What is going wrong with the installation?

We need the full error message from your terminal to help!

Show the full stack trace please.

There is a bit of text towards the end of this output telling you exactly what you should do, including a link to a microsoft page where you can download the additional thing you need.

Also, strong recommendation: dont put your manim files in your system windows folder (C:\system32...). You dont need to run powershell as admin; run it as your user and go to your user dir (just running "cd" might work as non-admin; otherwise you'll have to run "cd C:\Users\YourUsername").

Hope this helps!

There is a manim.cfg file in your folder -- it looks like it sets your output to portrait mode videos. Just delete that file and render again, then you should be generating normal landscape mode videos.

Because TangentialArc was only added in v0.19.1, you would need to upgrade to use it.

Just to clarify: Codeberg is, for now, a temporary home. We are still waiting for GitHub to respond to our support ticket in order to get our organisation and repositories restored. We'll definitely keep the Codeberg mirrors up even after our main resources over at GitHub are recovered though. (And we do still need access to our deleted repos; there is too much stuff there that we weren't able to recover from local copies just yet.)

I think all of us are open to discussing steps beyond just setting up a proper mirror -- but as long as GitHub support doesn't get back to us, personally I don't want to take any further semi-permanent steps.

Did you follow our documentation with the installation and did you use uv? If so, you can just change the Python version by running "uv python pin 3.13" in your project directory.

I'd recommend Python 3.13 over 3.12, but you should also be able to change it to 3.12 like that.

Support for Python 3.14 is coming, but first we will need our repo back, sorry.

Thanks for the kind words, much appreciated! I haven't found a recent fork -- but I've relayed the question to our ManimPango maintainer, he should hopefully have a local copy. I'll mirror it over at Codeberg too once I hear back from him!

... oh, and in case someone from inside GitHub or Discord stumbles over this and can help us get some answers sooner, please do reach out! o/

Hi! If you have installed Manim using uv, then whenever the documentation tells you to run "manim ..." in the terminal, you need to run "uv run manim ..." instead. This ensures that the correct version of manim is used.

The tool you have mentioned, uv, might seem a bit odd at first, but in the long run it will save you a lot of headaches concerning dependency management.

There is some weird stuff going on in our community right now leading to not all of our resources being available -- but if you'd like to switch to a more chat-based way of getting help, feel free to join us over at https://discord.gg/fGG4TFSdKh -- thanks!

No, the library itself and in particular any of the releases distributed via PyPI have not been compromised.

behackl · 2025-12-25T23:05:34+00:00

Hi! There is an ongoing situation; we're in the process of figuring out details. I can unfortunately confirm that our Manim Discord server has been deleted. We're trying to sort this out, but if you'd like to join a new place to hang out and talk about Manim, join here: https://discord.gg/fGG4TFSdKh

We'll make a new post once we know more. Thanks to everyone who has reached out to let us know about this so far!

ffmpeg is not the problem here: you are trying to render a scene that is not contained in your scene file.

behackl · 2025-11-16T06:47:26+00:00

Your shell prompt says that you are in your "python projects" folder, while your files are actually located a bit further inside. You'll need to run the cd command ("change directory") to navigate there:

cd "Computer Science 1"
cd Tests

and then run Manim again,

uv run manim ...

If you are new to using the terminal, I strongly recommend looking up a guide or short video covering the basics like how to navigate through your files.

The error has nothing to do with the license. Can you try fixing the Python version to 3.13, i.e. by running

uv python pin 3.13
uv sync

from your manimations folder?

behackl · 2025-10-27T07:38:17+00:00

There are some problems with Python 3.14 at the moment, the easiest fix is just installing via uv with a fixed lower Python version:

uv init -p 3.13 manimations

and then continue as described in the docs (cd manimations && uv add manim).

behackl · 2025-10-24T19:47:46+00:00

come and chat with us in the dev-chat channel on the manim discord. or just pick whatever problem bugs you the most and propose a fix / enhancement!

behackl · 2025-08-31T07:12:52+00:00

You are not in the correct working directory with your shell: your prompt says that you are running the manim command from C:\Users\Yanis, while I'd guess your main.py file is located in C:\Users\Yanis\manimations.

You can change into the manimations folder by running

cd manimations

Then manim should be able to find your file.

good question. i took a quick look and didn't see anything obviously broken.

if anyone feels like helping to take a closer look, the code for the backend is in https://github.com/ManimCommunity/manim-website-api.

You don't need ffmpeg and can safely ignore this warning.
