Deploying Django App Using Google Cloud Run - gcloud builds submit error - django

Question

I've followed the tutorial for deploying Django on Cloud Run (https://codelabs.developers.google.com/codelabs/cloud-run-django), and I followed the exact instructions up to "Build your application image" on Step 7: "Configure, build and run migration steps".
When running the command:
gcloud builds submit --pack image=gcr.io/${PROJECT_ID}/myimage
[builder] × python setup.py egg_info did not run successfully.
[builder] │ exit code: 1

[builder] Error: pg_config executable not found.
[builder]
[builder] pg_config is required to build psycopg2 from source. Please add the directory
[builder] containing pg_config to the $PATH or specify the full executable path with the
[builder] option:
[builder]
[builder] python setup.py build_ext --pg-config /path/to/pg_config build ...
[builder]
[builder] or with the pg_config option in 'setup.cfg'.
[builder]
[builder] If you prefer to avoid building psycopg2 from source, please install the PyPI
[builder] 'psycopg2-binary' package instead.
[builder]
[builder] For further information please check the 'doc/src/install.rst' file (also at
[builder] <https://www.psycopg.org/docs/install.html>).

[builder] note: This error originates from a subprocess, and is likely not a problem with pip.

This is preventing me from continuing to the next step, and I'm not sure how to troubleshoot this issue.
I've tried pip installing psycopg2-binary as the error suggests, however it made not difference and because it's Google Cloud I wouldn't want to mess around with too many unorthodox installs, perhaps there's something I'm missing here? I've searched everywhere, and I haven't run into this exact issue.
