如何在Dockerfile中添加PYTHONPATH的路径？这样当容器运行时它有正确的PYTHONPATH？我对码头工作者来说是新手.

我已添加ENV PYTHONPATH "${PYTONPATH}:/control"到Dockerfile,因为我想将目录添加/control到PYTHONPATH.

当我访问容器bash docker exec -it trusting_spence bash并打开python并运行下面的命令时,目录control不在列表中.

import sys print(sys.path)

FROM python:2
RUN pip install requests\
&& pip install pymongo

RUN mkdir control

COPY control_file/ /control

ENV PYTHONPATH "${PYTONPATH}:/control"

CMD ["python","control/control_file/job.py"]
