How to use pyunpack to unpack .7z file?
Question:
Im trying to unpack a 7z file but got an error.
This is the code:
from pyunpack import Archive
Archive('E:/Desktop/vnpt2/2_1_0_2841.7z').extractall('E:/Desktop/vnpt2/new')
And this is error:
Traceback (most recent call last):
File "E:Desktopvnpt2zip.py", line 2, in <module>
Archive('E:/Desktop/vnpt2/2_1_0_2841.7z').extractall('E:/Desktop/vnpt2/new')
File "C:Python27libsite-packagespyunpack__init__.py", line 90, in extractall
self.extractall_patool(directory, patool_path)
File "C:Python27libsite-packagespyunpack__init__.py", line 62, in extractall_patool
raise PatoolError('patool can not unpackn' + str(p.stderr))
pyunpack.PatoolError: patool can not unpack
patool error: error extracting E:Desktopvnpt22_1_0_2841.7z: could not find an executable program to extract format 7z; candidates are (7z,7za,7zr),
How can I fix it?
Answers:
You can instead use the combination of py7zr
package and shutil
package to unzip 7z file.
Steps
-
Pip install py7zr
-
Run the below code:
from py7zr import unpack_7zarchive
import shutil
shutil.register_unpack_format('7zip', ['.7z'], unpack_7zarchive)
shutil.unpack_archive('filename.7z', '/unzip_path')
If you are using Mac OS, install 7zip with command
brew install p7zip
On windows download and install 7zip from https://www.7-zip.org/download.html
Then update the PATH variable to point the directory containing 7za.exe
