It's hard for me to know what you want to convey with these long transcripts. It would be better if they were edited, or at least if you would point out results that you don't like or don't understand. But I can see a few things, I think:
1. Installing Leo's dependencies using pip -r requirements.txt does not install Leo itself. It does not create those scripts in the venv's bin directory. It only installs the modules and packages that Leo needs. You have to install Leo using pip for that (while the venv is active). For example, in my "leo" venv, which has Leo's dependencies but into which I haven't installed leo using pip, there is no *leo* script: (leo) tom@thomas-xubuntu-VirtualBox:~/venv$ ls leo/bin/ |grep "leo" # there was no result 2. Using python3 -m leo.core.runLeo, when you have cd'ed to your github's leo-editor directory, finds Leo's files because Python starts looking for files starting at the current directory. If you export the PYTHONPATH shell variable, then Python will start by looking there. That's why I recommend using a script that sets the variable. Then you don't have to remember to cd to the right directory first. 3. Even after you have activated your venv, the shell will not find its *leo* script because there isn't one. It won't be there unless you pip-install Leo while the venv is activated. The results from running *which* show that. You could also use *whereis*, and get the same result. Even if you installed Leo in the venv and started Leo using the venv's *leo* script, Leo would be using the Leo code in the venv, not the code in your github repo. 4. Your transcript shows that Leo started when you had cd'ed to its repo directory. But I can only see Leo's startup output to the console. That output looks normal. But it doesn't tell me if the Leo window actually opened and worked. Did it?

Mai 2024 um 20:05:10 UTC+2: It can be hard to be sure what the Python search path is. Here is what shows up for my system when I have activated my "Leo" VE. This VE (on Windows) is contained in the directory C:\Tom\venvs\leo. Note that on Windows you don't have to source the script. Please bear with me a bit longer, as I'm sometimes stubborn ;-) I'd like to understand, why the case of 'Leo from GitHub in a PyVE' is no longer working ? - It has worked on Linux (Debian & Fedora) up until Leo version 6.7.7 (maybe evern 6.7.8) ! I'd like to do that, before creating an **additional personal** script, since I still believe it should be part of Leo's GitHub repository ... I did use your advice to check Python's search path, etc. - Here are the results for the three relevant cases in my Debian 12 VM: * Check out Python's search path with Leo outside of any PyVE - See "Log-001". * Check out search path in Leo's PyVE from PyPI - See "Log-002". * Check out search path in Leo's PyVE from GitHub - See "Log-003". Note 1: The first variation is necessary for me to address Leo-Integ issue # 299 <https://github.com/boltex/leointeg/issues/299>. Note 2: The answer to my question has to do with the fact that no 'leo' module is found in '/home/user/PyVE/GitHub/Leo/bin' - See "Log-003" ...
