Error installing scipy-1.2.3

[Caleb Springer]

I am trying to install Sage from source code on a new 2020 MacBook Air with macOS 10.15.6.

Unfortunately, scipy-1.2.3 failed to install.  I am posting this here with the log file attached because the installer directed me to do so. 

Incidentally, I can actually still call Sage from the terminal, and basic commands work correctly. (I am actually too ignorant to know what parts of Sage are broken by scipy-1.2.3 being absent.)

https://trac.sagemath.org/ticket/30067 has a workaround.

Hi~

 I'm also trying to install from the source code, and I'm receiving an error that spicy-1.2.3 failed to build. I've looked at the ticket you posted, but I'm not sure if I'm interpreting it properly:

I executed brew install gcc@9 at the command line before running make again, but I'm still getting an error. Do I need to uninstall something first?

Thanks, my error log is attached.

If you rerun ./configure with

FC=gfortran-9 ./configure

Then it should use gfortran-9 as your Fortran compiler when making sage.

[Dima Pasechnik]

if you have a recent Sage beta you should not need gfortran-9, it would also work with the default, gfortran, from gcc package, 

IIRC.

Yes, this worked. Thank you!
