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

Manim runs on Python 3.8.

System requirements are：

- `FFmpeg <https://ffmpeg.org/>`__
- `OpenGL <https://www.opengl.org//>`__ (included in python package ``PyOpenGL``)
- `LaTeX <https://www.latex-project.org>`__ (optional, if you want to use LaTeX)
- `cairo <https://www.cairographics.org/>`_ (included in python package ``pycairo``. optional, if you want to use ``Text`` in manim)

Directly
--------

If you want to hack on manimlib itself, clone this repository and in
that directory execute:

.. code-block:: sh

   # Install python requirements
   pip install -e .

   # Try it out
   manimgl example_scenes.py OpeningManimExample
   # or
   manim-render example_scenes.py OpeningManimExample

If you run the above command and no error message appears, 
then you have successfully installed all the environments required by manim.

Directly (Windows)
------------------

1. `Install
   FFmpeg <https://www.wikihow.com/Install-FFmpeg-on-Windows>`__, and make sure that its path is in the PATH environment variable.
2. Install a LaTeX distribution.
   `TeXLive-full <http://tug.org/texlive/>`__ is recommended.
