Pygame - 混音器系统未初始化

Question

我一直在为我的社会研究课制作一个Pygame，我想为这个现有的游戏添加新元素。问题是，当我加载旧游戏时，没有进行任何重大更改，我收到错误。我似乎也查过一些警告，但大多数线程都是几年前的。我的错误如下：

Jordans-MacBook-Air:SS-Game Jordanxxi$ python ocean_cleaner.py
2017-05-26 12:23:15.729 Python[61184:1392206] Warning once: This application, or a library it uses, is using NSQuickDrawView, which has been deprecated. Apps should cease use of QuickDraw and move to Quartz.
May 26 12:23:15  Python[61184] <Error>: The function ‘SLSFlushWindow’ is obsolete and will be removed in an upcoming update. Unfortunately, this application, or a library it uses, is using this obsolete function, and is thereby contributing to an overall degradation of system performance.

有什么帮助吗？提前谢谢。

更新 - 我通过终端而不是空闲运行游戏。我仍然收到一个错误，但它有点不同。有人知道如何解决这个问题吗？

Traceback (most recent call last):

error: mixer system not initialized

Answer 1

我相信

你必须这样做：

pygame.mixer.init()

查看 mixer 的文档(当您遇到问题时，这始终是一个好主意 http://www.pygame.org/docs/ref/mixer.html！
