python not found

Hello! I'm trying my hand at nixpacks.toml for the first time. During the install step, it tells me:

 => ERROR [stage-0  6/14] RUN --mount=type=cache,id=kfWxs0zicKI-/root/cache/pip,target=/root/.cache/pip python -m venv --copies /opt/venv && . /opt  0.1s

I don't know much about nixpacks, but I'm assuming this is because I'm running on my Mac, which uses python3 and pip3 by default? This is coming from the tool-supplied install step:

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

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

try this -

providers = ["python"]

[phases.setup]
    nixPkgs = ["...", "ollama", "geoipupdate"]

[phases.setup-ollama]
    dependsOn = ["setup"]
    cmds = ["ollama serve", "ollama run llama3.1"]

[phases.setup-geoipupdate]
    dependsOn = ["setup"]
    cmds = ["build-geoip-conf.sh", "geoipupdate -f ./GeoIP.conf -d ./maxmind-dbs"]

[start]
    cmd = "python3 ./webapp/main.py"

providers = ["python"]

[phases.setup]
    nixPkgs = ["...", "ollama", "geoipupdate"]

[phases.setup-ollama]
    dependsOn = ["setup"]
    cmds = ["ollama serve", "ollama run llama3.1"]

[phases.setup-geoipupdate]
    dependsOn = ["setup"]
    cmds = ["build-geoip-conf.sh", "geoipupdate -f ./GeoIP.conf -d ./maxmind-dbs"]
