先にpythonをインストールするためのライブラリをインストール
sudo yum install zlib-devel ncurses-devel openssl-devel readline-devel libffi-devel bzip2-devel xz-devel sqlite-devel tk-devel
再度チャレンジ
pyenv install 3.8.19
今度は成功
Installed Python-3.8.19 to /home/tyano/.pyenv/versions/3.8.19
3.8系に変更
pyenv local 3.8.19
$ pyenv versions
system
* 3.8.19 (set by /home/tyano/.python-version)
環境変数を設定して再チャレンジ
export PYTHONHOME=/home/tyano/.pyenv/versions/3.8.19/
