Please install “ninja” so I can finish installing Manim

Harshit

Hi,

I’m trying to install the Manim Community Python package in my account on the FreeBSD shared host.

The build process stops because the ninja binary is missing.

Could you please run the following as root:

pkg install ninja

Once that’s done I’ll simply re-run:

pip install manim

and the installation should complete successfully.

The exact error I’m seeing is:

ERROR: Could not find a version that satisfies the requirement ninja (from versions: none)

Thank you for your help!

Harshit Ninja is already installed:

1.11.1

I'm trying to install the PyAV Python package (needed for Manim), but the build fails with:

error: use of undeclared identifier 'AV_HWDEVICE_TYPE_D3D12VA'

This means the FFmpeg headers on the server are outdated or incomplete. Even though ffmpeg -version shows 6.1.1, the header /usr/local/include/libavutil/hwcontext.h doesn't include AV_HWDEVICE_TYPE_D3D12VA.

Could you please update or reinstall FFmpeg along with its development headers?

Thanks for your help!

Harshit You can compile and install any version of ffmpeg you need in your home directory.
