Fix: ModuleNotFoundError: No module named 'moviepy.editor'

The one-command fix for the most common MoneyPrinterTurbo installation error — and why it happens.

The Error

You run python main.py or streamlit run webui/Main.py and get:

ModuleNotFoundError: No module named 'moviepy.editor'

This happens because moviepy 2.0.0 completely removed the moviepy.editor module that MoneyPrinterTurbo v1.1.0 depends on. The requirements.txt file doesn't pin an exact version, so pip happily installs the latest (broken) one.

The Fix (One Command)

pip install moviepy==1.0.3

That's it. Run this, restart the backend (python main.py), and MoneyPrinterTurbo will work. No config changes, no code edits needed.

Why This Happens

moviepy underwent a major rewrite between v1.x and v2.x:

moviepy 1.0.3 — The stable version. All imports go through moviepy.editor, which acts as a convenience module re-exporting everything you need.
moviepy 2.0.0+ — The rewritten version. Removed moviepy.editor entirely. Imports now go through moviepy.video, moviepy.audio, etc. Breaking change for any code written against the 1.x API.

MPT v1.1.0 was written before moviepy 2.0 existed. Its requirements.txt lists moviepy without a version constraint, so pip resolves to the latest (2.x) by default.

Other Projects Affected

This isn't just a MoneyPrinterTurbo issue. Any Python project that imports from moviepy.editor and doesn't pin moviepy==1.0.3 in its dependencies will break on a fresh install. Common victims:

Video automation scripts
AI video generation pipelines
Tutorial code that uses from moviepy.editor import VideoFileClip

Prevention tip: Always pin exact versions in production. Add moviepy==1.0.3 to your requirements.txt — not just moviepy.
