Unable to import SimPy
Question: I am new to SimPy I used the easy_install to install SimPy module then on the
command line I simply tried `from SimPy.Simulation import *` but I get the
following error

    
    
    Python 2.6.7 (r267:88850, Aug 22 2011, 14:13:38) 
    [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
    Type "help", "copyright", "credits" or "license" for more information.
    >>> from SymPy.Simulation import *
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    ImportError: No module named SymPy.Simulation
    

I use easy_install to install packages, I have simplejson install without any
problem and when I import simplejson I don't get the above error. I did an
update and easy_install successfully updated the SymPy module yet I still cant
import the SimPy Module

    Best match: SimPy 2.2
    Processing SimPy-2.2-py2.6.egg
    SimPy 2.2 is already the active version in easy-install.pth
    
    Using /Library/Python/2.6/site-packages/SimPy-2.2-py2.6.egg

    Finished processing dependencies for SimPy
    

I also check the `easy-install.pth` file, and looks like everything has been
added properly.

    
    
    [/Library/Python/2.6/site-packages]$more easy-install.pth 
    import sys; sys.__plen = len(sys.path)
    ./simplejson-2.1.3-py2.6.egg
    ./SimPy-2.2-py2.6.egg
    import sys; new=sys.path[sys.__plen:]; del sys.path[sys.__plen:]; p=getattr(sys,'__egginsert',0); sys.path[p:p]=new; sys.__egginsert = p+len(new)
    

It will be great if I could get any help on this.

Best; NH
