Re: New version of Spontini-Editor with many new features

[Knute Snortum]

This is my experience with installing Spontini:

$ python3 SpontiniServer.py
Traceback (most recent call last):
  File "SpontiniServer.py", line 32, in <module>
    from tkinter.messagebox import showerror
ModuleNotFoundError: No module named 'tkinter'

installed python3-tk, then...

2021-01-02 14:32:54 [E] The virtual environment was not created
successfully because ensurepip is not
2021-01-02 14:32:54 [E] available.  On Debian/Ubuntu systems, you need
to install the python3-venv
2021-01-02 14:32:54 [E] package using the following command.
2021-01-02 14:32:54 [E]
2021-01-02 14:32:54 [E]     apt-get install python3-venv
2021-01-02 14:32:54 [E]
2021-01-02 14:32:54 [E] You may need to use sudo with that command.
After installing the python3-venv
2021-01-02 14:32:54 [E] package, recreate your virtual environment.

$ which pip
$ which pip3
/usr/bin/pip3
$ which venv
$

At this point it may be my installation of venv that is bad.

$ locate venv
...
$ /usr/bin/pyvenv
$ ll /usr/bin/pyvenv
lrwxrwxrwx 1 root root 10 Mar 13  2020 /usr/bin/pyvenv -> pyvenv-3.8
$ locate pyvenv-3.8
...
/usr/share/bash-completion/completions/pyvenv-3.8
$ ll /usr/share/bash-completion/completions/pyvenv-3.8
lrwxrwxrwx 1 root root 6 Feb  1  2020
/usr/share/bash-completion/completions/pyvenv-3.8 -> pyvenv

So the link reference is circular. I'm not even sure who to report
this to.  But there you have it.
