Raspbianにpython3.10をインストールできません：$ PYTHONHOMEと$ PYTHONPATHを設定できません。

Python3.10次のコマンドを実行してRaspbian 11にインストールしようとしました。

wget https://www.python.org/ftp/python/3.10.11/Python-3.10.11.tgz
tar -zxvf Python-3.10.11.tgz
cd Python-3.10.11
./configure --enable-optimizations
sudo apt update
sudo apt install -y build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev libffi-dev
sudo apt install -y build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev libffi-dev

ただし、次のエラーが発生します。

私が理解したのは、2つの変数を設定する必要がありますが、どうすればよいか$PYTHONHOMEわかり$PYTHONPATHません。
