Question

我试图在Windows 8.1和python 2.7.9上使用zipfile库。

我只想在zipfile.open（）之后删除library.zip，但os.remove（）抛出＆＃34; WindowsError [错误32]＆＃34;并且看起来zipfile没有用块释放zip文件。

WindowsError 32表示＆＃34;进程无法访问该文件，因为它正被另一个进程使用。＆＃34;

那么，如何删除这个library.zip文件？

代码：

import os
import zipfile as z

dirs = os.listdir('build/')
bSystemStr = dirs[0]

print("[-] Merging library.zip...")
with z.ZipFile('build/' + bSystemStr + '/library.zip', 'a') as z1:
    with z.ZipFile('build_temp/' + bSystemStr + '/library.zip', 'r') as z2:
        for t in ((n, z2.open(n)) for n in z2.namelist()):
            try:
                z1.writestr(t[0], t[1].read())
            except:
                pass

print("[-] Cleaning temporary files...")
os.remove('build_temp/' + bSystemStr + '/library.zip')

错误：

我认为您必须在删除存档之前关闭存档，或者如python文档中所述那样退出程序https://docs.python.org/2/library/zipfile.html#zipfile.ZipFile.close

在删除档案之前运行z1.close()和z2.close()

您的代码必须如下所示：

import os
import zipfile as z

dirs = os.listdir('build/')
bSystemStr = dirs[0]

print("[-] Merging library.zip...")
with z.ZipFile('build/' + bSystemStr + '/library.zip', 'a') as z1:
    with z.ZipFile('build_temp/' + bSystemStr + '/library.zip', 'r') as z2:
        for t in ((n, z2.open(n)) for n in z2.namelist()):
            try:
                z1.writestr(t[0], t[1].read())
            except:
                pass

         z2.close()

     z1.close()


print("[-] Cleaning temporary files...")
os.remove('build_temp/' + bSystemStr + '/library.zip')

如果我错了，请纠正我。

Python zipfile不会发布zip文件
