为什么在尝试安装pyaudio时出现错误？

Question

The first error whas Microsoft Visual C++ 14.0 is not installed and I fixed it... Now when I try to install pyaudio I get another error. (I've Windows 10)

I've installed all visual studio's packages... I tried also to use wheel installation but it says that wheel is not supported on this platform

Answer 1

From the official docs :

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

That being said and seeing your error message: 'portaudio.h': No such file or directory error , I think you have not installed this dependency.

The key part here is that PyAudio only provides python bindings to the Portaudio library, but does not include the library itself, unless you install using a .whl , but these are not available for python 3.7 . Again, from the docs (emphasis mine):

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.

So your solution is to either download and install the missing library, or move to a python version for which there are pre built wheels that include Portaudio
