[SOLVED] Python Turtle Shows Blank Screen

Hi Guys, 

Recently, my python turtle shows blank screen when running, but before that, the shell shows below warning message. (by the way I use macOS Monterey 12.4, and python 3.10.4, pyenv 2.3.0) 

"The system version of Tk is deprecated and may be removed in a future release. Please don't rely on it. Set TK SILENCE DEPRECATION=1 to suppress this warning."

from above warning, we know that tk version is older than the tcl-tk which python 3.10.x use, and I guess this problem cause the python turtle shows blank screen like this 👇🏻

Python Turtle shows Blank Screen

SOLUTION

Since I use pyenv to manage my python installations, so here is what I did:

1. Uninstall current python in pyenv

$ pyenv uninstall 3.10.4

2. Update / Install tcl-tk using brew

$ brew install tcl-tk
$ brew info tcl-tk
tcl-tk: stable 8.6.12 (bottled) [keg-only]

3. Install python using pyenv again with env variables tcl-tk like these 👇🏻

$ env \           
  PATH="$(brew --prefix tcl-tk)/bin:$PATH" \
  LDFLAGS="-L$(brew --prefix tcl-tk)/lib" \
  CPPFLAGS="-I$(brew --prefix tcl-tk)/include" \
  PKG_CONFIG_PATH="$(brew --prefix tcl-tk)/lib/pkgconfig" \
  CFLAGS="-I$(brew --prefix tcl-tk)/include" \
  PYTHON_CONFIGURE_OPTS="--with-tcltk-includes='-I$(brew --prefix tcl-tk)/include' --with-tcltk-libs='-L$(brew --prefix tcl-tk)/lib -ltcl8.6 -ltk8.6'" \
  pyenv install 3.10.4

4. Done
