[mcstas-users] Fwd: Pyqt problem on fresh install

[Jean-Francois Moulin]

Hello,


I just tried a fresh install of mcstas on a linux mint box and could not 
start mcgui. The backtrace seems to point to a conflict with the 
installed pyqt5:


Original exception was:
Traceback (most recent call last):
   File "/usr/share/mcstas/2.7.1/bin/../tools/Python/mcgui/mcgui.py", 
line 945, in <module>
     main()
   File "/usr/share/mcstas/2.7.1/bin/../tools/Python/mcgui/mcgui.py", 
line 935, in main
     mcguiApp.ctr = McGuiAppController()
   File "/usr/share/mcstas/2.7.1/bin/../tools/Python/mcgui/mcgui.py", 
line 417, in __init__
     self.view = McView()
   File "/usr/share/mcstas/2.7.1/tools/Python/mcgui/viewclasses.py", 
line 23, in __init__
     self.ew = McCodeEditorWindow()
   File "/usr/share/mcstas/2.7.1/tools/Python/mcgui/viewclasses.py", 
line 281, in __init__
     self.__initScintilla()
   File "/usr/share/mcstas/2.7.1/tools/Python/mcgui/viewclasses.py", 
line 471, in __initScintilla
     from PyQt5 import Qsci
ValueError: PyCapsule_GetPointer called with incorrect name



I tried both 2.7 and 3 versions, both show the same behaviour.


For Info, pip3 list returns the following

PyQt5                                5.15.6
PyQt5-Qt5                         5.15.2
PyQt5-sip                          12.9.1


Any help appreciated!

Jean-François
