Can't use tkinter with new venv set up with uv #7036
Description
(Maintainer edit)
NOTE If you are still affected by this, try reinstalling the managed Python interpreter
python install --reinstall ...
uv venv
source .venv/bin/activate
python -c "from tkinter import Tk; window = Tk()"
This gives me the error message:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/Users/dstansby/.local/share/uv/python/cpython-3.12.5-macos-aarch64-none/lib/python3.12/tkinter/__init__.py", line 2346, in __init__
self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
_tkinter.TclError: Can't find a usable init.tcl in the following directories:
/tools/deps/lib/tcl8.6 /Users/dstansby/.venv/lib/tcl8.6 /Users/dstansby/lib/tcl8.6 /Users/dstansby/.venv/library /Users/dstansby/library /Users/dstansby/tcl8.6.12/library /Users/tcl8.6.12/library
This probably means that Tcl wasn't installed properly.
I can successfully run python -c "from tkinter import Tk; window = Tk()" in a fresh conda environment, but when I install python on conda it also installs tk, so maybe that's why it works? Maybe this isn't an issue with uv?, but if anyone knows how to get this working I'd be very gateful!
