Since that python interpreter apparently exists, the problem is likely 
with the "interpreter" for it. Are these programs perhaps for a foreign 
architecture (e.g. for 32-bit on a 64-bit system)?

Try running the "file" command on the python interpreter mentioned in 
that error. Running that on the python interpreter on my system shows:

  /usr/bin/python2.7: ELF 64-bit LSB pie executable x86-64, version 1 
  (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, 
  for GNU/Linux 3.2.0, 
  BuildID[sha1]=e56ca1ed2d9b9d858a1cdea846025376b26aa6f9, stripped

Try to verify that the interpreter shown there (in the above case that's 
/lib64/ld-linux-x86-64.so.2) exists. You should even be able to run that 
directly and get a usage message.
