Looks like you ran into issue
https://github.com/leo-editor/leo-editor/issues/1453. I just posted a
comment there stating that the attempted fix for that issue did not work.

You were right with your assumption. - I tried it both with Leo 6.1-final 
as well as 6.2-b1-devel - and - it works as you suspected.

In both cases it does throw a type error related to ...\spellCommands.py - 
but - it does open the workbook.leo outline.

Thanks a lot for your explanation!

With kind regards,

Viktor

Most likely Tkinter is used only to ask user for leo-id if there is no one 
to be found. It is located in the ~/.leo folder. When you restore your 
folder, Leo knwos your leo-id and doesn't need to ask you so there is no 
need for Tkinter.

Try adding an empty ~/.leo folder and put the `.leoID.txt` file inside, and 
in this file just write your login name.

Analyzing Leo's content & dependencies a bit more, I found at least one
reason myself:

* Leo does support the GUI-Options: [ browser | console | null | qt ] - and
- at least the console option does require 'tkinter' as well.

So this now looks only like a possible future 'refactoring' task to me, in
case a split into smaller sub-components/-packages is ever planned for Leo
...

This is the remaining question I'd really would like to get an explanation.

With kind regards,

Leo requires tkinter module to be configured in Python environment

[Viktor Ransmayr]

Hello Edward, hello Matt,

I just noticed something interesting/ strange/ weird.

Actually two issues:

First: Leo requires that the tkinter module is configured in the Python 
installation.

(Backgound: I just upgraded to Python 3.7.6 - and - decided to de-select 
everything but pip ...)

Second: I noticed this only, when I started w/o an existing '~/.leo' 
directory.

The traceback I receive is:

(Leo-devel) PS C:\Users\Viktor\pyve\github\Leo-devel> leo-m

--global-docks: False

Traceback (most recent call last):

(Leo-devel) PS C:\Users\Viktor\pyve\github\Leo-devel>

As soon as I re-use my previously saved '~/.leo' directory, the 
ModuleFoundError disappears ...

Can you please explain 

* why the module 'tkinter' is required, although PyQt is used as the GUI 
framework - and - 

* secondly, why the problem goes away, if I'm using "old/ saved" '~/.leo' 
content ...

With kind regards,

Viktor
