ReplayGain broke after updating Homebrew packages on macOS


For years, I had ReplayGain working with GStreamer as a backend but after updating my Homebrew packages I’m getting this error:

$ beet
Traceback (most recent call last):
  File "/usr/local/bin/beet", line 10, in <module>
  File "/usr/local/lib/python3.7/site-packages/beets/ui/", line 1266, in main

    plugins = _load_plugins(config)

    gi.require_version('Gst', '1.0')
AttributeError: module 'gi' has no attribute 'require_version'

How can I fix this?

My system:
macOS 10.14.6 • beets 1.4.9 • Python 3.7.7

yup, I’m in the same situation :confused:

Glad I’m not alone. :slight_smile:

For the time being I’ve disabled ReplayGain. I tried switching the backend to audiotools but that doesn’t exist as a pip package nor would it compile under macOS.

By the way, what is your experience with ReplayGain? Does it serve any practical purpose? One thing I dislike about it is that it slows down imports considerably.

I love ReplayGain, it’s a great way to browse music without massive changes in volume level between releases. Unfortunately, the only thing I’ve found that supports it on MacOS is foobar2000, which is currently extremely basic compared to the Windows version.

Issue fixed after latest update of Homebrew packages (gstreamer 1.16.2).
