如何从ubuntu镜像设置python for docker安装路径

Question

我从ubuntu:18.04制作了镜像并安装了python。

然而，当我在docker-compose中这样做的时候

command: python manage.py runserver

它显示路径错误。

也许我没有设定路径？？

但是我如何为docker用户设置路径？？

ERROR: for django  Cannot start service django: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"python\": executable file not found in $PATH": unknown
ERROR: Encountered errors while bringing up the project.


FROM ubuntu:18.04

ENV PYTHONUNBUFFERED 1

RUN apt-get -y update
RUN apt-get -y install emacs wget

RUN apt-get -y install apache2-dev mysql-client
RUN apt-get -y install mysql-server libmysqlclient-dev

RUN apt-get install -y software-properties-common
RUN add-apt-repository -y ppa:deadsnakes/ppa
RUN apt-get install -y python3.7

RUN apt-get install -y python-pip
RUN pip install uwsgi django mysqlclient tensorflow_hub django-mysql django-extensions djangorestframework django-filter requests_oauthlib mecab-python3 neologdn gensim janome --no-input
RUN pip install keras tensorflow==1.14.0 --no-cache-dir --no-input

RUN mkdir /code
WORKDIR /code

ADD ./src /code/

你可以用两种方法来解决这个问题(对我来说很有效)：

在docker-compose add中：

command: bash -c 'python manage.py runserver'

或者您可以在Dockerfile中添加CMD命令：

CMD: python manage.py runserver
