但是为啥其他人就能成功安装呢？

3.解决方法（Python3.5-3.9都可以解决）

发生上面的错误，是因为当前版本的pyav没有适合当前开发环境的版本（如我这边是Python 3.6），因此需要自己编译，而自己编译需要安装FFmpeg，进而导致因为没有FFmpeg引发了编译错误。因此有3种解决方法：

1.换Python版本（之前写的代码，可能要做Python版本适配工作，不推荐）；

2.自己装FFmpeg，然后自己编译（较为繁琐）；

3.直接下载我这边提供编译好的安装文件（含Python3.5-3.9，适用于Windows、Linux、MacOS平台），直接选择对应的版本，然后使用pip本地安装即可（推荐）。

由于方法1和2的局限性，建议使用方法3，直接安装：

3.1.获取编译好的安装文件

  1.百度网盘下载我提供的工具：Win10安装pyav出现报错（推荐，比CDSN便宜）：
