pathlib import Path
import shutil
def delete_dir_recursion(p):
"""
Delete folder, sub-folders and files.
"""
for f in p.glob('**/*'):
if f.is_symlink():
f.unlink(missing_ok=True) # missing_ok is added in python 3.8
print(f'symlink {f.name} from path {f} was deleted')
elif f.is_file():
f.unlink()
print(f'file: {f.name} from path {f} was deleted')
elif f.is_dir():
try:
f.rmdir() # delete empty sub-folder
print(f'folder: {f.name} from path {f} was deleted')
except OSError: # sub-folder is not empty
delete_dir_recursion(f) # recurse the current sub-folder
except Exception as exception: # capture other exception
print(f'exception name: {exception.__class__.__name__}')
print(f'exception msg: {exception}')
try:
p.rmdir() # time to delete an empty folder
print(f'folder: {p.name} from path {p} was deleted')
except NotADirectoryError:
p.unlink() # delete folder even if it is a symlink, linux
print(f'symlink folder: {p.name} from path {p} was deleted')
except Exception as exception:
print(f'exception name: {exception.__class__.__name__}')
print(f'exception msg: {exception}')
def delete_dir(folder):
p = Path(folder)
if not p.exists():
print(f'The path {p} does not exists!')
return
# Attempt to delete the whole folder at once.
try:
shutil.rmtree(p)
except Exception as exception:
print(f'exception name: {exception.__class__.__name__}')
print(f'exception msg: {exception}')
# continue parsing the folder
else: # else if no issues on rmtree()
if not p.exists(): # verify
print(f'folder {p} was successfully deleted by shutil.rmtree!')
return
print(f'Parse the folder {folder} ...')
delete_dir_recursion(p)
if not p.exists(): # verify
print(f'folder {p} was successfully deleted!')
# start
folder_to_delete = '/home/zz/tmp/sample/b' # delete folder b
delete_dir(folder_to_delete)
输出结果示例：
我们将要删除文件夹b。

p.rmdir() # time to delete an empty folder 中处理。是否有任何消息？您是在Linux还是Windows上进行测试？ - ferdy._ 为前缀的二进制补充文件，记录所谓的扩展属性（在https://apple.stackexchange.com/questions/14980/why-are-dot-underscore-files-created-and-how-can-i-avoid-them中有解释，也在下面说明）。os.scandir 中的文件描述符的系统（如 Mac OSX），rmtree 现在不安全地创建一个条目列表，然后逐个删除它们（创建已知的竞争条件：https://github.com/python/cpython/blob/908fd691f96403a3c30d85c17dd74ed1f26a60fd/Lib/shutil.py#L592-L621）。不幸的是，两种不同的行为使得这个条件每次都成立：
test.txt）时，元文件（._test.txt）同时被删除。FileNotFoundError。rmtree 中的 FileNotFoundError。
onerror 忽略这些元文件上的删除错误：def ignore_extended_attributes(func, filename, exc_info):
is_meta_file = os.path.basename(filename).startswith("._")
if not (func is os.unlink and is_meta_file):
raise
shutil.rmtree(path_dir, onerror=ignore_extended_attributes)
为了说明，您可以创建一个小型的ExFAT磁盘映像，并使用以下命令将其挂载到/Volumes/Untitled：
hdiutil create -size 5m -fs exfat test.dmg
hdiutil attach test.dmg # mounts at /Volumes/Untitled
cd /Volumes/Untitled
mkdir test # create a directory to remove
cd test
touch test.txt
open test.txt # open the test.txt file in the standard editor
在标准文本编辑器中打开文件会创建一个扩展属性文件._test.txt，并记录最后访问时间：
/Volumes/Untitled/test $ ls -a
. .. ._test.txt test.txt
/Volumes/Untitled/test $ xattr test.txt
com.apple.lastuseddate#PS
/Volumes/Untitled/test $ rm test.txt
/Volumes/Untitled/test $ ls -a
. ..
# function that deletes all files and then folder
import glob, os
def del_folder(dir_name):
dir_path = os.getcwd() + "\{}".format(dir_name)
try:
os.rmdir(dir_path) # remove the folder
except:
print("OSError") # couldn't remove the folder because we have files inside it
finally:
# now iterate through files in that folder and delete them one by one and delete the folder at the end
try:
for filepath in os.listdir(dir_path):
os.remove(dir_path + "\{}".format(filepath))
os.rmdir(dir_path)
print("folder is deleted")
except:
print("folder is not there")
ignore_errors标志与shutil.rmtree()一起使用。
shutil.rmtree('/folder_name', ignore_errors=True)
这将删除一个包含文件内容的目录。
path_dir是一个符号链接的路径吗？ - gimix
