python - PyAudio 包未安装

Question

尝试使用 pip 安装 PyAudio 包显示错误，而其他包安装正常。我正在使用 python 3.7。为什么会出现此错误？

当运行 python 3.6 时这有效，但对于 python 3.7 则不起作用。

PyAudio 仅支持 python 3.6:

pip will fetch and install PyAudio wheels (prepackaged binaries). Currently, there are wheels compatible with the official distributions of Python 2.7, 3.4, 3.5, and 3.6.

解决方法是使用受支持的 python 版本，或者手动构建和安装 - 如果是后者，您需要确保安装和配置了正确的库。

我应该指出 PyAudio 似乎已被弃用。它自 2017 年 3 月以来未收到更新。因此我建议您为此寻找另一个软件包。
