I probably wasn't clear on this, but I was addressing different points, the "old" kwant py2 installation, can't be updated.
I see.
A Mac related thing; if you installed python with brew, it's recommended that you install everything without sudo rights.
Right, but since there was a permission denied, it appears that you cannot remove the file. You can double-check the permissions or even manually remove the offending file. Anton

Hi Bas,
I don't have a mac, but it appears that you executed the first command without the superuser permissions. It also tries to modify the python 2.7 installation instead of 3.4, so you're definitely not doing what you want. Probably replacing pip with pip3 or python with python3 would help (if it's pip that you're using).
As far as the second command goes, did you try following the suggestion and using the fortran flags option?
Best, Anton

Hi all,
Upon experimenting with Joe’s python3 version of kwant on OS X I found that mumps has a well maintained homebrew formula of its own in the homebrew/science tap: https://github.com/Homebrew/homebrew-science/blob/master/mumps.rb
I think it might be useful to simplify the kwant installation on OS X.
Also the tinyarray and kwant version are outdated on https://github.com/michaelwimmer/homebrew-kwant
Updating tinyarray via pip doesn’t work:

Changing the kwant tarball to the 1.0.4 file on the brew formula also doesn’t work (https://github.com/basnijholt/homebrew-kwant/blob/master/kwant.rb):
