Linux
=====
The installation instructions depend on your particular operating
system and package manager. If you happen to know exactly what you are doing,
you can also simply ensure that your system has:
- a reasonably recent version of Python 3 (3.9 or above),
- with working Cairo bindings in the form of
`pycairo <https://cairographics.org/pycairo/>`__,
- and `Pango <https://pango.gnome.org>`__ headers.
Then, installing Manim is just a matter of running:
.. code-block:: bash
pip3 install manim
.. note::
In light of the current efforts of migrating to rendering via OpenGL,
this list might be incomplete. Please `let us know
<https://github.com/ManimCommunity/manim/issues/new/choose>` if you
ran into missing dependencies while installing.
In any case, we have also compiled instructions for several common
combinations of operating systems and package managers below.
Required Dependencies
---------------------
apt Ubuntu / Mint / Debian
****************************
To first update your sources, and then install Cairo and Pango
simply run:
.. code-block:: bash
sudo apt update
sudo apt install build-essential python3-dev libcairo2-dev libpango1.0-dev
If you don't have python3-pip installed, install it via:
.. code-block:: bash
sudo apt install python3-pip
Then, to install Manim, run:
.. code-block:: bash
pip3 install manim
Continue by reading the :ref:`optional dependencies <linux-optional-dependencies>`
section.
dnf  Fedora / CentOS / RHEL
****************************
To install Cairo and Pango:
.. code-block:: bash
sudo dnf install cairo-devel pango-devel
In order to successfully build the ``pycairo`` wheel, you will also
need the Python development headers:
.. code-block:: bash
sudo dnf install python3-devel
At this point you have all required dependencies and can install
Manim by running:
.. code-block:: bash
pip3 install manim
Continue by reading the :ref:`optional dependencies <linux-optional-dependencies>`
section.
pacman  Arch / Manjaro
***********************
.. tip::
Thanks to *groctel*, there is a `dedicated Manim package
on the AUR! <https://aur.archlinux.org/packages/manim/>`
If you don't want to use the packaged version from AUR, here is what
you need to do manually: Update your package sources, then install
Cairo and Pango:
.. code-block:: bash
sudo pacman -Syu
sudo pacman -S cairo pango
If you don't have ``python-pip`` installed, get it by running:
.. code-block:: bash
sudo pacman -S python-pip
then simply install Manim via:
.. code-block:: bash
pip3 install manim
Continue by reading the :ref:`optional dependencies <linux-optional-dependencies>`
section.
.. _linux-optional-dependencies:
Optional Dependencies
---------------------
In order to make use of Manim's interface to LaTeX for, e.g., rendering
equations, LaTeX has to be installed as well. Note that this is an optional
dependency: if you don't intend to use LaTeX, you don't have to install it.
You can use whichever LaTeX distribution you like or whichever is easiest
to install with your package manager. Usually,
`TeX Live <https://www.tug.org/texlive/>`__ is a good candidate if you don't
care too much about disk space.
For Debian-based systems (like Ubuntu), sufficient LaTeX dependencies can be
installed by running:
.. code-block:: bash
sudo apt install texlive texlive-latex-extra
For Fedora (see `docs <https://docs.fedoraproject.org/en-US/neurofedora/latex/>`__):
.. code-block:: bash
sudo dnf install texlive-scheme-full
Should you choose to work with some smaller TeX distribution like
`TinyTeX <https://yihui.org/tinytex/>`__ , the full list
of LaTeX packages which Manim interacts with in some way (a subset might
be sufficient for your particular application) is::
collection-basic amsmath babel-english cbfonts-fd cm-super ctex doublestroke
dvisvgm everysel fontspec frcursive fundus-calligra gnu-freefont jknapltx
latex-bin mathastext microtype ms physics preview ragged2e relsize rsfs
setspace standalone tipa wasy wasysym xcolor xetex xkeyval
Working with Manim
------------------
At this point, you should have a working installation of Manim, head
over to our :doc:`Quickstart Tutorial <../tutorials/quickstart>` to learn
how to make your own *Manimations*!
