[Qgis-user] Couldn't load plugin contour due an error when calling its classFactory() method

[Chris Crook]

HI Paulo

I'm not familiar with the MacBook and configuring QGIS on it, but the problem is that the contour plugin uses a python module called matplotlib, and that in turn uses a python module called pyparsing.  The error message is saying that the pyparsing module is missing.
Unfortunately I cannot help further than that.  The pyparsing module is available at http://pyparsing.wikispaces.com/Download+and+Installation
but how you install it depends on how your python installation is set up.

When you have fixed this there may be another couple of python dependencies you may need to install, listed at
http://matplotlib.org/users/installing.html

Good luck
Chris

Hi Everybody,

I ' m a newcomer to QGIS and I'm finding so problems in running some of its plugins.

I have Qgis 1.8.0 - Lisboa, running on a MacBook Pro with OSX 10.6.8 (Snow Leopard).

On trying to load the "Contour" Plugin, I get the message below. Can anybody help me ?

On waiting for your answers, I thank you all in advance.

All the Best.
