_tkinter.TclError: can't find package Thread about tkthread HOT 4 CLOSED

Try installing the tcl-thread package. I ran into this same issue on Raspbian.

from tkthread.

Thanks a lot.
apt-get install tcl-thread
did the trick for python3 (I was only searching for tk, not tcl). And the packages works beautifully with python3, there is almost no delay when updating from a background thread, nice! Exactly what I was looking for, an implementation of runOnUiThread or invokeLater or however it is called in other GUI frameworks.

However, I do not know how to proceed for pypy (where the package is really needed!) and i don't know anything about tcl. I have seen that tcl-thread install also /usr/lib/tcltk/x86_64-linux-gnu/thread2.8.2/libthread2.8.2.so in addition to some tcl files and apparently pypy has its own tcl/tk and still complains about a missing Thread package.

If that works it should really become part of the standard library...

from tkthread.

ok, i just blindly copied the entire installation directory of tcl-thread into the pypy installation and that worked.
cp -rp /usr/lib/tcltk/x86_64-linux-gnu/thread2.8.2 /opt/pypy3.6-7.1.1-beta-linux_x86_64-portable/lib/tcl/
Might not be clean, but I don't complain. It works as smoothly and fast under pypy as under python3.

Having tkt in the standard (or call it invoke_later or whatever) would make tkinter much more usable for all people that do know other UI frameworks and threading. Thanks for the package.

Is there a way to get this working on Windows 10, as it is in Linux shown above?
