pip install . fails, while
python3 ./setup.py install succeeds.
I am trying to compile and install a module that is purely local for now, written in C++. The name of the module is tcore. The module uses python C API and numpy C API.
pip install complains it cannot find numpy which is imported by my setup.py, however the import is actually correct and the setup.py import is very trivial.
numpy is correctly installed and can be imported:
pierre@pierre-maxm3 tcore % pip install numpy
Requirement already satisfied: numpy in /Library/Frameworks/Python.framework/Versions/3.12/lib/python3.12/site-packages (1.26.2)
pierre@pierre-maxm3 tcore % python3
Python 3.12.3 (v3.12.3:f6650f9ad7, Apr 9 2024, 08:18:47) [Clang 13.0.0 (clang-1300.0.29.30)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
>>> numpy_path = numpy.get_include()
>>> print(numpy_path)
/Library/Frameworks/Python.framework/Versions/3.12/lib/python3.12/site-packages/numpy/core/include
Of course python3 setup.py install works and install my module properly.
But pip install fails to load numpy. It looks into /var/private/folders directory that doesn't exist... this is pip 24.3.1. Any idea? What is the problem with pip?
pierre@pierre-maxm3 tcore % pip install .
DEPRECATION: Loading egg at /Library/Frameworks/Python.framework/Versions/3.12/lib/python3.12/site-packages/tcore-1.0.0-py3.12-macosx-10.9-universal2.egg is deprecated. pip 25.1 will enforce this behaviour change. A possible replacement is to use pip for package installation. Discussion can be found at https://github.com/pypa/pip/issues/12330

Modern pip uses build isolation, it uses a transient virtual env to build a wheel and then installs the wheel into the target environment; this transient virtual env is your absent temporary directory; pip removes it after success or failure so you cannot find it. There are two ways to work around the problem:
numpy into the current environment and install the source code without build isolation:pip install numpy
pip install --no-build-isolation .
pyproject.toml and declare numpy as a build-time dependency:[build-system]
build-backend = "setuptools.build_meta"
requires = ["setuptools", "numpy==1.26.2"]
