<![CDATA[Running 1.8 beside 3.3]]>I am making the transition from 1.8 to 3.3 but still have 1.8 in operation until a project started there is completed (soon). Is it possible to run these two versions together? I get traceback errors when trying to update extensions in 3.3 via Mechanic2 which I believe are related to 1.8 utilising the 1to3 extension. This seems to be confusing 3.3 and not allowing updates to take place...

Below is a snippet of the output when attempting to update:

Installing '1To3' report:
  Traceback (most recent call last):
      File "main.py", line 9, in <module>
      File "/Users/joesquared/Library/Application Support/RoboFont/plugins/1To3.roboFontExt/lib/RF3.py", line 12, in <module>
    ModuleNotFoundError: No module named 'ufoLib'

Installing 'Add Overlap' report:
  Traceback (most recent call last):
      File "AddOverlap.py", line 3, in <module>
    ModuleNotFoundError: No module named 'ufoLib'

Am I better off waiting to make the jump until I can remove 1.8, or am I missing something simple?

Thanks!

Works for me. Supports 3.3 and looks to have a RF1 contingency built-in:

try: # RF3
    from fontTools.pens.pointPen import AbstractPointPen
except: # RF1
    from robofab.pens.pointPen import AbstractPointPen

I have tried to uninstall the extensions that won’t update but, that is also failing...

you can configure different folders for extensions in each version of RF, so you can keep your 1.8 setup and start fresh on 3.3 – see this thread for more info.

hope this helps! cheers
