Unable to install scipy on macOS Big Sur (Intel hardware)

See original GitHub issue

After Big Sur update I’m not able to install scipy in any of my virtualenvs.

pip install scipy

generate this error

Wow, this worked. Thank you:

Install openblas:

$ brew install openblas

I used pip3 to install scipy

$ SYSTEM_VERSION_COMPAT=1 \
LDFLAGS="-L/usr/local/opt/openblas/lib" \
CPPFLAGS="-I/usr/local/opt/openblas/include" \
OPENBLAS="$(brew --prefix openblas)" \
pip3 install scipy

Success!!!

For anyone else that needs SciPy to just install for now, here’s what I did to make it work:

Find your tag

$ pip install packaging
$ python -c"from packaging import tags; print('\n'.join([str(t) for t in tags.sys_tags()]))" |head -5

cp38-cp38-macosx_11_0_x86_64

Download 10_9 wheel from Pypi https://pypi.org/project/scipy/#files
Rename downloaded file to match your tag $ mv scipy-1.5.4-cp38-cp38-macosx_10_9_x86_64.whl scipy-1.5.4-cp38-cp38-macosx_11_0_x86_64.whl
Install wheel $ pip install scipy-1.5.4-cp38-cp38-macosx_11_0_x86_64.whl
