Cryptography cant find file. #960

Open mdevore300 opened 11 months ago

mdevore300 commented 11 months ago

Describe the bug

It can't find a file in the cryptography program. Import Cryptography on its own works fine.

Have you tried repairing the PDF?

No as I can't even import pdfplumber

Code to reproduce the problem

So, i've updated all dependencies finally. Still getting the same error. So all i was trying to do was in spyder, import pdfplumber so i could run a script. So I highlighted import pdfplumber, then hit F9 The full traceback is as follows:

File "", line 1, in import pdfplumber

File "C:\ProgramData\Anaconda3\lib\site-packages\pdfplumberinit.py", line 14, in for .pdf import PDF

Hi mdevore300

If you look at the traceback, the error is coming from pdfminer trying to load cryptography (pdfplumber uses pdfminer).

Import Cryptography on its own works fine.

Not too familiar with spyder or anaconda but the first step I'd try would be to run the actual offending line in isolation inside a minimal environment (which appears to be an "Anaconda Prompt" session?) to try figure out where the problem is.

from cryptography.hazmat.bindings._rust import exceptions as rust_exceptions
mdevore300 commented 11 months ago

Okay, I will have to try it on Tuesday and see if there is still an error.

mdevore300 commented 11 months ago

so i tried from cryptography.hazmat.bindings._rust import exceptions as rust_exceptions it as a standalone and it gave the same error.

cannot import name 'exceptions' from 'cryptography.hazmat.bindings._rust' (unknown location).

Yes, that suggests your cryptography installation is somehow "broken".

Not used anaconda, but it looks like the next step in debugging would be creating a fresh environment and seeing if the issue persists.

https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html#creating-an-environment-with-commands

# 4. To create an environment with a specific package:

conda create -n myenv cryptography

You can try conda install cryptography -c conda-forge
