Iyi gunler Cem Bey, I have just installed QGIS 2.6 (Brighton) on my PC (Bootcamp) running Windows 7 and would like to try out FlowMapper. However after I have loaded it I received the following error:

Error Loading Plugin The plugin seems to be invalid or have unfulfilled dependencies. It has been installed, but can't be loaded... Here is the error message below:

The plugin is broken. Python said: ascii

Can you please help me solve this riddle?

  • I'd start python console and 'import ogr' command give errors! It's not a flowmapper pluging error seems more deeply programs.

Resolved! It's a module PATH Python console problem.

In QGIS Brighton/apps/Python27/Lib/site-packages create osgeo.pth (Administrators) file and put

# .pth file for the osgeo extensions osgeo

start QGIS and install flowmapper ;)


Merhaba Başak Hanım,

You could try manual installation if you are experiencing issues with automatic installation by using QGIS Plugin Manager.

FlowMapper is designed to be compatible with Windows, MacOS* and Linux platforms. It other words it has cross platform support. (*filtering options do not work under macos unless gdal/ogr dependencies are installed)

To manually install FlowMapper please copy FlowMapper folder under the OS specific path given below. Afterwards, restart QGIS and enable the plugin from plugin manager.

C:\Program Files\QGIS Dufour\apps\qgis\python\plugins\
