如何在docker容器中只设置Python2.7？

Question

我有node-app，在一个用例中，我使用^{}从node调用python脚本。我试图在docker上安装这个应用程序，我的Dockerfile看起来像这样

FROM debian:latest
# replace shell with bash so we can source files
RUN rm /bin/sh && ln -s /bin/bash /bin/sh
# update the repository sources list
# and install dependencies
RUN apt-get update \
&& apt-get install -y curl \
&& apt-get -y autoclean
# nvm environment variables
ENV NVM_DIR /usr/local/nvm
ENV NODE_VERSION 10.15.3
# install nvm
# https://github.com/creationix/nvm#install-script
RUN curl --silent -o- https://raw.githubusercontent.com/creationix/nvm/v0.31.2/install.sh | bash
# install node and npm
RUN source $NVM_DIR/nvm.sh \
&& nvm install $NODE_VERSION \
&& nvm alias default $NODE_VERSION \
&& nvm use default
# add node and npm to path so the commands are available
ENV NODE_PATH $NVM_DIR/v$NODE_VERSION/lib/node_modules
ENV PATH $NVM_DIR/versions/node/v$NODE_VERSION/bin:$PATH
# confirm installation
RUN node -v
RUN npm -v
RUN apt-get -y install python2.7
COPY package.json .
RUN npm install
COPY . .
CMD ["npm","run","start"]

在构建并运行这个容器之后，当我试图调用从节点调用python脚本的用例时，我得到了这个错误。在

你可以用“FROM”python:2.7“，基本映像。在

FROM python:2.7
 
 WORKDIR /usr/src/app
 
 COPY requirements.txt ./
 RUN pip install no-cache-dir -r requirements.txt
 
 COPY . .
 
 CMD [ "python", "./your-daemon-or-script.py" ]
；
