spack is central to xsdk project - which supports petsc.
Design mistakes are fine, but they should be corrected. Matt

Why are we supporting this? Spack seems to generate a string of maint requests while providing marginal value at best.

petsc@develop worked with python-3.7.2, Satish. Thank you. The "No module named site" error did not have 'python2' in the PATH, only 'python3'.
Elizabeth, approach #2 got me very close, but there were a few minor issues in that commit (for instance, the use of a deprecated string.replace in config/PETsc/Configure.py).

Petsc4py should work fine with Python-3 (has for quite a while). The next PETSc release is due next month, give or take. You can use petsc@master in the mean time.
This is petsc@develop - in spack notation. This is fixed to work with python3.
[and petsc4py@develop should now default to using petsc@develop]

I am using the latest development version of spack (commit f65a115).
The spack recipe for petsc builds fine with python-2.7-x.
When I modify the petsc package to build using python-3.x, I get "ImportError: No module named site."
I changed only one line in the petsc package to:
depends_on('[email protected]:', type='build', when='@:3.10.99')
This is a strange error. It should work [with petsc-3.10.x] if you have 'python2' in PATH.
