I tried to read the python configuration code and it seems that the reason is self.framework is None and the reason for self.framework is None is in the script.py in my petsc-3.4.4/config/BuildSystem directory, the following code in function loadConfigure(self, argDB = None):

This problem has been reported before and it may happen occasionally.
Check the file $PETSC_DIR/$PETSC_ARCH/conf/RDict.db - see if it has a smaller size than usual. If this is the case, then the problem is that PETSc's configuration did not write this file completely, I don't know the reason.

Suggest to reconfigure PETSc.
