mac + Pythonな環境で、mp3ファイルの音を鳴らしたいことがありました。
調べてみたところ、いくつかパッケージがあるようでした。
今回の場合は単に鳴らせればよかったので、一番手軽に扱えそうな playsound を使うことにしました。
TaylorSMarks/playsound: Pure Python, cross platform, single function module with no dependencies for playing sounds.
ただ、Githubのリポジトリを見たところ、最新バージョン 1.3.0 のリリースが3年くらい前でした。
そこで試してみたところ、最近のPythonバージョンでは動作しないと分かったので、メモを残します。
目次
環境
用意したPythonスクリプト
playsoundのREADMEを参考に、Pythonスクリプトを書きました。
また、Pythonスクリプトと同じ階層に、 mysound.mp3 というmp3ファイルを置きました。
from playsound import playsound def main(): playsound('mysound.mp3') print('終了します') if __name__ == "__main__": main()
動作するPythonバージョンの確認
上記スクリプトが動くかどうか、新しいバージョンから試していきます。

Python 3.10系ではインストールできたが、PyObjC が必要
続いて、Python3.10系で試してみたところ、インストールはできました。
% python --version Python 3.10.13 % pip install playsound Collecting playsound Using cached playsound-1.3.0.tar.gz (7.7 kB) Preparing metadata (setup.py) ... done Installing collected packages: playsound DEPRECATION: playsound is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option.

ただ、Pythonスクリプトを動かしてみたところ、エラーになりました。

playsound is relying on a python 2 subprocess. Please use `pip3 install PyObjC` if you want playsound to run more efficiently.

pip3 install PyObjCif you want playsound to run more efficiently.
でした。
また、Githubのissueにも似たような記載がありました。
https://github.com/TaylorSMarks/playsound/issues/132#issuecomment-1820177142
そこで、エラーメッセージに従い、 PyObjC をインストールしてみました。
https://github.com/ronaldoussoren/pyobjc
すると、PyObjCに関するパッケージが大量にインストールされましたが、エラーにはなりませんでした。
