Install bcrypt and it will work.

Try to run 'python' from another location (not where py-bcrypt was unpacked). 
I had same problem as you, when tried to run from ~/python-install/py-bcrypt-0.2
So I changed to ~ and tried again - everything worked fine :)

Python tries to import bcrypt from source folder 
(~/python-install/py-bcrypt-0.), it has folder bcrypt with __init__.py ...

Had to change "from _bcrypt import *" to "from _bcrypt import hashpw, 
encode_salt" for this module to work with pypy.

This works for me. Are you running python from a directory that has a "bcrypt" 
subdirectory? That will break things.

Does this work on Python 3? I'm on Python 3.3.2 and I'm getting the same error 
message.

Nevermind, just found this. Would be nice if this was in the main tree.

tip does work from python-3. See 
https://code.google.com/p/py-bcrypt/wiki/ReleaseNotes_0_4 for the release 
that's coming in a week or so.

wrt comment #3 - I just tried on pypy (stable and tip, non-JIT) and the module 
(at tip) imported okay but fails. It looks like PyArg_ParseTupleAndKeywords() 
is broken somehow - it returns success but doesn't actually fill in the string 
arguments or their respective lengths.

I'll try again with the JIT version of pypy in case that makes any difference; 
it seems to be what most people use.

No change with JIT version. Browsing the pypy code, PyArg_ParseTupleAndKeywords 
is implemented in ./pypy/module/cpyext/src/getargs.c and "s#" arguments are 
supported by convertsimple(). 

I'll file a pypy bug and see what happens.

https://bugs.pypy.org/issue1569 filed - it looks like 's#' arg parsing is 
returning garbage on my pypy
