I work in an environment where both the program files for QGIS as well as the connection to the Plugin repository are blocked. Is there a way that I can point QGIS to look in an alternative directory for python plugins. I can see that this is possible for C++ plugins but fail to see an option for Python ones.
There is an start option for QGIS called configpath. You can change it by editing the batch file in the bin directory, which calls qgis. The last line should look like this:
start "QGIS" /B "%OSGEO4W_ROOT%"\bin\qgis-ltr-bin.exe --configpath %HOME%\.qgis2 %*
If you don't have write access to the directory (normally C:\OSGeo4W\bin) you should be able to copy the batch file to your user directory. Because it is important to execute
o4w_env.bat, the second line must be changed also and include the absolute path to
Please make sure, you change it to the path on your system.
If you want to inform the system adminstrator about your issue, there is a blog article about installing QGIS on a Windows share: http://www.qgis.nl/2014/04/22/qgis-in-de-klas-onder-windows/?lang=en
