WARNING: You are using pip version 21.2.4; however, version 21.3 is available.
You should consider upgrading via the 'c:\python39\python.exe -m pip install --upgrade pip' command.

以下も同様なエラーがでます。
pip3 install --upgrade pip
python -m pip install --upgrade pip

Answer 1

ネット検索検索してみましたが、アップグレードではなく、一度アンインストールしてからインストールしなおすとうまくいくような投稿が多くみられました。

アンインストールしても問題ないようでしたら、以下を試してみるのはいかがでしょうか。

>python -m pip uninstall pip
>python -m ensurepip
>python -m pip install -U pip
