ERROR: Failed building wheel for dlib

FROM python:3

WORKDIR ./app

COPY ./requirements.txt .

RUN pip install --upgrade pip \ && apt-get install -y --fix-missing\ && pip install --no-cache-dir -r requirements.txt

COPY . ./app

ENTRYPOINT [ "python", "./app.py" ]

In your Dockerfile.

FROM python:3
WORKDIR ./app
COPY ./requirements.txt .
RUN pip install -U pip wheel cmake
RUN pip install -r requirements.txt
COPY . ./app
ENTRYPOINT [ "python", "./app.py" ]

first install cmake and wheel with pip, the packages you install from the requirement.txt file are first downloaded and then installed, for this reason it fails to install dlib.
