Installing using `pip` inside a virtual environment complains about `mpi4py` while it is installed #1296

Open kasra-keshavarz opened 11 months ago

kasra-keshavarz commented 11 months ago

Installing netCDF4 (GitHub version with commit f9dc8b2) inside a virtual environment using pip install causes an error complaining about the lack of mpi4py package. This error is thrown at the user regardless whether the mpi4py is installed within the same virtual environment or not. This is not limited to this version of netcdf4-python, as a few latest releases that I have tried, also demonstrate the same behaviour. Here is an example:

(test2) [netcdf4-python]$ pip install --no-binary mpi4py --no-cache mpi4py

You need to install with pip install --no-build-isolation

You may want to have a look at #1307.

It looks like creating an in-tree build backend could be a longterm solution instead of building without isolation.
