如何在 docker 容器中仅设置 python 2.7？

我有节点应用程序，在一个用例中，我使用以下命令从节点调用 python 脚本python-shell https://www.npmjs.com/package/python-shell。我正在尝试在 docker 上设置这个应用程序，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"]

构建并运行此容器后，当我尝试调用从节点调用 python 脚本的用例时，我收到此错误。

events.js:174
      throw er; // Unhandled 'error' event
      ^

帮助在 docker 容器中设置 python2.7 吗？

您可以使用 python 基础镜像

FROM python:2.7

该基础映像已预先配置 python，您无需单独安装 python。希望能帮助到你。
