Running RPS with pyrevit forms not working under ironpython 3.4

[roy_M]

Hi,

I am new with RPS and python scripting but was wondering if there is a way to set RPS to run using ironpython 2.7 instead of using the later version?

I tried to use and import pyrevit.forms libraries and always getting this exception below. 

   Exception : System.Exception: PyRevitCPythonNotSupported   

For some reason, my RPS Ironpython version has been changed to 3.4.0 from 2.7.0. The older version did not have any problem running the pyrevit libraries. 

 

I would appreciate any help.

Thanks.

Use an older release, like 1.0.2. I am guessing you are having problems because 2.0.0 added support for IronPython 3.4, but pyRevit is still in Python 2. https://github.com/architecture-building-systems/revitpythonshell/releases
