Docker way install not working

[jceintrey]

Hi, Thank you for your application. I've tried to use the docker file, and it seems there is something wrong.

Dockerfile:13

11 | WORKDIR "/scanner"
12 |
13 | >>> RUN pip install --no-cache-dir -r ./requirements.txt
14 |
15 | CMD ["python3", "Metascan.py"]

ERROR: failed to solve: process "/bin/sh -c pip install --no-cache-dir -r ./requirements.txt" did not complete successfully: exit code: 1

I've run into what I will assume is the same issue. I get the same error as above, but here is some additional output:

STEP 7/8: RUN pip install --no-cache-dir -r ./requirements.txt
error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
python3-xyz, where xyz is the package you are trying to
install.

If you wish to install a non-Kali-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
sure you have pypy3-venv installed.

If you wish to install a non-Kali-packaged Python application,
it may be easiest to use pipx install xyz, which will manage a
virtual environment for you. Make sure you have pipx installed.

For more information, refer to the following:
* https://www.kali.org/docs/general-use/python3-external-packages/
* /usr/share/doc/python3.13/README.venv

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.
Error: building at STEP "RUN pip install --no-cache-dir -r ./requirements.txt": while running runtime: exit status 1

For additional context, I'm using podman.
