Set up a development environment of manim

Manim on Mac OS

Manim is an animation engine for explanatory math videos. It's used to create precise animations programmatically.

Installation

1. Install Python3.7

   • https://www.python.org/downloads/release/python-371/

     Or you can install with brew

     brew install python3

2. Install latex

   • https://miktex.org/download>

3. Install cairo ffmpeg pgk-config and sox with brew

   brew install cairo
   brew install pkg-config
   brew install ffmpeg
   brew install sox

4. Clone the Manim

5. git clone https://github.com/3b1b/manim.git
   cd manim
   pip3 install -r requirements.txt  //You may be failed on Mac with pip, but pip3 is OK.

Using virtualenv

1. Install with pip

​ pip3 install virtualenv

2. Creat a env and get into env

   virtualenv venv

   source venv/bin/activate

   • You may meet error here. To solve it you can follow next

     source ~/venv/bin/activate

   • You can get out of the env with

     deactivate

##Do a little modify

Find constant.py in your manim and get to line 23 ,find that says "Dropbox(3Blue1Brown)/3Blue1Brown Team Folder". We need to change this line to match the output folder you just created. In my case, I replaced that line with manim/media. You should replace it with whatever your file path is (keeping in mind that “~” in the line above is a short for the file path to your home directory).

else:
    MEDIA_DIR = os.path.join(
        os.path.expanduser('~'),
        "manim.media"
    )

Test

Remember to start in the venv and in the path manim

python3 extract_scene.py example_scenes.py SquareToCircle -p

python3 extract_scene.py example_scenes.py UdatersExample -p

Now, you can find the vedio created in manim/media

You are succeed if there is no error.
