pip install が効かない

22.04.4 のとき何も考えずに実行できたが、24.04 では python 3.10 から 3.12 に上がったのもあるが、エラーでインストールできず。

error: externally-managed-environment

    If you wish to install a non-Debian-packaged Python package,
    create a virtual environment using python3 -m venv path/to/venv.
    Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
    sure you have python3-full installed.
    If you wish to install a non-Debian packaged Python application,
    it may be easiest to use pipx install xyz, which will manage a
    virtual environment for you. Make sure you have pipx installed.
    See /usr/share/doc/python3.12/README.venv for more information.

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.


乱用はするな」という前提で(自己責任: 私は Docker も Jupyter もしない)

pip install package_name --break-system-packages


python3 -m pip config set global.break-system-packages true

すると pip install yt-dlp も成功できた。
