Question

我试图在解压缩Windows上的内容后删除压缩文件。内容可以存储在zip中的文件夹结构中。我使用with语句并认为这会关闭类似文件的对象（source var）和zip文件。我删除了与保存源文件相关的代码行。

import zipfile
import os

zipped_file = r'D:\test.zip'

with zipfile.ZipFile(zipped_file) as zip_file:
    for member in zip_file.namelist():
        filename = os.path.basename(member)
        if not filename:
            continue
        source = zip_file.open(member)

os.remove(zipped_file)

返回的错误是：

WindowsError: [Error 32] The process cannot access the file because it is being used by another process: 'D:\\test.zip'

我试过了：

循环os.remove行，以防出现轻微的时间问题
明确使用close而不是with statment
尝试使用本地C驱动器并映射D驱动器

不是将字符串传递给ZipFile构造函数，而是可以传递一个像object这样的文件：

import zipfile
import os

zipped_file = r'D:\test.zip'

with open(zipped_file, mode="r") as file:
    zip_file = zipfile.ZipFile(file)
    for member in zip_file.namelist():
        filename = os.path.basename(member)
        if not filename:
            continue
        source = zip_file.open(member)

os.remove(zipped_file)

Answer 2

您正在打开zip中的文件...这会在整个zip文件上创建文件锁。关闭内部文件首先打开...通过循环结束时的source.close（）

import zipfile
import os

zipped_file = r'D:\test.zip'

with zipfile.ZipFile(zipped_file) as zip_file:
    for member in zip_file.namelist():
        filename = os.path.basename(member)
        if not filename:
            continue
        source = zip_file.open(member)
    source.close()

os.remove(zipped_file)

Answer 3

您也可以这样做，效果很好：

import os, shutil, zipfile

fpath= 'C:/Users/dest_folder'
path = os.getcwd()

for file in os.listdir(path):
    if file.endswith(".zip"):
        dirs = os.path.join(path, file)

if os.path.exists(fpath):
    shutil.rmtree(fpath)
_ = os.mkdir(fpath)

with open(dirs, 'rb') as fileobj:
    z = zipfile.ZipFile(fileobj)
    z.extractall(fpath)
    z.close()
os.remove(dirs)

Answer 4

在删除之前尝试close zipfile。
