今天在安装应用的时候发生报错，部分报错信息如下：
Collecting av==8.0.3 (from -r requirements_inference.txt (line 1))

这个是在安装av==8.0.3时发生的报错，提示ModuleNotFoundError: No module named ‘distutils.msvccompiler’，意思是没有distutils.msvccompiler这个模块，主要是setuptools版本问题，你可以降低setuptools版本，比如65以下。
也可以用另一种解决方法，就是安装更高版本的av,而不是使用8.0.3版本，直接删除版本号即可。
