Logs

error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try 'pacman -S
    python-xyz', where xyz is the package you are trying to
    install.
    
    If you wish to install a non-Arch-packaged Python package,
    create a virtual environment using 'python -m venv path/to/venv'.
    Then use path/to/venv/bin/python and path/to/venv/bin/pip.
    
    If you wish to install a non-Arch packaged Python application,
    it may be easiest to use 'pipx install xyz', which will manage a
    virtual environment for you. Make sure you have python-pipx
    installed via pacman.

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.

Environment

• Client platform: Linux Manjero
• Python: 3.11.7
• cht-conf version: 3.21.4

Additional context
Run with --break-system-packages

This is not a cht-conf error per se, since python 3.11 the packages need to be installed within a virtual environment. However, the cht-conf installation document needs an update on this.
A workaround for this would be to create a virtual environment in the folder where you want to run the cht <command>. Another workaround is to create a single virtual environment anywhere in your system and export its path into the Linux PATH variable such that xls2xform-medic: (the binary that cht needs) is always available.
