pip 외부 라이브러리 설치와 관련된 질문입니다.

Question

안녕하세요. 수업 너무 알차게 잘 듣고 있습니다. 그러나 수업을 듣는 도중 문제가 생겨 질문을 드립니다. pip 외부 라이브러리 설치 중에 일어난 에러입니다. pip install numpy pandas matplotlib을 입력하였는데 Using cached numpy-1.19.2.zip (7.3 MB) Installing build dependencies ... done Getting requirements to build wheel ... done Preparing wheel metadata ... - 에서 넘어가지 않고 에러가 뜹니다 다음은 에러 전문입니다. 어떻게 해결해야 할까요?

답변이 늦었습니다. 에러 로그를 보니, Microsoft Visual C++ 14.0 이 필요한가 보네요. error: Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/ 로그에서 제안하듯이, Visual Studio 를 설치해보시면 어떨까요? ( https://visualstudio.microsoft.com/downloads/)
