Question

我正在研究AI Sweigart的“使用python自动化无聊的东西”项目9.5。

程序将当前文件夹备份到ZIP文件中。

我已经完成了编码，当我通过Terminator运行.py文件时，它可以正常工作。

这是我的代码：

#!/usr/bin/env python3
# backupToZip.py - backup whole folder into a ZIP file whose name increments

import zipfile, os

def backupToZip(folder):
    folder = os.path.abspath(folder) #make sure it's abspath

    # Figure out filename
    number = 1
    while True:
        zipFilename = os.path.basename(folder) + '_' + str(number) + '.zip'
        if not os.path.exists(zipFilename):
            break
        number = number + 1

    # create the ZIP file
    print('Creating %s...' % (zipFilename))
    backupZip = zipfile.ZipFile(zipFilename, 'w')

    # walk the entire folder tree and compress the files in each folder.
    for foldername, subfolders, filenames in os.walk(folder):
        print('Adding files in %s...' % (foldername))
        # add the current folder to the ZIP file
        backupZip.write(foldername)
        for filename in filenames:
            newBase = os.path.basename(folder) + '_'
            if filename.startswith(newBase) and filename.endswith('.zip'):
                continue # don't backup the backup ZIP files
            backupZip.write(os.path.join(foldername, filename))
    backupZip.close()
    print('Done')

backupToZip('.')

然后，我想使其更易于使用-通过双击文件来运行该文件。

然后我将文件名从backupToZip.py更改为backupToZip.py.command。在Terminator中使用“ chmod + x backupToZip.py.command”授权文件。

然后我尝试双击该文件，但弹出错误：

我意识到也许程序无法识别带有'。'的当前文件夹路径。然后，我将代码的最后一行更改为：

backupToZip('.')

收件人：

folder = os.getcwd()
backupToZip(folder)

再次弹出权限错误：

我如何找出问题出在哪里？

我想压缩当前文件夹时出现PermissionError
