# 🐍 Virtualenv bootstrap & setup
|
|
#
|
|
# This script is responsible for creating the Python virtualenv
|
|
# used by the entire Infinito.Nexus toolchain.
|
|
#
|
|
# Important design rule:
|
|
# ❗ The venv Python interpreter CANNOT be used before the venv exists.
|
|
# ❗ Therefore we must bootstrap using system python3 first.
|
|
#
|
|
# Lifecycle:
|
|
# 1) Use system python3 to create the venv
|
|
# 2) Afterwards, Makefile provides PYTHON=${VENV}/bin/python
|
|
# 3) All tooling runs inside the venv from then on
|
|
#
|
|
# This avoids chicken-and-egg failures in CI and on fresh machines.
|
