Common errors

error manim error: No module named 'manim' ↓

cause Manim not installed or wrong Python environment.

fix

Run pip install manim in your Python environment.

error AttributeError: 'Scene' object has no attribute 'play' ↓

cause Scene.construct method must call self.play(). This error occurs if you misspell `construct` or omit it.

fix

Ensure your scene class has a construct method (not __init__).

error ManimError: No available writer found ↓

cause FFmpeg not installed or not in PATH.

fix

Install FFmpeg from https://ffmpeg.org/ and add it to your system PATH.

Warnings

breaking Manim version 0.19.0 changed the default renderer to OpenGL. If you upgrade from an older version, scenes may look different. ↓

fix Use the CairoRenderer if you need the old behavior: manim -r cairo your_scene.py

deprecated The 'TexTemplate' class has been deprecated in favor of 'TexTemplateFromFile' in v0.18.0. ↓

fix Replace `TexTemplate` with `TexTemplateFromFile` or use the new `tex_template` parameter.

gotcha When using LaTeX (Text, Tex, MathTex), you need a working LaTeX distribution installed (e.g., MiKTeX or TeX Live). ↓

fix Install a LaTeX distribution or use the `–-tex_template` flag to point to a custom template.
