以下のようなメッセージに遭遇した場合の対処

pip3 install --upgrade pip

実施したこと(opensslの入れ替え?)

#yum groupinstall "Development Tools" -y
#yum install openssl-devel libffi-devel bzip2-devel -y

以下3行は「あまり見ない導入操作」。これが実は効く。
#yum install -y epel
#yum install -y openssl11-devel
#sed -i 's/PKG_CONFIG openssl /PKG_CONFIG openssl11 /g' configure

Python3.10.5をダウンロードします。
#wget https://www.python.org/ftp/python/3.10.5/Python-3.10.5.tgz

ダウンロードしたファイルを解凍します
#tar xvf Python-3.10.5.tgz
#cd Python-3.10.5

python3.10.5をインストールします
#./configure --enable-optimizations
#sudo make altinstall

PATHを通す
#ln -sf /usr/local/bin/python3.10 /usr/bin/python3
#ln -sf /usr/local/bin/pip3.10 /usr/bin/pip3

pythonバージョンを確認

#python3 --version
Python 3.10.5

環境設定

#echo 'LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/python3.9/lib"' >> ~/.bashrc
#echo 'PATH="$PATH:/usr/local/python3.9/bin"' >> ~/.bashrc
#source ~/.bashrc

pipのバージョンを確認します

#pip3 --version
pip 21.2.4 from /usr/local/lib/python3.10/site-packages/pip (python 3.10)

おそらく最近、よく失敗する操作のpipのUpgrade。
冒頭の「あまり見ない導入操作」を行うとできりようになりました。

#pip3 install --upgrade pip

無事Python3の導入と、pip3の導入およびUpgradeは完了!
