pipで--break-system-packagesの問題について

python3 -m pip install ultralytics 
error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try brew install
    xyz, where xyz is the package you are trying to
    install.
    
    If you wish to install a Python library that isn't in Homebrew,
    use a virtual environment:
    
    python3 -m venv path/to/venv
    source path/to/venv/bin/activate
    python3 -m pip install xyz
    
    If you wish to install a Python application that isn't in Homebrew,
    it may be easiest to use 'pipx install xyz', which will manage a
    virtual environment for you. You can install pipx with
    
    brew install pipx
    
    You may restore the old behavior of pip by passing
    the '--break-system-packages' flag to pip, or by adding
    'break-system-packages = true' to your pip.conf file. The latter
    will permanently disable this error.

が出る問題に対しては、

~/.pip/pip.conf

[global]
break-system-packages = true

でとりあえず、過去の動作に戻せます。

brew installで入れば良いんですが、無いもの多いんで。

brew installで入るものが入ってしまった場合は、brew link xxxxxで、brew管理に戻せます。
