Freecad-daily initialization error

Post by mrwusel » Wed Sep 23, 2020 5:57 am

I installed FreeCAD-daily from the daily ppa:

Code: Select all

OS: Ubuntu 20.04.1 LTS (KDE/plasma)
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.19.
Build type: Release
Branch: unknown
Hash: ec5bbad6261a7370eb4f5794439cacef643f68a3
Python version: 3.8.2
Qt version: 5.12.8
Coin version: 4.0.0
OCC version: 7.3.0
Locale: German/Germany (de_DE)
When I start FreeCAD I get error messages shown below:

The Pathworkbench isn't working for me either. When I switch to the workbench and try to create a Path object:

I haven't tested all workbenches but some of them work fine like the part and part design wb.

I think the problem occurs when trying to load any of the compiled resource files, meaning Draft_rc.py, Arch_rc.py, etc.

These resource files are compiled by Qt from SVG icons, .ui files, translations, etc.

This error was reported when Ubuntu 20.04 was newly released because there was a mismatch between PySide2 and Qt5, I think.

There are some threads about it; I think the solution was to install some the packages from Qt5 containing the resource compiler, called "rcc", or "python3-pyside2-rcc", or "python3-pyqt5-rcc", or something similar.

What's the status on the above post?

I think the problem was that Qt5 did not match the version of PySide2, so the solution was to use PyQt5 to compile the resource files? But this seems to embed the requirement for PyQt5 inside the resource files (Draft_rc.py) or something like that.

Judging by this path:

/usr/local/lib/python3.8/dist-packages/PyQt5/QtCore.so

particularly the /usr/local part, it looks like you have an additional installation of PyQt5 that is conflicting with the system one. Did you perhaps sudo pip3 install that?
Like my FreeCAD work? I'd appreciate any level of support via Patreon, Liberapay, or PayPal! Read more about what I do at my blog.

Thanks! I could fix the problem. Totally missed /usr/local.
