python3 setup.py define JEP_NUMPY_ENABLED=1 but build via pip3 defines it disabled JEP_NUMPY_ENABLED=0

[maveric2]

If I build jep with python3 setup.py the jep NumPy support gets enabled (-DJEP_NUMPY_ENABLED=1).
If I build it via pip3 jep-4.2.1.tar.gz the compile defines is not enabled (-DJEP_NUMPY_ENABLED=0).

How to enable NumPy support using pip?

Try using the --no-cache-dir option with pip.

unfortunately this has no effect, still -DJEP_NUMPY_ENABLED=0

pip seems to be building jep in an environment where numpy is not available. Try using the --no-build-isolation option should build it in your normal python environment where numpy is available.

pip3 -v install --no-build-isolation --no-binary :all: .

unfortunately not ;-(

I think you need to pip install wheel before installing jep. When pip sets up the build isolation I think it includes wheel in the environment for you but without the isolation you have to manually install wheel. Unfortunately I can't find anyway to just skip the wheel step and install directly with pip.
