为什么在尝试安装pyaudio时出现错误？

Question

没有安装Microsoft Visual C ++ 14.0时出现的第一个错误，我已将其修复。。。现在尝试安装pyaudio时出现另一个错误。 （我有Windows 10）

我已经安装了所有Visual Studio的软件包...我也尝试过使用滚轮安装，但是它说此平台不支持滚轮

Answer 1

从官方文档 ：

要从源代码构建PyAudio，您还需要构建PortAudio v19

话虽如此，然后看到您的错误消息： 'portaudio.h': No such file or directory error ，我认为您尚未安装此依赖项。

此处的关键部分是PyAudio仅提供与Portaudio库的python绑定，但不包括该库本身，除非您使用.whl安装，但这些.whl不适用于python 3.7 。 再次，从文档（重点是我的）：

pip将获取并安装PyAudio轮子（预包装的二进制文件）。 当前，有一些轮子与Python 2.7、3.4、3.5和3.6的官方发行版兼容。 对于那些版本，既有32位轮子又有64位轮子。

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， Portaudio预先构建了包含Portaudio轮子
