我有一个压缩的 .zip 文件,我想将其转换为未压缩的 .tar 文件。
我做了这个功能来做到这一点:
def decompress(filepath):
devname = re.search("_(.+?)_.+?\.zip", filepath).group(1)
with zipfile.ZipFile(filepath, 'r') as zip:
path = os.path.join(start_dir, "Downloads", devname, str(os.path.basename(filepath))[:-4])
zip.extractall(path)
with tarfile.open(path + ".tar", 'w') as tar:
for object in os.listdir(path):
tar.add(os.path.join(path, object), arcname=object)
time.sleep(2)
shutil.rmtree(path, ignore_errors=False, onerror=onError)
time.sleep(0.5)
os.remove(filepath)
return path + ".tar"
运行时出现此错误:
Traceback (most recent call last):
File "File.py", line 195, in <module>
main()
File "File.py", line 184, in main
dld = download()
File "File.py", line 132, in download
filename = decompress(os.path.join(start_dir, "Downloads", devname, filename
))
File "File.py", line 103, in decompress
shutil.rmtree(path, ignore_errors=False, onerror=onError)
File "C:\Program Files (x86)\python27\lib\shutil.py", line 247, in rmtree
rmtree(fullname, ignore_errors, onerror)
File "C:\Program Files (x86)\python27\lib\shutil.py", line 247, in rmtree
rmtree(fullname, ignore_errors, onerror)
File "C:\Program Files (x86)\python27\lib\shutil.py", line 256, in rmtree
onerror(os.rmdir, path, sys.exc_info())
File "C:\Program Files (x86)\python27\lib\shutil.py", line 254, in rmtree
os.rmdir(path)
WindowsError: [Error 145] The directory is not empty: 'C:\\Users\\Vaibhav\\Deskt
op\\Folder\\Downloads\\toro\\_toro_nightly_test\\system\\app'
这是我从https://stackoverflow.com/a/2656405/2518263获得的 onError :
def onError(func, path, exc_info):
"""
Error handler for ``shutil.rmtree``.
If the error is due to an access error (read only file)
it attempts to add write permission and then retries.
If the error is for another reason it re-raises the error.
Usage : ``shutil.rmtree(path, onerror=onerror)``
"""
if not os.access(path, os.W_OK):
# Is the error an access error ?
os.chmod(path, stat.S_IWUSR)
func(path)
else:
raise
我只在随机场合得到错误。解压缩功能在 75% 的时间内工作。
我不知道为什么我会收到这个错误。有人可以提出更好的方法或解决此错误的方法。
我刚换了:
shutil.rmtree(path, ignore_errors=False, onerror=onError)
和:
for root, dirs, files in os.walk(path, topdown=False):
for name in files:
filename = os.path.join(root, name)
os.chmod(filename, stat.S_IWUSR)
os.remove(filename)
for name in dirs:
os.rmdir(os.path.join(root, name))
time.sleep(0.5)
os.rmdir(path)
现在它就像一个魅力。
编辑:没关系!我仍然会收到错误,但很少见,现在大约有 20% 的时间!请帮忙!
编辑2:
好的,所以如果我提取到一个临时文件,我不会得到错误,所以我使用这个代码:
import tempfile
def decompress(filepath):
with zipfile.ZipFile(filepath) as zip:
tmp = tempfile.mkdtemp(dir=os.getcwd())
zip.extractall(tmp)
with tarfile.open(filepath[:-4] + ".tar", 'w') as tar:
for object in os.listdir(tmp):
tar.add(os.path.join(tmp, object), arcname=object)
time.sleep(1)
shutil.rmtree(tmp)
os.remove(filepath)
return filepath[:-4] + ".tar"
我现在工作!(希望错误不会再次发生)
编辑 3:我再次收到错误!!!!!!!!!!这真的让我很紧张。请帮助某人。
