Error: No module named 'PyFlow.Packages.PyFlowFreeCAD'

[SuzanneSoy]

Hi!

I followed the installation instructions in the README (cd ~/apps/freecad/.FreeCAD/Mod; git clone https://github.com/microelly2/PyFlow; suzanne git clone https://github.com/mottosso/Qt.py; git clone https://github.com/microelly2/NodeEditor). The check for the imports seems good:

but when I click create all Nodes for Test from the menu tests, I get the following error:

Running the Python command 'Micro_createAllNodesforTests' failed:
Traceback (most recent call last):
  File "<string>", line 199, in Activated
  File "<string>", line 1, in <module>
  File "/home/suzanne/apps/freecad/.FreeCAD/Mod/NodeEditor/nodeeditor/Commands.py", line 1202, in createAllNodesforTests
    from PyFlow.Packages.PyFlowFreeCAD.Nodes.FreeCAD_Coin import nodelist

No module named 'PyFlow.Packages.PyFlowFreeCAD'

Just in case the instructions were supposed to be followed to the letter, I tried without the implicit step of creating a new document, and get an error because there is no FreeCAD.ActiveDocument.

I noticed I have a folder .FreeCAD/Mod/NodeEditor/PyFlowPackages but not .FreeCAD/Mod/NodeEditor/PyFlow/Packages (notice the slash before Packages), so I tried making a copy with (cd ~/apps/freecad/.FreeCAD/Mod/NodeEditor && mkdir PyFlow && touch PyFlow/__init__.py && cp -ai PyFlowPackages PyFlow/Packages). That seemed to help, and it fails much later:

I was able to create some nodes by clicking, but it seems I can't get any constant to work nor any FreeCAD nodes to work.

I'm running the latest FreeCAD AppImage:
