No module named pyrevit

I’ve installed pyrevit 4.8.13 in Revit 2022 and wanted to test a script
but in Dynamo I get this error “No module named pyrevit”


Do I need to install or configure other things?
I searched for information but i can’t find it.
Can someone please help me?

Hi! Are you just getting started with pyRevit? I ask because I haven’t seen it be referenced in a Dynamo script before. Though maybe that’s in the works?

Here’s a similar thread: Import pyrevit in dynamo node - Dynamo

And here’s a great place to get started with pyRevit: Notion – The all-in-one workspace for your notes, tasks, wikis, and databases.


I don’t understand your answer & links and/or could not find the solution.
I’ve installed pyRevit with this page ( and got no errors. (see log-file)

The script is given bij Erik Frits - link:
A far as I know is the script complete with no missing ‘actions’.

I started Revit Dynamo and added the text in a python-node (IronPython 2)

from pyrevit import script

output = script.get_output()

# assuming element is an instance of DB.Element

Then a Run the script and got the error ‘No module named pyrevit’.
Why does it not work?

Sorry, I should have been more clear. I don’t think pyRevit runs in Dynamo. Please read the “getting started” info in the second link I posted. Also, try searching “getting started with pyRevit” on YouTube and then follow along with a tutorial.

you can’t do that.
pyrevit modules are not compatible or designed to be used in dynamo.
The way you could expect to make it work is the following, but it won’t work.

import sys
from pyrevit import revit

doc = revit.doc

As mentioned by @scartmell the two beasts: Dynamo and pyRevit, live in paralell universes

If you want to try a dynamo python script with references to dynamo libraries → Dynamo
if /// … pyrevit libraries → pyRevit

If you want to create buttons for testing purposes, I suggest you activate the Bundle Creator Extension, follow the instructions of the button, then al+click to locate the script of the new button and try your code from there.

This video helped me getting started with creating my own toolbars.
It has a good step-by-step explination for the basic structure

Thanks @scartmell @Jean-Marc @MelleH

(Never realized that pyRevit does not work in Dynamo.)
