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?

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

What is the output of
And what error does thonny give if run in terminal.

Here is what I got

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:

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?

and

....however if I ls packages, python3-3.7.2-x86_64-1_SBo is listed.

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

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

result

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)
Until you have a working python3, nothing will work.

Then in the working python3 shell
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.

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
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.

How exactly did you install it? Please describe the exact sequence of actions that you performed. Did you just start sbopkg, searched for "thonny", then installed it? If so, it's very likely that it's the wrong way to do it, in either 14.2 or 15.0. If you go to the corresponding page on SBo http://slackbuilds.org/repository/14.2/python/thonny/ you will see that it has build dependencies. Hence, you need to generate the queue file for it:

Then start sbopkg, load the queue for thonny and install all the packages, as in both thonny and its dependencies.

:( This proves that you just blindly copypasted the whole without thinking. You were supposed to do

after you did

First would check the default python version, second would explicitly check if you have python3

Again, no details about how exactly did you install Python3. And this probably implies that you did not have it already installed for something else before thonny. Then that probably you didn't go through the queue file workflow mentioned above, otherwise python3 would've been installed when you ran the queue for thonny in sbopkg.

IMHO suggesting to install software provided by SBo via pip to somebody who's not very experienced (see my copypaste comment above) will only add more confusion. Your example command will work as root, mixing stuff installed for python3 via sbopkg from SBo and software for the same python3 installed directly via pip, which is a VERY bad thing. It's possible to install things via pip as regular user, but then the pip command requires an additional --user command line argument. Yet I'm not sure using pip is needed, as I said above.

Oh please, this is Slackware, not Debian. It doesn't split python into multiple packages, adding even more confusion. If python3 was installed correctly, via the SBo script for 14.2, it contains tk, just like the vanilla python2 package. Lack of tk in python3 means that probably python3 was installed differently, hence I asked OP above to provide more details.

Please, stop suggesting pip in this context. Slackware 14.2 was the stable version for many years. You don't imagine SBo shipped python3 with no tk, considering that vanilla python2 in Slackware doesn't split the python package? See above.

How do I configure python for Tk?

As per the final error in #12 above.

I'm guessing that the standard Python install does not use Tk. Tk is something unique to Thonny

That's exactly what I did. It seemed logical and has worked in the past.
I always understood the dependencies were all installed as a package when using sbopkg

Open a python3 shell, and see if you can import tkinter. If not what is the error.

Or just keep ignoring the advise you are given.

Edit:
https://docs.python.org/3/index.html
https://docs.python.org/3/library/tkinter.html

I removed Python3 and reinstalled it paying particular attention to the output. It was very fast but I did see mention of tk flash past but it still was not installed

You are new to python. You are going to have an impossible time, unless you start at step one, then 2...

Arch calls python3 python, Slack might call that python3. It's your box, find out.

I think you will find I have already posted output from the python3 shell.

I suppose by "in the past" you rather mean "for other software". This indeed works. For software with no build dependencies. For software with build dependencies, you need to install them explicitly yourself, even if you use sbopkg. Or make use of queues, as I explained above.

No, not with sbopkg.

Not once have you posted the output of a python3 shell. You posted the output to a python2 shell. They are different.

@FlinchX says Slack calls python3.python3

Are you going to post that or not?
Then you can see if you can import tkinter in that shell. I am going to guess that you don't have tk/tcl installed. tkinter wont work without it.

Or, you could check and see if you have that installed.

After you get/have python3 working, tk/tcl installed so that tkinter will work...

Here is a simple little test script to see if all is well, with tkinter.

test.py
You can make that executable run it, or

Again, how exactly did you install it? Via sbopkg as well? Is it this Python 3? http://slackbuilds.org/repository/14.2/python/python3/

Yes. With sbopkg

@SAJM Did you have a full 14.2 install before you started to install SBo things?

Result:

[CODE}
bash-4.3$ python3 ./test.py
Traceback (most recent call last):

EDIT

oops I just noticed I should have run this after the Tk issue was resolved!!

Im going to remove everything and start again in this order

1. Install Python3
2. Install Thonny

Paying particular attention to dependencies.

Does another Slacker know what slack package contains tcl/tk? Python3.7 + comes with tkinter. But it won't work without tk.

It was a few years ago but as far as I remember, yes.

Python3 looks good
But it does not launch in the GUI, I don't know if that's a problem or not at this stage?

Still no tkinter

I do not believe pip is installed

I understood pip was installed with python?

pip now installed

OK there is some progress

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

How do I tell pip to use python3?

Here is the problem I think
Do I uninstall python2.
I didn't do that earlier in case I messed up with a dependency for an existing program

Not sure what this is telling me?

Stack overflow at
https://stackoverflow.com/questions/...d-of-python2-7

suggested:

These from the same source did not work.

python3 -m pip install tk

or

pip3 install --upgrade --force pip

That's it. I'm defeated

I could uninstall Python 2 but as I mentioned earlier I'm nervous about messing something else up that may be depending on it.

So, did you check if you have tk/tcl installed?

See my message 39
tk is installed but I think it is defaulting to python2

However when I do this:

Why did you do :
pip install tk
pip install tkinter
?

for python3 it is like I said some posts above :
pip3 install tk
and maybe :
pip3 install tkinter

pip3 is for python3 and pip for python which is python2

tkinter is only for python3

Just to verify if tk for python3 is here as it seems something is missing.

To test if Tcl and Tk are installed, you can also test if wish is present :
> which wish

tkinter is a module for Python3 which encapsulate Tcl/Tk. It needs Tcl and Tk.

So if tkinter is installed it won't work without Tcl and Tk installed.
Or tkinter is not installed.

pip3 will tell you in either case.
