为什么在我尝试安装 pyaudio 时出现错误？

Question

第一个错误是未安装 Microsoft Visual C++ 14.0，我修复了它...现在，当我尝试安装 pyaudio 时，出现另一个错误。（我有 Windows 10 个）

我已经安装了所有 visual studio 的软件包...我也尝试使用 wheel 安装，但它说此平台不支持 wheel

来自官方docs:

To build PyAudio from source, you will also need to build PortAudio v19

话虽这么说，但看到您的错误消息：'portaudio.h': No such file or directory error，我认为您还没有安装此依赖项。

这里的关键部分是 PyAudio 仅提供 python 绑定到 Portaudio 库，但不包括库本身，除非您使用 .whl，但这些不适用于 python 3.7。同样，来自文档（强调我的）：

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. For those versions, both 32-bit and 64-bit wheels are available.

因此您的解决方案是下载并安装缺少的库，或者移动到 python 版本，该版本有包含 Portaudio

的预制轮子
