Previously i was getting the error <br>
<br>
No module named PyQt4.QtCore and PyQt4.QtGui <br>
<br>
But after installing the PyQt inside the site package it is not <br>
showing any error now. <br>
<br>
<br>
Now i have started getting the error, <br>
qgis. core module not found. <br>
qgis.gui module not found. <br>
<br>
I have done whatever way possible from my side. <br>
<br>
My system environment is as follows: <br>
<br>
OS -- Windows 2000 <br>
Python 2.5 <br>
PyQt <a href="http://4.4.3.1">4.4.3.1</a> <br>
QGIS <a href="http://0.11.0.2">0.11.0.2</a> <br>
<br>
I dont know in which step i should be installing these one after other. <br>
and also where to install and how to compile <br>
<br>
It will be very kind of you if you can help me out. <br>
<br>
Bye <br>
