Packages installed using addon manager not showing up in the code

[davesrocketshop]

This can be difficult to reproduce. If a package is installed locally, as in for development, this problem is masked. In order to reproduce, I had to create a fresh virtual machine with no FreeCAD installed. With that in mind, do the following:

1. Install FreeCAD
2. Using the Addon Manager, install the Rocket WB.
3. When prompted, include the optional installs: CfdOF, shapely, and python-docx
4. Restart

Checking the AdditionalPythonPackages folder, all packages are in there. However trying to load them using the Rocket WB produces module not found errors. This can be shown from the Python console:

Not that uninstalling and reinstalling the WB has no effect. As far as it sees, the packages are already installed, but they're still not visible to the addon.

[chennes]

Can you tell me more about the system? I can't reproduce the issue on Windows, I just get:

>>> import shapely
>>> from shapely import Point
>>> from docx import Document
>>> 

(which is to say, it works as expected -- neither of those packages are available elsewhere on the system, they're only in AdditionalPythonPackages). So there's something going wrong with PYTHONPATH. Can you try:

import sys
for path in sys.path:
    print(path)

[davesrocketshop]

I don't see it in my local install either which is why I created a fresh virtual machine. Many users are reporting this issue though.

[chennes]

And in C:\Users\User\AppData\Roaming\FreeCAD\AdditionalPythonPackages\py311 you have:

...
shapely
shapely.libs
shapely-2.1.2.dist-info
...

?

[chennes]

Do you get any output for import shapely; shapely.__version__?

[davesrocketshop]

Yes to the files and no to the version. It does show 2.1.2 in the files though.

I'm currently resetting my VM so checking things will take a few minutes. (Mickeysoft is slow!)

[davesrocketshop]

Well, in really annoying news, trying the process from scratch has everything loading correctly.

It didn't before, and as mentioned others are seeing this issue. Not sure what's going on

[chennes]

Can you ask your other bug reporters to gather the same bits of output? sys.path, directory contents, output of import shapely; shapely.__version__?

[davesrocketshop]

Aanndd... it's back. Closed and reopened FC and I now get the error.

[chennes]

Re-run in safe mode?

[chennes]

And for giggles, let's also confirm:

>>> from freecad.utils import get_python_exe
>>> get_python_exe()
'G:\\FreeCAD\\FreeCAD\\cmake-build-relwithdebinfo-visual-studio\\\\bin\\python.exe'
>>> 

[davesrocketshop]

In safe mode:
ModuleNotFoundError: No module named 'shapely'

[davesrocketshop]

C:\Program Files\FreeCAD 1.0\bin\python.exe

[chennes]

Ah damn, Safe Mode doesn't tell us anything, AdditionalPythonPackages is disabled there. So, if I am understanding your process with the VM:

1. New VM. Install FreeCAD. Launch it.
2. Install Rocket and all deps.
3. Restart FreeCAD, import shapely; shapely.__version__ gives 2.1.12
4. Restart FreeCAD, import shapely; shapely.__version__ gives an import failure?

[davesrocketshop]

Correct.
