ERROR: Could not build wheels for dlib

PROBLEM

도커 이미지를 만드는 데 다음과 같은 오류가 뜬다.:

Tons of lines of errors. But the below is a parts of them:

Troubleshooting steps:

오류 메시지에 dlib이 있는 걸 보니 dlib이 실행되기 위해서 도커 이미지 빌드 시에 반드시 설치해야 할 패키지가 있는 듯 싶다.

Solutions:

하단의 코드를 Dockerfile에 추가한다.

RUN apt-get update && \
    apt-get install -y \
    build-essential \
    cmake \
    libopenblas-dev \
    liblapack-dev \
    libx11-dev \
    libgtk-3-dev \
    python3-dev \
    python3-pip \
    python3-numpy \
    && rm -rf /var/lib/apt/lists/*
