Python 无法安装PyAudio问题

一、错误与原因

在Windows上没有用于Python 3.7的轮子（预构建包）（有一个用于Python 2.7和3.4到3.6），因此需要在PC上准备构建环境以使用此包。因为有些软件包很难在Windows上构建，所以找到3.7的轮子更容易一些。

这是安装时报的错：

二、解决方法

我也是搜索了一下，参照stackoverflow这个回答：

• 打开python终端，在一个.py文件右键，选择Edit with IDLE->Edit with IDLE3.7(32 bit)打开，然后使用F5快速启动，即可看到你的python所有基本信息，比如我的版本是3.7.4，32位的

Python 3.7.4 (tags/v3.7.4:e09359112e, Jul  8 2019, 19:29:22) [MSC v.1916 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license()" for more information.

• 下载你所需的轮子，根据你的信息下载相匹配的轮子，比如如果是64 bit (AMD64)，就要下载PyAudio‑0.2.11‑cp37‑cp37m‑win_amd64.whl，而我需要下载的是上一个PyAudio‑0.2.11‑cp37‑cp37m‑win32.whl，以下圈出的是与64 bit(AMD64)适用的
  
• 找到相对应的轮子下载后，在轮子所在文件夹内安装

pip3 install PyAudio-0.2.11-cp37-cp37m-win32.whl

# 出现以下信息代表安装成功
D:\User\Downloads>pip3 install PyAudio-0.2.11-cp37-cp37m-win32.whl
Processing d:\user\downloads\pyaudio-0.2.11-cp37-cp37m-win32.whl
