I created a virtualenv with pypy and tried to install scipy, but installation ended with the following error:

distutils.errors.DistutilsError: Setup script exited with error: Command "cc -O2 -fPIC -Wimplicit -O2 -fPIC -Wimplicit -O2 -fPIC -Wimplicit -DHAVE_NPY_CONFIG_H=1 -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE=1 -D_LARGEFILE64_SOURCE=1 -DNO_ATLAS_INFO=1 -DHAVE_CBLAS -Ibuild/src.linux-x86_64-3.2/numpy/core/src/private -Inumpy/core/include -Ibuild/src.linux-x86_64-3.2/numpy/core/include/numpy -Inumpy/core/src/private -Inumpy/core/src -Inumpy/core -Inumpy/core/src/npymath -Inumpy/core/src/multiarray -Inumpy/core/src/umath -Inumpy/core/src/npysort -I/home/luke/Programowanie/Python/connect4/venv-pypy/include -Ibuild/src.linux-x86_64-3.2/numpy/core/src/private -Ibuild/src.linux-x86_64-3.2/numpy/core/src/private -Ibuild/src.linux-x86_64-3.2/numpy/core/src/private -c numpy/core/src/multiarray/scalarapi.c -o build/temp.linux-x86_64-3.2/numpy/core/src/multiarray/scalarapi.o" failed with exit status 1

There is a specific numpy version suited for pypy, but the only thing I found about scipy is an old call for donations. Has anything changed since then?

Yes, it is possible, starting from Scipy 1.1.0. New enough PyPy (>= 6.0.0) and Numpy are however required, numpy>= 1.14.3, and preferably numpy>=1.15.0 when it's released. Installation can be done via the usual

pypy3 -mpip install numpy
pypy3 -mpip install scipy

assuming you have BLAS/LAPACK installed, so first you should make sure you are able to install numpy/scipy on normal Python from sources.

Nobody probably has tried whether this works with Pypy on Windows, so you are on your own there. It also probably won't work with NumPyPy --- you need the vanilla Numpy.

The other answers say "No" since that was the situation before May 2018.
