Describe the bug

I'm using CodeCommit for CI/CD to an AWS Amplify application.

During the amplifyPush, this error would occur on previously working functions with no changes:

2023-06-27T09:27:41.100Z [INFO]: Installing dependencies from Pipfile.lock (2a8f7d)...

Reproduction steps

Build any previously working AWS Amplify application with a Python lambda function in the backend.

Build Settings

phases:
    build:
      commands:
        - update-alternatives --install /usr/bin/python3 python3 /usr/local/bin/python3.9 15
        - /usr/local/bin/python3.9 -m pip install --upgrade pip
        - /usr/local/bin/pip3.9 install --upgrade setuptools
        - /usr/local/bin/pip3.9 install pipenv
        - amplifyPush --simple

### Log output

### Additional information

The solution ended up being easy.  Change a single line in the setup.py of every function.

from distutils.core import setup

from setuptools import setup

setup(name='src', version='1.0')

After that, builds are successful.

Hi @breencp 👋 , thanks for reaching out to us and for sharing the detailed insights on your Amplify environment.

While reviewing your backend build logs, I came across this particular error error: invalid command 'egg_info' which seems related to a breaking change with the latest pipenv release: pypa/pipenv#5753

Thank you for sharing the workaround which helped unblock your backend builds and this is going to be very useful for other developers in the community who run into something similar with their backend lambda functions.

We really appreciate it! 👏

Hello Team,

Faced the same error when building backend with python functions. Pinning pipenv version to previous version helped me to move past the issue.

version: 1
backend:
  phases:
    build:
      commands:
        - '# Execute Amplify CLI with the helper script'
        - update-alternatives --install /usr/bin/python3 python3 /usr/local/bin/python3.9 12
        - /usr/local/bin/pip3.9 install --user pipenv==2023.6.18
        - python3 --version
        - amplifyPush --simple
