Python: ModuleNotFoundError: No module named '*'-CodePudding

I have a python script (parser.py) which imports crc32c like this:

import crc32c

// ... rest of the code

I have installed crc32c with the command:

arch -arm64  brew install crc32c

crc32c was installed here:

/opt/homebrew/Cellar/crc32c/1.1.1

When executing parser.py file like this:

python3.9 parser.py

Getting this error:

ModuleNotFoundError: No module named 'crc32c'

What is the way to show to the parser.py file, that crc32c is installed into particular directory?

I have tried doing like this:

sys.path.append('/opt/homebrew/Cellar/crc32c')

As well looked into similar question, but can not found solution for my problem.

CodePudding user response：

try

sys.path.append('/opt/homebrew/Cellar/')

or, if the package is inside /opt/homebrew/Cellar/crc32c/1.1.1 (this folder contains a package (=another folder) called crc32c)

sys.path.append('/opt/homebrew/Cellar/crc32/1.1.1/')

before importing the module.

you can try to debug this by calling help('modules') in your code after the sys.path.append has been called

CodePudding user response：

Unfortunately it looks like that isn't a python package:

There are python checksums available, for instance: https://pypi.org/project/crc32c/ python3.9 -m pip install crc32c and zlib.crc32()

That look like they may suit your needs
