I have in my dockerfile to pip install ffmpeg but when I go into my terminal and try to locate the version, I get no result. Anyone have an idea on how to install ffmpeg, that would be greatly appreciated. Thanks

Hello,
Can you link exactly which PyPi ffmpeg Python package you are trying to install through your dockerfile? I was able to find an exact match which was ffmpeg · PyPI and several others

Also, please do provide the exact error message you are getting. Thanks!

If you can, please do send the Dockerfile you are using to install the dependencies as well.

Hello, thank you for the reply. Here is the error code I am getting from my discord python bot. I’m trying to play a local audio file but as I execute the command I get the error FFMPEG is not found. I believe its installed but not running. Any help is appreciated!

Hi Andy,

It looks like this package is expecting the ffmpeg application to be installed. Try adding a line to your Dockerfile like:
RUN apt-get update && apt-get install -y ffmpeg
