我正在尝试使用 pyunpack 解压缩文件，但总是出错。如果我使用 zip 文件，一切正常，但 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__

    startupinfo)
FileNotFoundError: [WinError 2] The system couldn't find the specified file

During handling of the above exception, another exception occurred:

您对可能出现的问题有任何想法吗？

问题可能是您的路径中没有您的 unraring 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（或您正在使用的其他任何东西）文件夹放到路径中，就可以了。

跑步sudo apt install unrar为我解决了这个问题。
