help, installing matplotlib on mac 10.8

Hi Charles,

I'm sending my reply to the matplotlib-users list - please follow
up there, so that others benefit from your experience, or folks
who have run into the same issue can also pitch in with their
help.

Here's where to go to sign up:

Once you're signed up, you hit "reply all" to this email (it
would be kind of you to remove my name from the addressee list
when you do that, so that the email goes only to the
matplotlib-users list, of which I'm a member)

See the rest of my reply below your original message.

This looks like conflicting versions of python are being used (64
bit and 32 bit). One trick for getting to the bottom of Python
stack traces is to take the text of the *last* line of the
traceback, remove all but the last few bits of the file path
(since other folks won't necessarily be installing to the extact
path you've installeed to), and feed it to google.

The first google hit for "_path.so: no matching architecture in
universal wrapper" is this stackoverflow post:

See if the solution suggested there (installing 32-bit version
from python.org)

best,

many thanks Paul,

this did work:

I uninstalled all python in my computer:

sudo rm -rf python*
sudo rm -rf /Library/Frameworks/Python.framework/Versions/2.7
sudo rm -rf "/Applications/Python 2.7"

and installed python and matplotlib afresh. Numby had been installed

Python 2.7.4 (v2.7.4:026ee0057e2d, Apr 6 2013, 10:15:50)
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

import numpy as np
import pylab as pl
x=[1,2,3,4]
y=[2,3,4,5]
pl.plot(x,y)

[<matplotlib.lines.Line2D object at 0x50b8990>]

pl.show()

Thank you,

Charles
