Hello,

The end of the output from the script with verbose parameter :

Run npm run preview to preview your production build locally.

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install

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

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.
