pyenvを使ってptyhonをインストール。

私の環境はUbuntuなのでこのコマンドを実行。

sudo apt update; sudo apt install build-essential libssl-dev zlib1g-dev \
libbz2-dev libreadline-dev libsqlite3-dev curl llvm \
libncursesw5-dev xz-utils tk-dev libxml2-dev libxmlsec1-dev libffi-dev liblzma-dev libsasl2-dev python3-dev libldap2-dev

もう一度、pyenvでpythonのインストールを行い無事に成功。

pyenv install 3.11.1
