如何设置从图像ubuntu安装docker的python路径

Question

我从ubuntu:18.04制作了这个映像并安装了python

但是当我在docker compose中这样做的时候

command: python manage.py runserver

它显示了路径错误

也许我没有设定路线

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/

你可以用两种方法解决这个问题（对我来说很有效）：

在docker compose中添加：

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

也可以在Dockerfile中添加CMD命令：

CMD: python manage.py runserver
