Environment details

• OS type and version: macOS 15.7.1 chip M3
• Python version: 3.13.9
• pip version: 25.3
• google-auth-oauthlib version: 1.2.3

Steps to reproduce

1. Install requirements.txt with specific dependencies.

Code example

# requirements.txt

google-api-core==2.28.1 ; python_version >= "3.13" and python_version < "4.0"
google-auth-oauthlib==1.2.3 ; python_version >= "3.13" and python_version < "4.0"
google-auth==2.45.0 ; python_version >= "3.13" and python_version < "4.0"

Stack trace

INFO: pip is looking at multiple versions of google-auth-oauthlib to determine which version is compatible with other requirements. This could take a while.
ERROR: Cannot install -r ./packages/run_evaluation/requirements.txt (line 18), -r ./packages/run_evaluation/requirements.txt (line 19) and google-auth==2.45.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested google-auth==2.45.0
    google-api-core 2.28.1 depends on google-auth<3.0.0 and >=2.14.1
    google-auth-oauthlib 1.2.3 depends on google-auth<2.42.0 and >=2.15.0

Not sure if this is intended so I'm asking here to know better hoe to approach this dependencies. The previous version google-auth-oauthlib==1.2.2 works with that version.

Thanks!
