推荐答案

如果使用miniconda映像，您必须先创建一个新环境并激活它，然后才能安装软件包并在docker文件中运行该程序。

If you use miniconda image you have to create a new environment and activate it prior to installing the packages and run the program in your docker file. Something like:

FROM continuumio/miniconda3 RUN apt-get update && apt-get install -y python3 RUN apt-get install -y python3-pip RUN apt-get install -y build-essential COPY requirements.txt / RUN ["conda", "create", "-n", "myenv", "python=3.4"] RUN /bin/bash -c "source activate myenv && pip install --trusted-host pypi.python -r /requirements.txt" ADD ./glm-plotter /code WORKDIR /code RUN ls . CMD /bin/bash -c "source activate myenv && python glm-plotter.py"
