Issue
The following error occurs when python -m tkinter or ʻimport tkinteris executed with python installed by pyenv. When I looked at the article on the net, it said that it could be cured withbrew install tcl-tk, but it didn't work. However, it seems that the recently released pyenv v1.2.14` fixes compatibility with tcl-tk, on GitHub issues. The solution was also written, so I will share it.

Solution
brew upgrade pyenv
brew install tcl-tk
Set environment variables
If you use bash
export PATH="/usr/local/opt/tcl-tk/bin:$PATH" export LDFLAGS="-L/usr/local/opt/tcl-tk/lib" export CPPFLAGS="-I/usr/local/opt/tcl-tk/include" export PKG_CONFIG_PATH="/usr/local/opt/tcl-tk/lib/pkgconfig" export PYTHON_CONFIGURE_OPTS="--with-tcltk-includes='-I/usr/local/opt/tcl-tk/include' --with-tcltk-libs='-L/usr/local/opt/tcl-tk/lib -ltcl8.6 -ltk8.6'"
- If you use fish
```shell:config.fish
set -x PATH "/usr/local/opt/tcl-tk/bin" $PATH
set -x LDFLAGS "-L/usr/local/opt/tcl-tk/lib"
set -x CPPFLAGS "-I/usr/local/opt/tcl-tk/include"
set -x PKG_CONFIG_PATH "/usr/local/opt/tcl-tk/lib/pkgconfig"
set -x PYTHON_CONFIGURE_OPTS "--with-tcltk-includes='-I/usr/local/opt/tcl-tk/include' --with-tcltk-libs='-L/usr/local/opt/tcl-tk/lib -ltcl8.6 -ltk8.6'"
pyenv install 3.7.4
python -m tkinter
