잘 보면 Python.h라는 파일이 없다고 나온다.

먼저 오류 메시지에 나온데로 경로를 따라가 본다.
/user/include/python3.9/

잘 보니 python3.9라는 폴더가 없다...

여기 저기 찾아봤는데 처음에는 아래 명령어를 치라고 한다.
sudo apt-get install python3-dev
저 명령어를 쳤을 때 출력중 이런 문장이 나온다.
python3-dev is already the newest version (3.8.2-0ubuntu2).
나는 3.9를 사용하고 있는데 저녀석을 3.8에 설치하고 있다! (기본이 3.8이여서 그런듯 하다)

그래서 3.8이 아닌 3.9를 설치하기 위해 아래와 같은 명령어를 사용했다.
sudo apt-get install python3.9-dev

설치를 해주고 다시 pip3 install webrtcvad를 해줬더니...
