问题：Fedora 38下pyenv安装Python 3.12.0时tkinter编译失败

执行pyenv install 3.12.0时出现以下错误：

~ pyenv install 3.12.0  
  Downloading Python-3.12.0.tar.xz...
  -> https://www.python.org/ftp/python/3.12.0/Python-3.12.0.tar.xz

  Traceback (most recent call last):

      import _tkinter # If this fails your Python may not be configured for Tk
      ^^^^^^^^^^^^^^^
  ModuleNotFoundError: No module named '_tkinter'
  WARNING: The Python tkinter extension was not compiled and GUI subsystem has been detected. Missing the Tk toolkit?
  Installed Python-3.12.0 to /home/raj/.pyenv/versions/3.12.0

已安装系统自带Python 3.11.6对应的tkinter包，但问题依旧：

~ sudo dnf install python3-tkinter -y

  Package python3-tkinter-3.11.6-1.fc38.x86_64 is already installed.
  Dependencies resolved.

系统详情

~ lsb_release -a     
LSB Version:    :core-4.1-amd64:core-4.1-noarch
Distributor ID: Fedora
Description:    Fedora release 38 (Thirty Eight)
Release:        38
Codename:       ThirtyEight

pyenv版本

~ pyenv --version    
pyenv 2.3.30

解决方案

安装编译Python所需的Tk开发依赖包：
```
sudo dnf install tk-devel
```
注：python3-tkinter是系统自带Python 3.11的运行时包，pyenv编译新Python版本需要底层的Tk开发库（包含头文件和编译依赖），所以必须安装tk-devel。
卸载已安装的有问题的Python 3.12.0：
```
pyenv uninstall 3.12.0
```
重新安装Python 3.12.0：
```
pyenv install 3.12.0
```
