error when installing python parsley

Question

I'm trying to install parsley, a parser written in python, but I'm stuck at the first hurdle. I can't even install it. I'm on windows 7, using cygwin.

And this version of python: $ python3 -V Python 3.4.2

$ pip install Parsley

Cleaning up...

Then in python's IDLE:

>>> import parsley
Traceback (most recent call last):
  File "<pyshell#5>", line 1, in <module>
    import parsley
  File "C:\Python34\lib\site-packages\parsley.py", line 86
    except ParseError, e:
                     ^
SyntaxError: invalid syntax

What am I doing wrong?

Parsley (1.2 for now) does not support Python 3.x.

You need to use Python 2.x to use the package.
