executor failed running [/bin/sh -c pip install -r requirements.txt]: exit code: 1

这是我的 Dockerfile 设置:

FROM python:3.6.13

ENV APP_HOME /app
WORKDIR $APP_HOME

COPY . /app

RUN pip install -r requirements.txt

ENTRYPOINT ["python app.py"]

可能需要在 pip install 之前执行 RUN apt-get update && apt-get install -y cmake。
