Google app engine deployment fails- Error while finding module specification for 'pip' (At-CodePudding

We are using command prompt c:\gcloud app deploy app.yaml, but get the following error:

Running "python3 -m pip install --requirement requirements.txt --upgrade --upgrade-strategy only-if-needed --no-warn-script-location --no-warn-conflicts --force-reinstall --no-compile (PIP_CACHE_DIR=/layers/google.python.pip/pipcache PIP_DISABLE_PIP_VERSION_CHECK=1)"

Our Requirements.txt is as below. We are currently on Python 3.7 standard app engine

firebase_admin==3.0.0
sendgrid==6.9.3
google-auth==1.35.0
google-auth-httplib2==0.1.0
jinja2==3.0.3
MarkupSafe==2.0.1
pytz==2021.3
Flask==2.0.2
twilio==6.46.0
httplib2==0.20.2
requests==2.24.0
requests_toolbelt==0.9.1
google-cloud-tasks==2.7.1
google-cloud-logging==1.15.1
googleapis-common-protos==1.54.0

Please help.The above code was working well before updating the requirements.txt file. We tried to remove gunicorn to allow the system pickup the latest according to documentation here.

We have a subdirectory structure that stores all the .py files in controllers and db definitions in models. Our main.py has the following -

sys.path.append(os.path.join(os.path.dirname(__file__), '../controllers'))
sys.path.append(os.path.join(os.path.dirname(__file__), '../models'))

Does anyone know how to debug this error - Error while finding module specification for 'pip' (AttributeError: module '__main__' has no attribute '__file__'). What does this mean?

CodePudding user response：

The latest release of setuptools has been yanked by PyPi for which you're getting the above error.

Yanked files are always ignored, unless they are the only file that matches a version specifier that "pins" to an exact version using either == (without any modifiers that make it a range, such as .*) or ===. Matching this version specifier should otherwise be done as per PEP 440 for things like local versions, zero padding, etc.

Source: https://www.python.org/dev/peps/pep-0592/

What you can do as of now is pass the version of the package explicitly.

CodePudding user response：

Your setuptools version is likely to be yanked:

https://pypi.org/project/setuptools/60.3.0/

Not sure how to fix that without a working pip though.

CodePudding user response：

By installing the previous version 60.2.0 of setuptools before installing pip-tools helped me get it running.

pip install setuptools==60.2.0

CodePudding user response：

Setuptools 60.3.1 is out now. GitHub Link here.
