I am encountering a strange new issue with building my python 3.7 standard
app when I modify the requirements.txt (if I don't modify it, I suppose
it's using the cached deps). The issue started perhaps a few weeks ago.
In the build log (on the cloud build page, for the build triggered by
'gcloud app deploy app.yaml cron.yaml`, in the 'builder' step) I get the
following failure:
INFO pip_install_from_wheels took 0 seconds

Note, I DO NOT have pip specified in my requirements.txt. If I freeze with
--all (which includes my version of pip, 20.1.1), it also does not work.
However, If I downgrade pip in my virtualenv to 19.2.3 (the version from
the error) AND freeze with --all, the build succeeds.
Furthermore, at the top of the build log, I get the following deprecation
notice, presumably from
https://github.com/GoogleCloudPlatform/cloud-builders
Pulling image: gcr.io/gae-runtimes/python37_app_builder:
python37_20200601_3_7_7_RC00
***** NOTICE *****
Alternative official `docker` images, including multiple versions across
multiple platforms, are maintained by the Docker Team. For details, please
visit https://hub.docker.com/_/docker.
However, because I am using the standard python 3.7 environment, as far as
I know there is no configuration setting for me to change to docker image
used for build/deployment.
Searching, I found the following links with others having similar errors,
but I found no official statement from the app engine team:
- https://safecontrols.blog/2019/01/ (says google fixed june 1st)
- https://github.com/GoogleCloudPlatform/cloud-builders/issues/485 (closed
WONTFIX and locked May 16)
- https://issuetracker.google.com/issues/131663964 (this says the issue is
fixed June 17th)
- https://issuetracker.google.com/issues/159736137 (marked dupe of previous)
Am I doing something wrong? What is the long term solution to selecting pip
versions? Is there an official statement I've missed?
Also, how can I fix the deprecation warning on the builder? As far as I
know I am not manually selecting anything deprecated.
Thanks,
Allan Wirth
