build error running python activating venv and installing requirements.txt

Question

Trying to fix this error. Thanks for any pointers.

Here's the command: "python -m venv --copies /opt/venv && . /opt/venv/bin/activate && pip install -r requirements.txt" did not complete successfully: exit code: 127

And error code: /bin/bash: line 1: python: command not found

This probably means that python is not installed or not in your path.

Depending on your image maybe python is installed as python3 so you may try with

`python3 -m venv --copies /opt/venv && . /opt/venv/bin/activate && pip install -r requirements.txt or install python-is-python3`

Try to find out with which python and If python is installed just add it to your path `export PATH="/path/to/python/bin:$PATH"`

I would also recommend better using UV to run python within containers, is super easy and cool.

`FROM python:3.12-slim-bookworm `

`COPY --from=ghcr.io/astral-sh/uv:latest /uv /uvx /bin/`

Then `uv run python -m` etc.
