Thonny not starting

I just installed Thonny using sbopkg on my laptop and it will not load.

When I click the Thoony icon on the start menu Thommy appears on the bottom of the screen for a minute then disappears.

The install went ahead with no errors.
I'm running 14.2 and a KDE Desktop.

This?

Thonny comes with Python 3.7 built in

Do you have different versions of python on your machine now? Did you have python installed before?

What is the output of

Code:

python

#or

python3

And what error does thonny give if run in terminal.

Ok, you have python2 installed. How about python3? It says that thonny is python3.
What does thonny in the terminal say? Is python3 in your $PATH?

Find out why thonny dies.

I installed Python3 and it made no difference

here is my path:

python3 seemed to install OK with no errors however it clearly has not installed.
What would stop it being installed yet bring up no errors?

you need to start python3 with the command python3 (instead of python, which defaults to python2).
I don't really know how did you try to start thonny, but probably

Code:

pip3 install thonny

thonny

or something similar will work. But probably you need to install tkinter (python3-tk) too.

SAJM	07-01-2022 12:32 AM

Interesting that Tkinter is not included in sbopkg or slackpkg - is that telling me something?

SAJM	07-01-2022 05:03 AM

Code:

pip3 install thonny

thonny

result

Code:

bash-4.3# pip3 install thonny > thonny.txt

You are using pip version 18.1, however version 22.1.2 is available.

You should consider upgrading via the 'pip install --upgrade pip' command.

bash-4.3# thonny

I dont get it
On KDE nothing loads
No Python2, no Python3 and no Thonny

On the treminal both Python 2 & 3 open

Thonny does not.

I wish I knew what this means:

You probably don't have tk/tcl installed. tkinter uses that.

Start with some basics.

In a terminal, can you open a python3 shell. You already established that you have python2 working.(post3-7)

Find out where python3 is. And if your shell have a PATH to the executable. Looks like it does.

Example: (arch)

Code:

python

Python 3.10.5 (main, Jun  6 2022, 18:49:26) [GCC 12.1.0] on linux

Type "help", "copyright", "credits" or "license" for more information.

>>>

Code:

which python

/usr/bin/python

Until you have a working python3, nothing will work.

Then in the working python3 shell

Code:

python

Python 3.10.5 (main, Jun  6 2022, 18:49:26) [GCC 12.1.0] on linux

Type "help", "copyright", "credits" or "license" for more information.

>>> import tkinter

>>>

If you get an error, you'll need to fix it. What is the error to that?

In python2 it was Tkinter, in python3 it is tkinter.

Edit:
You need to troubleshoot this a step at a time.

I wish I knew what this means:

It means that the python3 interface for TK is missing.

Maybe python3 was compiled without TK support.

So it seems it could be installed with :

> pip3 install tk

Here is the source. Which is where you would first look, if you are trying to build something.
https://github.com/thonny/thonny

Look at the error in post #12

Code:

File "/usr/lib64/python3.7/site-packages/thonny/config.py", line 9, in <module>

import tkinter as tk



File "/usr/lib64/python3.7/tkinter/__init__.py", line 36, in <module>



File "/usr/lib64/python3.7/tkinter/__init__.py", line 36, in <module>

import _tkinter # If this fails your Python may not be configured for Tk

ModuleNotFoundError: No module named '_tkinter'

That would be here
https://github.com/thonny/thonny/blo...onny/config.py

And here
https://github.com/thonny/thonny/blo...ny/__init__.py

You don't have tkinter working. Start with fixing that. Show what eroors you are getting step by step. Or you will never get anywhere.
