Im sure anyone reading this is all too familiar with issues such as mine (given by the number of posts referring to this issue). I am running Mac OS X Big Sur (11.3.1). I have python 3.9.4 installed via pyenv which is installed through home-brew. I have also installed FFTW through home-brew and followed the Mac installation instructions.
Unfortunately pyfftw still fails to find the FFTW libraries when installing via pip. Any advice would be greatly appreciated.
