ERROR: Failed building wheel for dlib

DOCKERFILE

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" ]

Answer 1

在你的 Dockerfile 中。

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" ]

首先使用pip安装cmake和wheel，您从requirement.txt文件安装的软件包会先下载然后安装，用于这就是它无法安装dlib的原因。
