Installation
============

``msgspec`` may be installed via ``pip`` or ``conda``. Note that Python >= 3.8
is required. The basic install has no required dependencies.

**pip**

.. code-block:: shell

    pip install msgspec

**conda**

.. code-block:: shell

    conda install msgspec -c conda-forge


Optional Dependencies
---------------------

Depending on your platform, the base install of ``msgspec`` may not support
TOML_ or YAML_ without additional dependencies.

TOML
~~~~

The TOML_ protocol requires:

- Python < 3.11: `tomli`_ and `tomli_w`_ for reading and writing TOML.

- Python >= 3.11: `tomli_w`_ for writing TOML. Reading TOML is done using
  the standard library's `tomllib` and requires no additional dependencies.

You may either install these dependencies manually, or depend on the ``toml``
extra:

**pip**

.. code-block:: shell

    pip install "msgspec[toml]"

**conda**

.. code-block:: shell

    conda install msgspec-toml -c conda-forge

YAML
~~~~

The YAML_ protocol requires PyYAML_ on all platforms. You may either install
this dependency manually, or depend on the ``yaml`` extra:

**pip**

.. code-block:: shell

    pip install "msgspec[yaml]"

**conda**

.. code-block:: shell

    conda install msgspec-yaml -c conda-forge
