.. _installation:
==============
Installation
==============
``sqlite-utils`` is tested on Linux, macOS and Windows.
.. _installation_homebrew:
Using Homebrew
==============
The :ref:`sqlite-utils command-line tool <cli>` can be installed on macOS using Homebrew::
brew install sqlite-utils
If you have it installed and want to upgrade to the most recent release, you can run::
brew upgrade sqlite-utils
Then run ``sqlite-utils --version`` to confirm the installed version.
.. _installation_pip:
Using pip
=========
The `sqlite-utils package <https://pypi.org/project/sqlite-utils/>`__ on PyPI includes both the :ref:`sqlite_utils Python library <python_api>` and the ``sqlite-utils`` command-line tool. You can install them using ``pip`` like so::
pip install sqlite-utils
.. _installation_pipx:
Using pipx
==========
`pipx <https://pypi.org/project/pipx/>`__ is a tool for installing Python command-line applications in their own isolated environments. You can use ``pipx`` to install the ``sqlite-utils`` command-line tool like this::
pipx install sqlite-utils
.. _installation_sqlite3_alternatives:
Alternatives to sqlite3
=======================
By default, ``sqlite-utils`` uses the ``sqlite3`` package bundled with the Python standard library.
Depending on your operating system, this may come with some limitations.
On some platforms the ability to load additional extensions (via ``conn.load_extension(...)`` or ``--load-extension=/path/to/extension``) may be disabled.
You may also see the error ``sqlite3.OperationalError: table sqlite_master may not be modified`` when trying to alter an existing table.
You can work around these limitations by installing either the `pysqlite3 <https://pypi.org/project/pysqlite3/>`__ package or the `sqlean.py <https://pypi.org/project/sqlean.py/>`__ package, both of which provide drop-in replacements for the standard library ``sqlite3`` module but with a recent version of SQLite and full support for loading extensions.
To install ``sqlean.py`` (which has compiled binary wheels available for all major platforms) run the following:
.. code-block:: bash
sqlite-utils install sqlean.py
``pysqlite3`` and ``sqlean.py`` do not provide implementations of the ``.iterdump()`` method. To use that method (see :ref:`python_api_itedump`) or the ``sqlite-utils dump`` command you should also install the ``sqlite-dump`` package:
.. code-block:: bash
sqlite-utils install sqlite-dump
.. _installation_completion:
Setting up shell completion
===========================
You can configure shell tab completion for the ``sqlite-utils`` command using these commands.
For ``bash``:
.. code-block:: bash
eval "$(_SQLITE_UTILS_COMPLETE=bash_source sqlite-utils)"
For ``zsh``:
.. code-block:: zsh
eval "$(_SQLITE_UTILS_COMPLETE=zsh_source sqlite-utils)"
Add this code to ``~/.zshrc`` or ``~/.bashrc`` to automatically run it when you start a new shell.
See `the Click documentation <https://click.palletsprojects.com/en/8.1.x/shell-completion/>`__ for more details.
