1、pyaudio安装大背景
最近在做智能音箱，需要编写声音拾取代码，我先是百度两篇比较常见的用python进行录音的操作的文章：
python写一个录音小程序：
利用百度语言识别API实现语音识别python：
发现需要用到pyaudio，然后在其官网找到如何安装：
但是，在py虚拟环境中通过pip安装会报错，而采用sudo apt-get install python-pyaudio python3-pyaudio安装没有报错，但是在虚拟环境中不行。
注：全局安装不适用于python虚拟环境中，python虚拟环境和全局环境互不影响。
2、解决python虚拟环境中安装pyaudio走过的坑
坑一：utbutu16.10 安装pyaudio模块过程出现错误 fatal error: portaudio.h: 没有那个文件或目录 error: command 'x86_64-linux-gn
尝试：，发现没用
坑二：安装pyaudio找不到portaudio.h的问题
尝试：，发现无用
