<p>well,</p>
<p><br>
</p>
<p>This is what I see with a print statement at the beginning of
mcgui.py<br>
</p>
<p>PyQt5.__file__ :
/home/jfmoulin/.local/lib/python3.8/site-packages/PyQt5/__init__.py<br>
</p>
<p>So, yes, this is my pip installed Qt<br>
</p>
<p> <br>
</p>
<p>Trying your sugestion:<br>
</p>
<p> jfmoulin@jfm17:~$ mcstas-2.7.1-environment <br>
<br>
The new shell started here is now set up for running this
version of mcstas:<br>
<br>
McStas version 2.7.1 (Oct. 04, 2021)<br>

1997-2021<br>

<br>
To end using this version of mcstas, exit this shell.<br>
---- (in this same shell)<br>
</p>
<p> jfmoulin@jfm17:~$ mcrun<br>
<br>
Command 'mcrun' not found, did you mean:<br>
<br>
command 'mcron' from deb mcron (1.0.8-1build1)<br>
...</p>
<p>so, still no joy. <br>
</p>
<p>I tried here under 2.7.1 which is the one I installed after
having the problem with 3.1 in the first place.</p>
<p><br>
</p>
<p>And, BTW, what is a desktop launcher ;0) (i.e, I called mcrun
from a shell as reported in my previous mail. No clicking, I
swear.)<br>
</p>
<p>Moreover, I seem to be stuck in the perl past for mcrun:<br>
</p>
<p><br>
</p>
<p> jfmoulin@jfm17:~$ which mcgui<br>
/usr/share/mcstas/2.7.1/bin/mcgui<br>
--------------------------------------------------------------------------------</p>
<p> jfmoulin@jfm17:~$ ls /usr/share/mcstas/2.7.1/bin/<br>
cif2hkl mcformat mcpl2ssw mcstas
postinst<br>
mcdisplay-mantid.pl mcgui mcpltool mcstas_errmsg
