为什么我不能导入 PyAudio？

Question

我试图导入 PyAudio，但它一直给我一个错误。如果这是我的计算机的问题，我使用的是 Windows 64x 和 Python 3.9.4。这是错误：

ERROR: Command errored out with exit status 1:

如果有人知道如何解决此问题，请告诉我！我还在学习如何阅读 Python 日志/错误！谢谢！

Answer 1

注意这一点：

error: Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/

看来您需要 C++ 14.0。 我不确定哪个链接会更好，但这里有一些我发现的。 https://visualstudio.microsoft.com/visual-cpp-build-tools/ https://visualstudio.microsoft.com/downloads/

Answer 2

当前 PyAudio PIP 包未预编译，请参阅预编译包列表 [此处]。对于 Python 3.9，它以源代码形式提供，直到 Python 3.6 才被编译。

源码编译包需要安装Visual Studio，即使编译也不一定能成功，所以最好安装二进制预编译包。

但是还有一个包的替代来源，here。下载文件PyAudio‑0.2.11‑cp39‑cp39‑win_amd64.whl并通过python -m pip install PyAudio‑0.2.11‑cp39‑cp39‑win_amd64.whl安装。这个包是预编译的，不需要 Visual Studio。
