uv - install python 3.12 with tcl8.6?

[josmithua]

This is more of a uv question, but relates to this project:

I need to use python 3.12 with tcl8.6. Currently when I install python 3.12:

uv python install 3.12

It installs tcl9:

~/.local/share/uv/python/cpython-3.12-macos-aarch64-none
➜ ls lib
itcl4.3.5/           libtcl9.0.dylib*     pkgconfig/           tcl9/                thread3.0.4/
libpython3.12.dylib* libtcl9tk9.0.dylib*  python3.12/          tcl9.0/              tk9.0/

tcl9 breaks my macOS Python app, but 8.6 works fine. Is there a way I can install python 3.12 with tcl8.6?

Thanks!

Older patch versions of 3.12 include Tcl 8.6, for example 3.12.11. This can be installed using:

uv python install 3.12.11

Note that new releases will all use Tcl 9. Older patch releases do not get bug fixes or updates.

@jjhelmus Thank you! For now I will have to use python 3.12.11. Is there any way to "swap out" tcl versions so we can use newer versions of Python with older versions of tcl?

Check your assumptions bro.

Really? Have you tried using Python 3.13 or newer and seeing if that fixes your issue? It's better to move forward than backwards.

Thank you, wise one. Using Python 3.13 resolves the issue 🙏
