python - 在 Python 错误中解压缩 rar 文件

Question

我正在尝试使用 pyunpack 解压缩文件，但我总是遇到错误。如果我使用 zip 文件，一切正常，但使用 rar 文件则不行。这是我的代码:

from pyunpack import Archive
Archive('C:/Users/Username/Desktop/teste/Desktop2.rar').extractall('C:/Users/Username/Desktop/teste')

这是我得到的错误:

Traceback (most recent call last):
  File "c:\Python34\lib\site-packages\easyprocess\__init__.py", line 255, in start
    cwd=self.cwd,
  File "c:\Python34\lib\subprocess.py", line 859, in __init__
    restore_signals, start_new_session)
  File "c:\Python34\lib\subprocess.py", line 1112, in _execute_child
    startupinfo)
FileNotFoundError: [WinError 2] The system couldn't find the specified file

During handling of the above exception, another exception occurred:

您知道可能是什么问题吗？

Answer 1

问题可能是您的路径中没有解压缩工具，这意味着它不能从命令行调用(这正是 patool 所做的)。只需将您的 7-zip(或您正在使用的任何其他内容)文件夹放入路径即可。
