'pip3 install patool' 后无法使用 patoolib

Question

I am using a macbook, and have python3 installed and using spyder .

I have installed patool and it's listed in pip3 list .

When I import patoolib and run the program it says, ModuleNotFoundError: No module named 'patoolib'

So I am not able to run the extract related programs.

import patoolib
import os
import glob

def extract_files(inputdir = '/Users/satishvadlamudi/Python_spyder_projects/zipped',outputdir = '/Users/satishvadlamudi/Python_spyder_projects/extracted'):
    os.chdir(inputdir)
    archives = glob.glob('*.gz')
    #print(archives)
    if not os.path.exists(outputdir):
        os.mkdirs(outputdir)
    files = os.listdir('/Users/satishvadlamudi/Python_spyder_projects/extracted')
    print (files)
    for archive in archives:
        if archive[:-3] not in files:
            patoolib.extract_archive(archive, outdir = outputdir)

Answer 1

Note that "pip" is also a python module. If you see pip3 list give you the module installed but python3 complaint about ModuleNotFoundError, you may want to check if pip3 and python3 mean the same thing.

Try with python3 -m pip list -v , which the -v tells you the installed location as well. If you see the module there, then the same python3 interpretor should be able to find the module. If not, you may want to consider setting up PYTHONPATH env variable.

In order to import :

import patoolib

you need to install patool first:

pip install patool
