error: from pydrive2.auth import GoogleAuth

[abubelinha]

I have a script that I use once a year or so. Usually the only problem I have is needing to regenerate my credentials .txt file if it has expired.

But today I hit an error I had not seen before. It seems to be related to the OAuth made easy 1st step:

I use Windows 7, Python 3.8.7, and my PyDrive2 version is the last release 1.16.0. Any hints? Should I upgrade some other libraries?

Thanks a lot in advance @abubelinha

@abubelinha from just a brief google https://stackoverflow.com/questions/73830524/attributeerror-module-lib-has-no-attribute-x509-v-flag-cb-issuer-check ?

Thanks @shcheklein , I had already seen that but I don't understand it.
I had not changed pip or any other things since the last time I used my PyDrive2 script. Have you also had to upgrade pip or pyopenssl at some point during the last year to keep using PyDrive2?

Not that I'm aware of tbh.

Could you please check your pyopenssl version? Mine seems to be 20.0.1

pip show pyopenssl
Name: pyOpenSSL
Version: 20.0.1
Summary: Python wrapper module around the OpenSSL library
Home-page: https://pyopenssl.org/
Author: The pyOpenSSL developers
Author-email: cryptography-dev@python.org

Location: c:\users\abu\appdata\local\programs\python\python38\lib\site-packages
Requires: cryptography, six
Required-by: PyDrive2

Nevermind. Thanks @shcheklein The problem solved with:

pip install --upgrade pyopenssl

and now:

pip show pyopenssl
Name: pyOpenSSL
Version: 23.2.0
Summary: Python wrapper module around the OpenSSL library
Home-page: https://pyopenssl.org/

What I don't understand is:
Shouldn't pyopenssl have already been upgraded to the required version when I upgraded pydrive2 just a few minutes before?

[shcheklein]

PyDrive specifies it as pyOpenSSL >= 19.1.0 . I'm not sure if there is a need to bump the requirement, since I don't know what was the underlying issue. Was there some critical error in the previous version that got fixed?

[abubelinha]

No idea. I just know what I mentioned above. All this is pretty obscure to me.

It seems pyopenssl was installed in my system when I first installed PyDrive (or PyDrive2), since no other packages required it. But at some point (today) PyDrive2 failed to work properly despite my pyopenssl was 20.0.1 > 19.1.0, as I described Did you check your installed version?

EDIT: Anyway, my PyDrive2 script works again after the pyopenssl upgrade, so it is not an issue for me anymore. Don't know if all this means requirements should be changed or not. Feel free to close the issue when you decide.
