Meson and distutils ways of doing things#
Old workflows (numpy.distutils based):
The runtests.py file was removed in commit 0f73f92255253ec5dff2de5ca45d8d3bdda03f92 [^1^_].
- python runtests.py
- python setup.py build_ext -i+- export PYTHONPATH=/home/username/path/to/scipy/reporoot(and then edit pure Python code in SciPy and run it with- python some_script.py).
- python setup.py develop- this is similar to (2), except in-place build is made permanently visible in env.
- python setup.py bdist_wheel+- pip install dist/scipy*.whl- build wheel in current env (i.e. uses installed numpy, etc.) and install it.
- pip install .- build wheel in an isolated build env against deps in- pyproject.tomland install it. Note: be careful, this is usually not the correct command for development installs - typically you want to use (4) or- pip install . -v --no-build-isolation.
New workflows (Meson and meson-python based):
- python dev.py
- pip install -e . --no-build-isolation(see the- meson-pythondocs)
- the same as (2) 
- python -m build --no-isolation+- pip install dist/scipy*.whl- see pypa/build.
- pip install .
