Installing/Using Terminal Block Generator on current MacOS

Hi everybody,

thank you all for this marvelous piece of software.  I was looking for software to draw my electrical wirings in my workshop and found qeletrotech.  I am working an a MacOS (10.15.4).  I found it on Thursday and now my actual project has over 10 folios and nearly 200 parts.  Learning qelectrotech was easy to me and I am impressed by its functionality.  So very well done!

I also tried the Terminal Block Generator plugin.  I found the menu entry and clicked on it.  A new window opened, saying, that I had to download the package "pip3 install qet_tb_generator", which I did.  (In fact, I am running Python 3.7.7, installed from Homebrew.)

Next I again clicked on the menu button, but still the same notice appeared. :-(

I was able, to start the qet_tb_generator from the shell/terminal.  It starts and asks for a .qet file to process.  (I can also add a filename, while starting it from the shell prompt.  Then the file seems to be loaded directly.)

In either cases, the application starts its own window and presents the help, how to operate it.  I can also click on the "Create Terminal Blocks" button, but the best I can get, is an error message, that I first have to select the terminals.  But there are no terminals, there is no window, to select from, ...

I tried to read all the related articles in this community forum, except those on french, which I am not able to speak.  Pardon.

There where some issues in the past, regarding installation and usage from MacOS; the most recent ones originating from 2018.Neither of the given solutions where appropriate to my.  (E. g. I don't have any /Applications/Framework/Python ..., or whatsoever was suggested. :-()

This is the best, I can get, see attachment #1.
